A VIABLE DOMESTIC URANIUM INDUSTRY?
Mary Byrd Davis Uranium Enrichment Project
11/23/2001
Executive
Summary
Supporters of the nation’s faltering uranium
enrichment industry argue that for reasons of national security we need to
maintain a domestic supply of uranium fuel. An examination of the US fuel chain,
however, shows that no matter how strong the enrichment sector, the nation would
not have a viable domestic uranium industry without major changes elsewhere
along the fuel chain.
Key links in the chain, uranium mining and fuel
manufacture, are dominated by foreign corporations The production of
electricity is still for the most part the domain of US-owned companies,
but the US Nuclear Regulatory Commission supports legislation that would
remove the current limitations on foreign ownership of nuclear power
plants. The industry is not able to dispose safely of its waste; and the
academic infrastructure that trains nuclear engineers and scientists is
fading away.
Legislation now pending in Congress and additional steps
under consideration by the Bush administration give an idea of the
initial payment that would be required to recreate a domestic industry.
The desiderata include subsidies to the mining and conversion
industries; reauthorization of the Price-Anderson Act, which limits the
liability of owners and operators of nuclear power plants and also
protects the US Enrichment Corporation (USEC); streamlining of the
licensing of new nuclear power plants; development of "advanced
fuel recycling technology"; and grants, fellowships, and
scholarships for students and faculty associated with nuclear
engineering programs.
Nevertheless, a domestic nuclear industry is not an
essential. If HEU is in demand for new nuclear weapons or submarine
fuel, it can be obtained from the weapons that the Bush administration
plans to dismantle. Nuclear power plants generate 20% of the electricity
that we consume. The Union of Concerned Scientists has found that the
nation can meet 20% of its electricity needs through renewable energy
resources by 2020, while Amory and Hunter Lovins report that efficient
use of energy alone can save four times nuclear power’s output. Energy
gains through renewables and energy efficiency cost less than gains
through construction of new power plants. A dollar invested in energy
efficiency produces roughly double the reduction in greenhouse gasses
that a dollar invested in the nuclear industry does.
In fact, the domestic industry is a liability, as the
attack on the World Trade Center made evident. Nuclear power plants and,
in particular, their pools of irradiated fuel have the potential for
releasing radioactivity that could kill thousands of people. Such a
catastrophic release could be caused by an accident or by a terrorist
action. The transmission lines that distribute the power from such
centralized plants are subject to disruptions by terrorists and by
extremes of weather. Because electricity grids are interconnected,
disruptions could affect large areas. Apart from the terrorist threat,
management of irradiated fuel poses an intractable problem.
Given the fact that a domestic uranium industry is not
necessary and given the threat of nuclear terrorism, the prudent course
would be to phase out the industry as rapidly as practicable. In the
meantime, the federal government should not, in our view, subsidize the
industry or change laws and regulations to make possible the licensing
of nuclear plants by foreign entities or to streamline the licensing of
new nuclear plants. If the domestic industry cannot survive without
federal subsidies, foreign capital, and a reduction in public oversight,
it should not survive.
We also recommend that the Megatons to Megawatts program
be drastically changed. Under this program the United States imports for
use in US reactors uranium that has been downblended from Russian highly
enriched uranium (HEU). The program in its entirety would be an asset
only if the nation benefits from continuing to obtain electricity from
nuclear power plants. By using the downblended uranium in nuclear
reactors, the United States creates plutonium, which, like HEU, is the
stuff of nuclear weapons, and contributes to the problem of what to do
with irradiated fuel. Securing the stocks of Russian HEU is too serious
a matter to be left to the vicissitudes of the commercial nuclear
industry, and the blending down should, for security reasons, take place
more rapidly than the uranium market could absorb the resulting
material.
We recommend that the United States purchase outright
all the HEU that Russia is willing to sell, enable Russia to downblend
the HEU rapidly, and then have it stored, if possible, in Russia. We
also recommend that the federal government give high priority to
securing nuclear materials and protecting nuclear plants and their
irradiated fuel within the United States.
In addition we recommend that the federal government
encourage the implementation of energy efficiency measures and the
development and application of renewable energy technologies. The
government should give workers who are displaced by the closure of
nuclear plants opportunities to be involved in the new decentralized
energy system that is rapidly emerging. The manufacture of solar
equipment or fuel cells has a brighter future than the enrichment of
uranium.

A VIABLE DOMESTIC URANIUM INDUSTRY?
Mary Byrd Davis Uranium
Enrichment Project
The US nuclear industry has for years “used
self-sufficiency in uranium fuel as a major selling point.”[i]
Now the Bush administration is reviewing the status of
“domestic nuclear fuel, ‘in part to determine whether a
domestic uranium enrichment industry is economically feasible or
necessary.’”[ii]
Entities urging the government to support the faltering
enrichment industry argue that for reasons of national security we need
to maintain a domestic supply of uranium fuel.
An examination of the US fuel chain, however, shows that, no
matter how strong the enrichment sector, the nation would not have a
viable domestic uranium industry without major changes elsewhere along
the fuel chain.
Key links in the chain: uranium
mining and fuel manufacture are dominated by
foreign corporations. The
production of electricity is still for the most part the domain of
US-owned companies, but the US Nuclear Regulatory Commission supports
legislation that would remove the current restriction on foreign
ownership of reactors. The industry is not able to dispose safely of its waste; and
the academic infrastructure that trains nuclear engineers and scientists
is fading away.
In this report, we examine the fuel chain segment by segment with
an eye to foreign influences and the ability of various links in the
chain to support the nuclear power sector.
We then look briefly at what it would take to revive the entire
industry, and draw conclusions. Basic
information about individual facilities is provided in the appendix.
I. DOES
THE UNITED STATES NOW HAVE A VIABLE DOMESTIC INDUSTRY?
I.A.
Mining
The mining of uranium ore in the United States is dwindling.
Furthermore, foreign companies own the only three mines that are
active as of November 2001.
The United States in
2000 produced by mining a total of only 3.1 million pounds of U3O8
(uranium oxide), 31% less than in 1999. The 3.1 million pounds came from
one underground mine and four in situ leaching (ISL) operations. Some
additional uranium was recovered from waste mine-water and from
restoration activities at closed ISL sites.[iii]
(In in situ leaching, the uranium ore remains in the ground.
A leaching liquid is injected into the ground through wells; the
liquid, now bearing uranium, is pumped out through other wells.)
The underground mine is
the Schwartzwalder Project in Colorado, owned by the Cotter Corporation,
which is 100% owned by the US firm General Atomics.[iv].
The mine is no longer in operation.
The four in situ leaching operations are Crow Butte in Nebraska;
and Highland, Christensen Ranch, and
Smith Ranch in Wyoming. Crow
Butte and Highland are owned by companies that are 100% subsidiaries of
Cameco, a Canadian corporation; Smith Ranch is owned by a 100%
subsidiary of Rio Algom Mining Corporation, which is in turn 100% owned
by the British company Billiton Plc.
Christensen Ranch, which closed before the end of 2000, is 71%
owned by the French company Cogéma through COMIN.
Hydro Resources, a
subsidiary of the US company Uranium Resources, Inc. is in the process
of obtaining authorization to construct and operate four ISL projects in
the Eastern Navajo Agency in northwestern New Mexico. The company has
said that it will not begin mining until the price of uranium reaches
$15.00 a pound. Currently
uranium is selling at under $9.00 a pound.
Residents of the area, with the support of national
organizations, are fighting the planned mining, in particular because of
fears of water pollution.[v]
Hydro Resources may have been counting on a $30 million subsidy
from the federal
government, as it would have been eligible for funding for in situ
mining contained in HR 4 and S 472 before the Senate.
However, opponents of the mines have convinced key legislators to
remove the subsidy from the bills.[vi]
Known uranium reserves in the United States that are recoverable
at a cost of $30 per pound of U3O8 total 271 million pounds; those
recoverable at $50 per pound, total 904 million pounds (that is, the
equivalent of five years or eighteen years supply respectively for US
reactors). Total
expenditures for uranium exploration and development in the United
States in 2000 were $6.7 million, $5.6 million for surface drilling and
$1.1 million for land acquisition.
The total represents a reduction of 25% from the previous year.
I.B.
Concentration
Production of uranium
concentrates in the form of U3O8 totaled approximately 4.0 million
pounds in 2000, a reduction of 14% from the previous year. Only one conventional mill and four unconventional plants
operated during 2000.
The conventional mill is
the Canon City Mill in Colorado which, like the Schwartzwalder Project,
is owned by the Cotter Corporation, a subsidiary of General Atomics.
As of the end of June 2001, this mill was not operating.
The unconventional plants are the four in situ leach
operations listed above. (The operations may be termed “plants,”
because the uranium-bearing water is processed after it has been pumped
up to the ground.) As
indicated above, Christensen Ranch is no longer active.
Production of
concentrate in 2001 is down from production in 2000.
In the first two quarters of 2000, production totaled a little
more than 2.0 million pounds; in the first and second quarters of 2001,
production totaled just under 1.5 million pounds, a decrease of roughly
28%. The Energy Information
Administration (EIA) predicts that production for 2001 as a whole will
be less than 3.0 million pounds.
Owners and operators of
US civilian nuclear power reactors have calculated that they will need
for refueling purposes natural uranium equivalent to a maximum of 518.4
million pounds of U3O8 during the ten-year period 2001-2010 or about 50
million pounds of U3O8 per year. In
2000, uranium equivalent to 51.4 million pounds of U3O8 was used by US
utilities.[vii]
Thus the domestic industry is far from meeting the need.
I.C.
Conversion
The United States has
only one operating plant to convert U3O8 (uranium oxide), known as
yellowcake,[viii]
to UF6 (uranium hexafluoride), the feed for plants that enrich uranium
by the gaseous diffusion or centrifugation method.
The plant, Honeywell Specialty Chemicals in Metropolis, Illinois,
has a nominal capacity of 12,700 metric tons[ix]
of uranium per year. It is
owned by Honeywell International Corporation, based in Minneapolis.
ConverDyn, a joint venture of Honeywell and General Atomics,
markets the UF6 produced at the plant.
A conversion plant owned by Sequoyah Nuclear Fuels in Gore,
Oklahoma, stopped converting U3O8 to UF6 in 1992 and is now undergoing
decommissioning.
The Honeywell plant has
suffered financially in the past few years because of a decline in the
price paid for conversion. The
cost of conversion on the spot market fell from $5.85 per kilogram of
uranium as UF6 early in June 1997 to $2.30 per kilogram in August 2000.[x]
ConverDyn reported in late 2000 that the average cost of
production at the Metropolis plant for 2001 through 2003 will be $4.56
per kilogram of uranium, and that, in spite of diversification
initiatives, the plant was in danger of closing. ConverDyn blamed the drop in prices on sales by USEC of
natural and enriched uranium hexafluoride obtained from DOE and from
Russia.[xi]
The conversion services in the Russian high-enriched uranium that
USEC imports in downblended form, as executive for the US-Russian HEU
accord, is, in fact, roughly the equivalent of the production of the
Metropolis plant in 2000, 9180 metric tons of uranium as UF6 from Russia
and 9300 metric tons from Metropolis. Prices are, however, rebounding.
As of June 2001, the price in the spot market was $5.00 per
kilogram of uranium as UF6.[xii]
The Metropolis plant does not have sufficient capacity to meet
the conversion needs of US reactors, which total approximately 17,500
metric tons of natural uranium a year.[xiii]
However, even if it did, US utilities would be likely to buy from a mix
of domestic and foreign sources.
I.D. Enrichment
Only one US company enriches uranium, the United States
Enrichment Corporation (USEC). It
is struggling to remain profitable, but at the present time does not
have the capacity to meet the enrichment needs of US utilities.
USEC came into existence
in July 1993 as a government-owned corporation to take over enrichment
operations, which had formerly been run by DOE and its predecessors.
In July 1998, USEC, through an initial public stock offering,
became a privately owned company. USEC
leases from DOE two enrichment plants, the Paducah Gaseous Diffusion
Plant in Kentucky and the Portsmouth Gaseous Diffusion Plant in Ohio.
Until mid 2001, Paducah enriched uranium hexafluoride only to 2.75%
uranium 235. The UF6 was
then shipped to Portsmouth to be further enriched to the level desired
by customers, generally between 3.5% and 5% uranium 235.
USEC, though a private
company, is the US executive agent for the US-Russian HEU accord.
Through the accord, the United States agreed to purchase over a
twenty-year period, 500 metric tons of highly-enriched uranium (HEU)
taken from Russian weapons and downblended in Russia to low-enriched
uranium.[xiv]
As of September 2001, with
implementation of the agreement in its seventh year, USEC had
imported 125 metric tons of HEU in downblended form (22.4 million
SWU).[xv]
There is, however, an inherent conflict between USEC’s role as
a private company, which must strive to make a profit for stockholders,
and its role as an instrument of US non-proliferation policy.
The enrichment plants that USEC leases are more than forty years
old and use a technology that is no longer competitive, largely because
it requires large amounts of electricity.
A gas centrifuge plant typically demands 2,500 kilowatt hours per
Separative Work Unit (SWU--a means of measuring the work of enrichment).[xvi]
A centrifuge plant requires only 50 to 400 kilowatt hours per SWU.[xvii]
Two of USEC’s competitors, Minatom in Russia and Urenco in
Germany, the Netherlands, and United Kingdom, use centrifuges.
France is planning to replace the Eurodif plant, another USEC
competitor, with centrifuges when that plant reaches the end of its
useful life.
USEC’s financial situation has deteriorated since
privatization, to such an extent that various stockholders are suing for
misrepresentation at the time of the Initial Public Offering. Net income
was $152.4 million for FY 1999; $35 million for FY 2001.
USEC has in the past been wont to blame its lack of financial
success on its role as executive agent for the US-Russian HEU accord.
In May 1999, USEC stated, “Cost of sales has been, and will
continue to be, affected by amounts paid to purchase SWU under the
Russian Contract at prices that are substantially higher than marginal
production cost at the plants. As
a result of Russian SWU purchases, USEC has operated the plants at lower
production levels resulting in higher unit production costs.”[xviii]
Nevertheless, in 2001 USEC is counting on Russian uranium to
enable it to stay afloat financially.
As a cost-cutting measure USEC decided to shut down the
Portsmouth plant. To do so,
it had to upgrade the Paducah plant to enable this plant to enrich
uranium hexafluoride to up to 5.5% uranium 235. The US Nuclear Regulatory Commission certified the new enrichment level in March 2001.
The Portsmouth plant closed in May 2001 and, with the help of
government funding, is now on cold standby.
Paducah sends enriched uranium to Portsmouth for transfer and
shipping, but no other procedures are carried out at that location.
Since stopping
enrichment at Portsmouth, USEC has been severely limited in its
production capability. In 1998, the Paducah plant’s nominal capacity
was 11.3 million SWU per year. However,
USEC’s 10K report to the SEC for FY 2001 states “USEC estimates that
the maximum capacity of the existing equipment at the Paducah plant is
about 8 million SWU per year.” The
report continues “USEC expects to utilize the production equipment to
produce about 5 million SWU in fiscal 2002.”
Some observers think that USEC will experience difficulty in
producing more than 4.3-4.5 million SWU a year at Paducah, in part
because the plant reduces production in the summer to cut electricity
costs.
Even at 8 million SWU, Paducah would not be able to turn out
enough SWU to meet the demands of US utilities if they were to try to
buy enrichment services only from USEC.
In 2001 US utilities purchased 11.8 million SWU (5.2 million from
USEC and 6.6 million from foreign sources).[xix]
Furthermore, USEC cannot meet, with Paducah’s production, the
demands of its present foreign and domestic customers—approximately 11
million SWU per year.
Whether Paducah can
actually produce enriched uranium that will meet the requirements of
utilities is an open question. According
to an informed source, as of early November 2001, Paducah had not been
able to enrich uranium hexafluoride to 5% uranium 235 and had not been
able to provide laboratory samples to verify commercial quality.
USEC is obviously
dependent on obtaining at least part of the enrichment service that it
sells, from sources other than future production at Paducah.
At the close of FY 2001, the company had a SWU inventory valued
at $918.3 million, up from $596 million at the close of FY 2001[xx];
and BWX Technologies is blending down for USEC 50 metric tons of HEU,
containing 3.4 million SWU, a gift from DOE at the time of
privatization. However, the
main source on which USEC has been planning is the Russian Federation.
During its 2001 fiscal
year, USEC paid around $90 per SWU for Russian enrichment service.[xxi]
The contract under which USEC buys SWU from Russia expires at the
end of 2001. USEC and
Tenchsnabexport (Tenex), the Russian executive agent, negotiated a
tentative agreement in 2000 under which the SWU imported under the HEU
agreement would be market-priced, but USEC would buy additional
commercial SWU from Russia.
The Bush administration
has not approved the tentative agreement, and the Russian government may
no longer be willing to accept it.
The administration, in fact, told USEC in October to negotiate a
price for and to order weapons-uranium SWU from Russia but not to import
commercial SWU for calendar year 2002.
The final price for 2002 could scarcely be lower than the price
for 2001, since under the terms of the existing contract between USEC
and Tenex, the 2001 price is in effect for 2002 if no new agreement is
reached.
The price of the Russian
SWU is crucial to USEC’s balance sheet.
In USEC’s 1999
fiscal year, 31% of its produced
plus purchased supply of SWU came from the Russian federation.
USEC intends to obtain 60%
from Russia in 2002. According
to an informed source, the cost to USEC for enriched product from
Paducah, at less than 4% uranium 235, averages around $140 per SWU ($109
for production costs at Paducah, about $5 for transfer and shipment at
Portsmouth, and about $25 for costs at headquarters (overhead and debt).
The market price for SWU in the United States under long-term
contracts was $102 per SWU on June 30, 2001.[xxii]
Apparently USEC had hoped to pay Russia around $75 per SWU in
2002 and also to import commercial SWU.[xxiii]
Combining the high-cost Paducah product with low-cost Russian SWU
would enable it to sell SWU at a competitive price.
Additional factors
complicate the operation of the Paducah plant. Paducah, like Portsmouth,
uses Freon, an ozone destroying chemical, as its primary coolant.
The Freon has long leaked “from pipe joints, sight glasses,
valves, coolers and condensers.”
USEC states that it has enough Freon to supply the Paducah plant
“through at least fiscal 2003,”[xxiv]
but production of Freon ended in the United States in 1995.
After USEC’s supply runs out, price, if not availability, will
likely pose difficulties.[xxv]
Another complicating factor is the inability of Paducah to enrich
uranium to the level that will be required by at least one version of
the proposed new Pebble Bed Modulated Reactor-- 8.1% uranium 235.[xxvi]
According to its 10-K report for FY 2001, USEC plans
to select an advanced enrichment technology in FY 2002.
It will choose between Silex, a laser-based technology, which the
Australian firm Silex Systems Limited is developing (USEC is paying for
exclusive rights to the application of Silex to uranium enrichment) and
gas centrifuge technology developed by DOE, on which USEC has been
working with University of Tennessee-Battelle at Oak Ridge.
During the past year they cooperated, at USEC’s expense, under
a DOE-approved Cooperative Research and Development Agreement or Crada,
which USEC hopes that DOE will extend.
USEC “believes new
enrichment facilities using either gas centrifuge or Silex could be
ready by the end of the decade.”[xxvii]
Following a successful demonstration of centrifuges, USEC would license,
construct, and operate a lead cascade “at a gaseous diffusion
plant.” It would then
seek financial partners to construct a centrifuge plant, which it would
expand incrementally.[xxviii]
Whether USEC can survive until it is ready to deploy a new
technology and whether the technology that USEC chooses will operate
successfully are open questions.
Meanwhile, a US alternative to USEC is in the offing.
Officials of Exelon and Duke have sent a letter to President Bush
stating that a group of US utilities and additional partners are
“actively seeking to deploy proven and competitive enrichment
technology in the US.” They
asked the administration not to take any steps that would give a special
advantage in building a new plant in the United States to USEC and also
asked the administration to consider appointing a group known as Nuclear
& Energy Security Partnerships as a second executive agent under the
US-Russian HEU agreement.[xxix]
The “additional partners” include Urenco, which owns and
deploys in Europe centrifuge technology that is now in its sixth
generation. In October the chief executive officer of Urenco briefed
Congressional leaders in Washington on Urenco centrifuge technology.
Urenco is owned by the governments of the United Kingdom and the
Netherlands and by two German utilities. Again we are back to the
foreign factor.
I.E. Fuel
fabrication
Fabrication of fuel for civilian reactors, like production of
uranium, is today largely in foreign hands.
Four plants located in the United States produce civilian fuel.
The only one that can be considered a US-directed operation is
Global Nuclear Fuel—Americas, which manufactures fuel for boiling
water reactors in Wilmington, North Carolina.
The owner is Global Nuclear Fuel--General Electric 51%, Hitachi
Ltd. 24.5%, and Toshiba Corporation 24.5%.
Westinghouse Electric, which produces fuel for pressurized water
reactors in Columbia, South Carolina, is now a 100% subsidiary of the
British-owned British Nuclear Fuels Ltd (BNFL). (Westinghouse Electric
closed a fuel production plant in Hematite, Missouri, in the summer of
2001 following BNFL’s purchase of the nuclear fuel operations of
Swiss-based ABB, which had owned the plant.)
Framatome ANP, which operates a plant in Lynchburg, Virginia that
produces fuel assemblies, and a plant in Richland, Washington, that
produces pellets and assemblies for boiling water and pressurized water
reactors, is owned 66% by the French company Framatome and 34% by the
German company Siemens. (Prior
to the creation of Framatome ANP in 2001, Framatome-Cogéma Fuels, a subsidiary of two French
companies, had owned the Lynchburg plant, and Siemens Power Corporation,
the Richland plant.)
For two additional plants the fabrication of fuel for the US Navy
is a major project. As
would be expected, these plants, which are authorized to handle highly
enriched uranium, are owned by US companies.
They contribute to the commercial fuel chain, notably by blending
down uranium.
In order to render surplus plutonium removed from weapons
unsuitable for future weapons, the US Department of Energy (DOE) has
contracted with a consortium to build a plant to produce mixed oxide
fuel at DOE’s Savanna River site, also to manage the irradiation of
the fuel in civilian reactors, and the eventual deactivation of the fuel
production plant. The
members of the consortium are Duke Engineering Services, Stone and
Webster, and Cogéma, Inc., the US subsidiary of the French company Cogéma.
Subcontractors include Nuclear Fuel Services (United States) ,
Belgonucléaire (Belgium), Framatome ANP through Framatome Cogéma Fuels
(France and Germany).
I.F.
Generation of electricity
In 2001, 103 reactors produced 753.9 billion kilowatt hours,
approximately 20% of US electricity. The total was 3.5% above the 1999
figure of 728.1 billion kilowatt hours.
The average net capacity factor in 2000 was 89.1%.[xxx]
All of the reactors are wholly or partly owned by US firms, but
the industry seems poised for change.
The joint venture
AmerGen Energy was formed by the US utility PECO[xxxi]
and the foreign entity British Energy to buy US nuclear power plants.[xxxii]
This venture is today a partnership in which the US utility
Exelon[xxxiii]
(formed by the merger of PECO and Unicom) and the foreign entity British
Energy each own 50%.
The Atomic Energy Act of
1954, as amended, and the NRC’s regulations in 10 CFR 50.38 make
foreign entities ineligible to apply for and obtain a license to operate
nuclear power plants. The
NRC staff evaluates license transfer applications that involve foreign
ownership by using the Final Standard Review Plan (SRP) on Foreign
Ownership, Control, or Domination, issued September 29, 1999.
In addition, the NRC must determine that a license or license
transfer “would not be inimical to the common defense and security of
the United States.” However,
apart from a prohibition on 100% ownership by a foreign entity, there is
no fixed percentage above which foreign ownership is strictly
prohibited.
When AmerGen sought a
license transfer that would enable it to operate Three Mile Island, Unit
1, the NRC, “Based on a
‘negation action plan’ developed pursuant to the SRP to mitigate
foreign ownership, control or domination . . . found that the foreign
partner did not control or dominate the safety-related decision making
related to the plant. Based on this assessment, the NRC was able to
approve AmerGen’s purchase of Three Mile Island, Unit 1, as well as
subsequent license transfers involving AmerGen,” the NRC states.[xxxiv]
The subsequent license
transfers through November 2001 have been for the Clinton and Oyster
Creek plants. AmerGen
failed in an attempt to purchase Vermont Yankee, because Vermont
regulators opposed the purchase and also did not succeed in acquiring
Nine Mile Point, because a single stockholder exercised his right to
veto.[xxxv]
The NRC states that it has analyzed proposals for license
transfers by entities other than AmerGen with some degree of foreign
involvement. “As industry
consolidation progresses, it is anticipated that there will be
additional situations in which foreign organizations seek to acquire
domestic nuclear power plants and domestic utility organizations. . . . Since 1999, the Commission has developed and submitted proposed
legislation that would remove restrictions on foreign ownership.
[italics ours] Senator Domenici has introduced in the current session of
Congress, S. 472, ‘Nuclear
Energy Electricity Assurance Act of 2001,’ which, among other things
would eliminate the foreign ownership restrictions for nuclear power
plants.” [xxxvi]
A look at non-nuclear power plants in the United
States gives an idea of what could be ahead for the nuclear sector if
the regulation on foreign ownership changes.
The British utility Powergen acquired Louisville Gas and Electric
(headquarters in Louisville, Kentucky) and Kentucky Utilities Company
(headquarters in Lexington, Kentucky).
Then in April 2001 the German company E.On AG offered to buy
Powergen; and Powergen accepted the offer.
If regulatory authorities in the United States and Europe agree,
Kentucky consumers will be served by the second-largest energy service
provider in the world.
The German utility group RWE AG is interested in
investing in US electricity suppliers and has not ruled out nuclear
plants.[xxxvii]
The Canadian Cameco Corp., which already owns uranium mines in
the United States, is also among the foreign companies interested in US
power plants. It is
considering investing in idle reactors or completing unfinished
facilities in the United States.[xxxviii]
I.G. Waste management
The major problem in regard to commercial nuclear waste is the
lack of means of disposing of the waste as safely as possible. The
problem is not limited to the widely publicized issue of what to do with
irradiated fuel. A
low-level waste crisis is in the offing. Foreign corporations with
experience in waste management are eager for US contracts, and one of
them has made a major contribution to the dissemination outside the
industry of contaminated metal. Below
we look briefly at the waste situation by type of waste as defined in
the United States.
I.G.1.High-level
waste (irradiated fuel, the products of reprocessing irradiated
fuel, and other high activity, long-lived waste from military
activities)
The 1982 Nuclear Waste Policy Act made DOE responsible for siting,
constructing, and operating a deep underground repository for irradiated
fuel and other high-level waste. The
agency was to complete construction of a repository and assume
responsibility for the fuel by February 1998.
It missed the deadline.
A 1987 amendment to the act directed DOE to examine
only one of the three sites that were under intensive scientific study
at the time, Yucca Mountain, Nevada.
(If DOE finds Yucca Mountain unsuitable, the agency must seek new
direction from Congress.) Opposition
to Yucca Mountain has been intense, with many people regarding
Congress’s choice as the result of politics rather than science.
DOE is expected to decide later in 2001 whether Yucca
Mountain is acceptable for a repository.
If DOE finds the site suitable, the NRC will have to determine
whether to license it. A repository at Yucca Mountain will not open
before 2010 at the earliest. Meanwhile, irradiated fuel is accumulating
in pools and in dry casks at reactor sites.
As of September 2000, about 42,000 metric tons of irradiated fuel
from nuclear power plants awaited a repository.
By 2035, the 42,000 tons from power plants could double, and an
additional 2,500 tons from research reactors, naval reactors, and
reactors to produce material for weapons may need disposal.[xxxix]
I.G.2.
Transuranic waste (waste
contaminated by transuranics, i.e., radioactive elements that are
heavier than uranium and extremely long-lived.)
Waste classed in the United States as
“transuranic” comes for the most part from Department of Defense and
Department of Energy programs. The
DOE’s Waste Isolation Pilot Project, a controversial waste disposal
site deep underground in a salt formation near Carlsbad, New Mexico, is
receiving “transuranic waste.”
Waste classed and handled as “low-level” is allowed to
contain some transuranics. [xl]
I.G.3.
Uranium mill tailings (waste
material produced by the milling and other processing of uranium ore to
concentrate the uranium)
Since
the uranium ore mined in the United States contains less than 1% uranium
by weight, essentially all of the treated ore ends up as tailings.
The tailings are normally heaped near the facility where they
were created. They
typically consist of a slurry containing “ground-up, sand- and
clay-size, waste-rock particles, most of [the] uranium-daughter
nuclides, and hazardous chemical residues.” Releasing gamma radiation
and radon among other substances, they can contaminate the water, air,
and soil.
Under the Uranium Mill Tailings Remedial Action Project, the
Department of Energy, in cooperation with states, Indian tribes, and
owners of specific sites, has carried out remediation activities on more
than twenty sites where uranium was milled from the early 1940s through
1970. The aim has been to
store the tailings, still normally near the point of production, in such
a way as to prevent further contamination of the environment, and to
clean up existing contamination. The
total cost of the program, as of December 31, 1999, was $1.48 billion.[xli]
Tailings piles are yet to be remediated at additional sites.
The 10.5 million tons of tailings dumped by the Atlas Corporation
mill on the Colorado River near Moab, Utah are a notorious example.[xlii]
I.G.4.
Low-level waste (essentially
all waste that is not classified as high-level or transuranic and does
not consist of uranium mill tailings, certain other by-product material
or weapons material)[xliii]
The 1980 Federal Low-Level Radioactive Waste Policy Act, as
modified in 1985, mandates that each state must take title to and
“provide for” the disposal of all “low-level” waste generated
within its boundaries. To
encourage development of disposal sites but limit their number, it
allows states that form waste disposal compacts to exclude from a
regional compact facility the “low-level” radioactive wastes
generated outside the compact region.
Most states have now entered into multi-state compacts.
However, none of the compacts has as yet created a waste disposal
site. Low-level waste is shipped to three privately-operated waste
disposal facilities: Chem-Nuclear’s
site at Barnwell, South Carolina; US Ecology’s site at Richland,
Washington (US Ecology is a subsidiary of American Ecology Corporation),
and Envirocare of Utah’s site in Utah.
Only one of the three sites, Barnwell, accepts all types of
low-level waste generated across the nation. Richland accepts low-level
waste only from the Rocky Mountain and Northwest Compact states.
Envirocare, because of the terms of its license, takes mainly
large-volume, low-activity waste such as soil and mill tailings. Such
waste is classified as Class A. The
waste classified as “Classes B and C” are more radioactive and tend
to contain isotopes with very long hazardous lives.
Barnwell, which accepts “B and C” waste will stop receiving
waste “from all but a handful of states” in 2008.
In 2000 South Carolina entered into an Atlantic Low-Level
Radioactive Waste Management Compact with Connecticut and New Jersey.
The South Carolina legislature closed Barnwell to waste from
states other than compact members as of 2008.[xliv]
The category of low-level waste includes
brooms and protective booties with a few hundred becquerels (Bq)
of radioactivity. It also includes ion exchange resins and cartridge
filters, used for purifying the water that circulates in a reactor and
in its irradiated fuel pool. The resins and filters are contaminated,
after use, with long-lived radionuclides, notably iodine129 and
plutonium 239. In addition,
low-level waste includes reactor components that have become highly
radioactive because of neutron bombardment within the reactor and also
the reactors themselves.
Since 1980, the NRC has tried to solve part of the low-level
waste problem by deregulating the less contaminated (but vast) portion
of this waste variously called by the authorities “de minimis”
(i.e., “trivial” waste), “Below Regulatory Concern,” and
“Incidental Radioactive Material.”
The agency wanted to allow this waste to be dumped into municipal
solid waste landfills and sewers or to be recycled into unlabeled
consumer products. The
Energy Policy Act of 1992 thwarted the agency’s initial deregulation
plan, but it has since been revised under various guises.[xlv]
At the present time the NRC, DOE, Department of Transportation,
and even the Environmental Protection Agency –in cooperation with the
International Atomic Energy Agency and European Union-- would like to
set a one millirem per year dose standard for deregulated low-level
radioactive waste, which would allow the release of a vast volume of
radioactive materials into the commercial marketplace for refabrication
into consumer products. DOT has finalized a rule
to “harmonize” at this dose level, transportation regulations
for radioactive materials in trans-boundary, international trade. The
NRC is, in late 2001, in the process of rulemaking in regard to waste
that it regards as very weakly radioactive and has hired the National
Academy of Sciences to provide recommendations on streamlining the
release of these
radioactive materials from regulatory control.[xlvi]
Furthermore, DOE is drawing up a Programmatic Environmental
Impact Statement on the Disposition of Scrap Metals.
The industry is particularly eager to establish standards that
allow release of contaminated materials, because of the enormous
quantities of so-called “slightly radioactive” material that will
need to be disposed of as nuclear facilities are cleaned up and
dismantled.
Around 700,000 metric tons of depleted uranium hexafluoride
stored in cylinders at the gaseous diffusion plants are among the wastes
that will be impacted by the new rule-making on release.
Depleted uranium hexafluoride is hazardous.
If it escapes into the atmosphere, it reacts with moisture in the
air to form hydrogen fluoride, a corrosive gas, and uranyl fluoride, a
soluble compound, toxic from both a chemical and a radiological point of
view. In 1998 Congress
enacted PL 105-204, mandating construction of two facilities to convert
the UF6 into a more stable solid. DOE
is, in 2001, in the process of selecting a contractor to build and
operate the plants and is compiling an environmental impact statement on
conversion. Whether the
depleted uranium, after conversion, is to be buried as waste, made into
containers for use within the nuclear industry, or incorporated into
items to be used outside the industry is still an open question.
Contaminated metal also poses a special problem
because of its volume. DOE
expects to generate a million tons of scrap metal in its complex as a
whole within the next twenty years as a result of decommissioning and
dismantling facilities. Much
of this waste will come from facilities that played a predominantly
military role. However,
the gaseous diffusion enrichment plants, because of their size, are a
major source of scrap. At
the present time the Paducah plant stores 54,000 tons of contaminated
scrap metal, more than any other facility in the DOE complex.[xlvii]
DOE contracted with British Nuclear Fuels Limited (BNFL) for the
decontamination and dismantling of the three process buildings at Oak
Ridge’s K-25 enrichment plant, a plant which had played a commercial
as well as a military role. The contract gave BNFL the right to
“recycle” some 126,000 tons of contaminated metal from the plant.
In 2000, then-secretary of energy Bill Richardson first suspended
release of certain volumetrically contaminated metal, notably nickel
that BNFL was disseminating, and then the release of any possibly
contaminated scrap from the entire DOE complex.
Richardson’s decision caused a subsidiary of BNFL,
Manufacturing Sciences Corp., to get out of the business of recycling
scrap.[xlviii]
When it comes to low-level waste, nuclear reactors are in a class
by themselves. Dismantling
the reactors will result in waste that can be released if a one-millirem-per
year dose standard goes into effect. However, it will also result in steel and concrete that is
more radioactive. No commercial-size reactor anywhere in the world has
been completely decontaminated and dismantled.
Andra, the French agency in charge of radioactive
waste, has estimated the
volume and radioactivity of the waste that will be produced by the
complete dismantling of the first pressurized water reactor constructed
in France, Chooz A. Chooz A
has undergone the initial stage of decommissioning and dismantling and
is now mothballed. The
reactor had a capacity of only 305 MWe, roughly one third the capacity
of a typical reactor operating in the United States today.
Today it contains what the French accurately call highly
radioactive waste (control bars, adapters, and test assemblies), also
diverse moderately active and “weakly” active waste (resin,
solvents, etc.) destined
for an above-ground disposal site.
In addition there are 5650 tons of contaminated or activated
metal (0.54EBq, contaminated with cobalt 60, iron 55, and nickel 63),
2000 200-liter drums of technological waste, and 1000 tons of activated
concrete. The volumetric
contamination of the most contaminated concrete is 1.35 TBq/m3.
The activity of the steel components of the reactor vessel is
0.17 EBq.[xlix]
I.H.
Academic infrastructure
A further indication of the lack of a viable domestic uranium
industry is the crumbling
of the academic infrastructure needed to maintain the nuclear industry.
An opinion piece by a friend of the industry in the Wall
Street Journal makes the point:
“Across the country, university programs in nuclear science and
engineering are seeing their funding cut, their faculty dispersed, their
laboratories padlocked. There
are already too few qualified nuclear engineers to meet current
demand.” “There are
roughly three positions for each recent graduate.”
If current trends continue, the situation will worsen.
“Most experts in the field, who entered the discipline in the
heroic early days of nuclear research, are now approaching retirement,
including three-quarters of the workforce in the national laboratory
system.”[l]
The Bush administration’s national energy bill, HR 4, reports
statistics: “Since 1980,
the number of nuclear engineering university programs has declined
nearly 40 percent, and over two-thirds of the faculty in these programs
are 45 years of age or older.”
Teaching reactors are closing. Twenty-eight
university reactors were functioning as of mid-2001, fewer than half the
reactors that were operating in the United States in the late sixties.[li]
Cornell University decided in May of 2001 to close its nuclear
teaching reactor. At
Columbia’s Ward Center for the Nuclear Sciences, the installation is
the last research reactor in New York state and the last in the Ivy
League. It will cease operating in 2001.
The University of Michigan made a decision in the fall of 2000 to
shut down its reactor.[lii]
The University of California at Irvine is considering closing its
reactor, although it is the only reactor on a University of California
campus in southern California..[liii]
The reactor operated only 98 hours during the fiscal year that
ended June 30, 2001. HR 4
notes that many of the existing reactors were built in the late 1950s
and 1960s, and “many will require relicensing in the next several
years.”
II.
WHAT WOULD IT TAKE TO REVIVE THE URANIUM INDUSTRY?
We can gain an idea of the initial payment needed to strengthen
the domestic industry, from legislation pending in Congress and from
additional steps under consideration by the Bush administration.
They include the following, arranged by industry sector:
II.A. Uranium mining
S 472, the Nuclear Energy Electricity Supply Assurance Act of
2001, and HR 4, the Bush administration’s energy bill, would authorize
expenditure of $10 million a year for three years to domestic
corporations to assist them in improving mining of uranium by in situ
leaching. (Lobbying against
this provision by Navajo residents of an area that was targeted for in
situ mining has reportedly caused Senator Pete Domenici and
Representative Heather Wilson, who introduced the mining provision, to
withdraw their support for it.[liv])
Limitations on the sale by DOE of uranium from its
inventory are proposed. S
472 would, with certain exceptions, prevent sale until 2006; HR 4, until
2009. (DOE’s uranium competes with newly mined uranium.).
II.B. Conversion
S 472 would grant DOE up to $8 million a year for FY
2002, 2003, and 2004 to be used to compensate ConverDyn for losses
incurred in providing conversion services, based on the difference
between ConverDyn’s costs and the price at which it can sell its
services. (The difference has recently narrowed.
See the section on Conversion in the first part of this report.)
HR 4 would grant DOE $800,000 “for contracting with
the Nation’s sole remaining uranium converter for the purpose of
performing research and development to improve the environmental and
economic performance” of US conversion operations.
II.C. Enrichment
For the Portsmouth Gaseous Diffusion Plant, S 472
would authorize $36 million for FY 2002 and “such sums as are
necessary for FY 2003, 2004, and 2005” to keep the plant in cold
standby for five years. (March
1 the Bush administration announced that the government would provide
$125.7 million for cold standby and worker transition--$59.2 million for
FY 2001 and $66.5 million for FY 2002.
The fate of the plant after September 30, 2002 was to be decided
by task forces. In April
the administration agreed to an extra $5 million for deposit
remediation. It should be
noted that much of the money for cold standby will go to heating the
three major process buildings and thirty-two other buildings.
Electric heaters were to be installed in the process buildings.)[lv]
As to the Paducah Gaseous Diffusion Plant, the
administration is reportedly considering subsidizing operations to keep
the plant functioning if USEC cannot afford to do so.
DOE may also be considering contributing financially
to the development of centrifuge enrichment technology.
(Congressman Ted Strickland tried to attach to HR4 in committee,
authorization for funding for this purpose; but was defeated by the Bush
administration, which was not ready to make a decision on the subject.)
Renewal of the Price Anderson Act (see below), which
would be authorized through the passage of any of several pieces of
legislation, would subsidize USEC, since USEC enjoys Price Anderson
protection. This protection saves it from having to try to buy liability
insurance and from the liability itself.
In the words of USEC just after
privatization, “DOE is required to indemnify USEC against
claims for public liability (1) arising out of or in connection with
activities under the Lease Agreement, including transportation and 2)
arising out of or resulting from a nuclear incident or precautionary
evacuation. DOE’s
obligations are capped at the $8.96 billion statutory limit set forth in
the Price-Anderson Act for each incident.”[lvi]
II.D.
Electricity production
S 472 would move the restriction on foreign ownership
of nuclear reactors imposed by the Atomic Energy Act.
(Foreign corporations may be more willing than US corporations to
invest in new nuclear plants.) It
also states, as one of the Findings of Congress, that the process of
licensing nuclear plants should be streamlined.
A Nuclear Generation Report that the US Nuclear Regulatory
Commission (NRC) is to submit to Congress within 180 days of passage of
the act is to include suggestions for improvements in the licensing
process.
In addition S 472 would authorize $50 million for FY
2002 and as much as necessary for FY 2003 through FY 2006 for research
relating to nuclear energy; $15 million for FY 2002 and as much as
necessary for FY 2003 through 2006 for a Nuclear Energy Plant
Optimization Program (a joint cost-sharing program with industry); $15
million each for FY 2002 and FY 2003 for fees incurred by licensees in
obtaining NRC approval for permanent increases in rated electricity
capacity; $3 million for FY 2002 for a study of the feasibility of
completing unfinished nuclear plants; $15 million for both FY 2002 and
FY 2003 for an early site permit demonstration program; $50 million for
FY 2002 and as much as needed for FY 2003 through 2006 for a report on a
new generation of nuclear reactors (Generation IV); and $25 million for
FY 2002 and as much as needed for subsequent years for research on the
regulatory process in relation to new types of reactors.
Several bills that
include reauthorization of the Price Anderson Act are pending in
Congress. The Act was first passed in 1957 as a means of subsidizing
the then-fledgling nuclear industry by lowering its insurance costs and
reducing its liability. It
is due to expire in August of 2002.
Price-Anderson requires that operators/owners of commercial
reactors obtain $200 million in insurance liability coverage per reactor
from private insurers. If
an accident that exceeds $200 million in damages occurs, all commercial
reactor operators in the United States must pay up to $88.095 million
per reactor towards the damages. Potential
payments by the entire commercial nuclear industry would be capped at
around $10 billion. (This
sum would likely prove far from adequate. In 1982 Sandia National
Laboratory calculated the financial cost of a severe accident, on behalf
of the NRC. The laboratory
estimated that damages could run as high as $314 billion--more than $560
billion in current dollars.)[lvii]
HR 4, as passed in the House, would ensure that all
companies that own nuclear power plants can deduct from their federal
taxes the money that they set aside to cover the cost of
decommissioning. At present
the tax break is assured only for companies with regulated rates.
The tax break is not automatically transferred when a plant is
purchased by a company without regulated rates.
The Internal Revenue Service has been granting the break on a
case by case basis as plants are bought.
The Congressional Joint Committee on Taxation estimates that the
proposed change, which would make the transfer automatic, along with
other changes related to decommissioning, would cost the federal
government $1.93 billion in revenue between 2002 and 2011.[lviii]
II.E. Waste management
S 472 would create an Office of Spent Nuclear Fuel
Research to study “treatment, recycling and disposal” of irradiated
fuel and other high-level waste. The
office will study advanced reprocessing, in particular.
For FY 2002, $10 million is to be allotted to development of
“advanced fuel recycling technology,” with money as needed in
FY 2003 through 2006. HR 4
authorizes funding for FY 2002 and for FY 2003 and FY 2004 on the same
subject.
II.F. Academic infrastructure
S 472 would authorize $34.2 million for fiscal year
(FY) 2002 and such sums as are necessary in future years to upgrade
university research reactors and to provide grants, fellowships, and
scholarships to students, faculty and staff associated with nuclear
engineering programs and related specialties. HR 4 would authorize $32.2
million for FY 2000 and increasingly larger sums for each of the next
four fiscal years to strengthen educational programs in nuclear
engineering and nuclear science through such means as research grants
for faculty, and fuel and instrumentation upgrades for reactors.
III.
WOULD
REVIVING THE INDUSTRY BE WORTHWHILE?
III.A.
A domestic industry is not needed as a source of fissile material
for weapons, as a source of energy, or even as an answer to global
warming
DOE currently has an inventory of approximately 73
million pounds of uranium. This
inventory is made up of 15 million pounds contained in 33 tons of HEU
that DOE has committed to the Tennessee Valley Authority for
downblending into fuel and 58 million pounds that are to be stockpiled
until 2009 as part of an agreement relating to the Russian HEU
agreement. The stockpiled
uranium includes 5.9 million pounds contained in 10 tons of HEU that DOE
holds under IAEA safeguards.[lix]
DOE will obtain additional HEU through the dismantling of nuclear
weapons, as President Bush plans to reduce greatly the size of the US
strategic arsenal. The
United States is therefore not dependent for new weapons or naval fuel
on enriching natural uranium.
Nuclear power plants furnished 19.8% of US
electricity in 2000; but less than 9% of the total energy we consume.
The energy from these plants could be replaced.
In developing a Clean Energy Blueprint, the Union of
Concerned Scientists found that the United States can meet at least
twenty percent of its electricity needs through renewable energy
sources—wind, biomass, geothermal, and solar-by 2020.[lx]
Nuclear power can also be replaced by energy
efficiency. Amory B. Lovins
and L. Hunter Lovins of the Rocky Mountain Institute report that
electricity efficiency alone “can save four times’ nuclear power’s
output.”[lxi]
Gains in energy efficiency would not require complex technology,
the Lovinses say, simply good basic engineering.
The energy spent on pumping, for instance, the main application
of motors, could be decreased by reducing friction through increasing
the diameter, shortening the length, and eliminating the bends in
piping. Energy managers
would need to think in terms of meeting peoples’ specific needs rather
than in terms of delivering a certain number of kilowatts.
Thus a need for cooling could be met, at least in part, by
planting trees and shrubbery and installing light-colored roofing and
sidewalks rather than by powering air conditioners.
Conservation can also help; but to many people
conservation implies deprivation, and, if sufficient energy efficiency
measures are implemented, deprivation will not be necessary. Bill Prindle, Director of Buildings and Utilities Programs at
The Alliance to Save Energy, explains the difference between energy
efficiency and conservation with a series of graphic examples, the first
of which is: “Conservation
means sitting in the dark. Efficiency
means installing lights that use one-fourth the energy, and letting an
automatic sensor turn them off when you leave.
If each household in the U.S. replaced four 100-watt bulbs with
compact fluorescents, we would save the energy output of thirty 300-MW
power plants,”[lxii]
or about ten average size US nuclear power plants.
That energy efficiency and conservation can bring
about dramatic changes in consumption is illustrated by California.
California, before its deregulation crisis, was the nation’s
second most efficient state in the use of energy.
Because of the crisis, the state reduced its consumption of
energy by an additional 15%, which helped it avoid the large-scale power
cuts predicted for the past summer.[lxiii]
Energy gains through renewables and energy efficiency
cost less than gains through construction of new nuclear power plants.
To quote the Lovinses:
Enthusiasts claim hypothetical new reactors might
deliver a kilowatt-hour for 6 cents vs. 10+cents for post-1980 plants.
(Nearly 3 cents pays for delivery to customers.)
But super-efficient gas plants or wind farms cost 5-6 cents;
co-generation of heat and power often 1-5 cents
The cost of saving a
kilowatt-hour through efficient lights, motors and other
electricity-saving devices is under 2 cents;
and they’re all getting cheaper.
So are the next winners: fuel
cells and solar cells. . . .[lxiv]
An
editorial in British newspaper The
Guardian, November 10 notes:
The main argument against nuclear power is
not safety. It is cost. . .
The latest Cabinet Office figures suggest that by 2020 onshore wind
farms will generate energy at 1.5p to 2.5p per kilowatt hour, offshore
wind at 2p to 4p while nuclear will be 3p to 4.5p without including the
costs of terrorism or the unsolved problem of waste disposal. . . . If 60% of the . . . cost
of building six nuclear stations was spent instead on alternatives like
wind, wave, solar, fuel cell, photovoltaics and massive conservation
measures, it is highly unlikely, there would be any need for a nuclear
option.
Furthermore, as a Department of Energy working group
has made clear, we do not need nuclear energy in order to cut back on
greenhouse gas emissions. The
Interlaboratory Working Group on Energy-Efficient and Clean-Energy
Technologies demonstrates in Scenarios
for a Clean Energy Future that use of renewable energy and energy
efficiency options could, by 2020, reduce fossil fuel use by 21 percent
and cut climate-changing emissions by 31 percent while shrinking the
United States’ total energy bill by 18 percent.[lxv]
According to Amory Lovins, a dollar invested in
energy efficiency produces roughly double the reduction in greenhouse
gases than a dollar invested in the nuclear industry does. Since a dollar can be spent only once, investments in nuclear
energy thus actually impede reduction of the greenhouse effect.[lxvi]
III.B.
The industry detracts from the nation’s security
The nuclear industry has a negative impact on the nation in
varied ways, from the effects of uranium mining on health and the
environment, to the example that our industry sets to developing
countries. Here we look
briefly at three aspects of the impact, related too the possibility of
nuclear terrorism.
Nuclear power plants and their stocks of irradiated fuel are a
liability due to their potential for releasing massive amounts of
radioactivity. During operation of a reactor, fission products and
transuranics, including plutonium, build up in the reactor fuel.
As a result, the fuel becomes highly radioactive and also
literally hot. The melting of a reactor core releases radiation into the
air, with the amount of radiation varying with the length of time that
the fuel has been in the reactor. Sandia National Laboratory examined
for the NRC the consequences of a severe nuclear accident at each US
plant. Their statistics
include fatalities that occur within one year.
Salem 1 and 2, south of Wilmington, Delaware, had the greatest
estimated number--100,000 fatalities.[lxvii]
A release could be triggered by an accident, as at Chernobyl.
It could also be triggered by terrorists. Since September 11,
David Kyd, spokesperson for the International Atomic Energy Agency has
admitted that “The West’s reliance on electricity, much of it from
nuclear sources, is such that a nuclear plant would be a potential weak
point for terrorists to pick out.”[lxviii]
Both the IAEA and the NRC, responding to questions from the public, have
stated that plant containment structures were not built to withstand
attacks by airliners such as Boeing 757s or 767s.[lxix]
The media have relayed reports of al-Qaida’s interest in
nuclear terrorism; and the actions of governments at various levels have
underlined the fact that the terrorist threat is real.
Security measures for US plants, though insufficient, have
included patrols by the National Guard and the Coast Guard, the closing
of roads, and a moratorium on flights by general aviation near specified
nuclear sites.
In regard to terrorism, an even greater danger than the reactor
itself may be the pools of water
in which utilities store irradiated fuel that they have removed from
their reactors. The pools
at US plants are always in buildings that are outside the reactor’s
containment structure. The
buildings are designed to resist earthquakes but not to withstand
explosions or impacts from airplanes. Furthermore, they contain many
times as much radioactivity as the reactor core.[lxx]
The water in storage pools must be continuously cooled.
If cooling stops, the water in the pool heats up and boils. If
the water boils or if it simply drains away, the irradiated fuel
assemblies will overheat and either melt or catch fire, with
catastrophic consequences.
When fuel storage pools become full, utilities store fuel in dry
casks. The casks are
generally a more secure means of storing fuel than pools, because they
rely on passive cooling by radiation and air convection rather than on
active cooling by water and pumps.[lxxi]
However, at some plants the dry casks are “line-of-sight
visible” from open areas or inside unguarded chain link fences.
According to the Union of Concerned Scientists, explosives or weapons
that are available on the black market or, in some cases, available
legally inside the United States could “cause the casks to be
penetrated resulting in the release of large amounts of radiation.”[lxxii]
The Energy Information Administration has removed from its Web
site the quantities of irradiated fuel at each nuclear plant, tacit
admission that the stored fuel poses a problem.
Nuclear power plants are a liability also in terms of the
nation’s energy supply, as they are major components of centralized
systems of electricity production and distribution.
One nuclear power plant’s being off line can affect the
electricity supply of a large area. In fact, the unavailability of the San Onofre-3 reactor after
a fire February 3 was a
factor in the California energy crisis.[lxxiii]
Furthermore, the sabotage of key transmission lines
could prevent the electricity from nuclear plants that are operating
from reaching consumers. As
journalist has summarized, “thousands of miles of high-voltage lines
crisscross America. Attacks on key lines could trigger vast power
outages because grids are widely interconnected.”[lxxiv]
Severe weather, which is becoming increasingly common
as global warming proceeds, can also wreck havoc on transmission
systems. The ice storm in Quebec and the northeastern United States in
1998 and the wind storm in France in late 2000 strikingly illustrate the
problem. In France some
areas were without electricity service for more than a month.
The problem of nuclear waste also makes the nuclear industry a
liability. Here we discuss
irradiated fuel. At the same time that the Bush administration is
supporting construction of a deep underground repository at Yucca
Mountain, a location that is highly questionable from the standpoint of
geology, it is advocating recycling. Legislation in Congress would
create an Office of Spent Nuclear Fuel Research, to study this subject
in particular. In reference
to irradiated fuel, recycling involves what is called reprocessing,
treating irradiated fuel to separate the constituents.
Plutonium is one of the constituents that is separated out.
Thus reprocessing increases the risk of nuclear proliferation.
The United States currently has more than 40,000 metric tons of
irradiated heavy metal, stored in pools at reactor sites.[lxxv]
Had this fuel been reprocessed, the US would have produced some
400 tons of separated plutonium.
Industrial facilities today use the wet, Purex method
of reprocessing, in which chopped up fuel is dissolved in nitric acid.
France and the United Kingdom, which operate the La Hague and Sellafield
reprocessing plants respectively, are both edging away from
reprocessing. France has
admitted that it does not intend to reprocess all the irradiated fuel
that its electricity utility EDF discharges.
The French Atomic Energy Commission has, in fact, begun research
on centralized above-ground or near-surface facilities for long-term
storage of irradiated fuel.[lxxvi]
Furthermore, by stationing anti-aircraft batteries to protect the
La Hague reprocessing site, the French government has admitted that
terrorists could cause a catastrophic release of radioactivity from the
site. In the United
Kingdom, the electricity utility British Energy has announced that for
economic reasons it does not want to reprocess its fuel any longer.
Irish political leaders, afraid of the contamination spread by the plant
during its normal operation and of the results of a terrorist attack
have called for the plant to be shut down.
The Bush administration’s energy policy proposes
that the United States develop and deploy a dry process known as “pyroprocessing.”
The fuel is chopped up and dipped in baskets into molten salt
through which an electric current is passing.
Most of the components of the fuel dissolve.
Some remain in the salt; uranium and plutonium collect on
different cathodes and are removed.
Proponents of the process say that it is proliferation proof,
because the plutonium that is retrieved is contaminated with some
uranium, other transuranic elements, and some fission products; but the
contamination is not such as to prevent terrorists from using the
plutonium in a nuclear device; and the process can be altered to
separate out pure plutonium.[lxxvii]
The Bush energy policy also talks about combining
pyroprocessing with what is called Accelerator Transmutation of Waste.
The aim of transmutation is to transform specific isotopes,
removed from the waste by one or more separation techniques, into
isotopes that are stable or short-lived.
The transmutation occurs when neutrons bombard the target isotope(s).
Bombardment takes place in a reactor, preferably a breeder or a
subcritical reactor, the latter combined with an accelerator-driven
spallation neutron source to form a hybrid system.
Some long-lived radionuclides cannot be so transformed.
Among them are carbon 14, strontium 90, uranium 238 and cesium
135. Certain radionuclides
that can be transmuted must pass through a reactor several times and be
subject to several bouts of advanced reprocessing between each passage.
Scenarios involving transmutation on a major scale require parks of
nuclear reactors, and specialized installations to manufacture reactor
fuel and to reprocess irradiated fuel.
They also demand long periods of time.[lxxviii]
A 1999 DOE report to Congress, “A Roadmap for Developing ATW
Technology” described the transmutation of the US irradiated fuel
inventory over 118 years at a cost of $279 billion. |
