Brave nuclear world? The planet is warming, and proponents of nuclear power say they've got the answer. Are nuclear plants the climate cavalry? First of two parts.

When decommissioning is completed by the end of the year, over 136,000 metric tons of soil, concrete, metal, and other materials will have been removed from the site at a cost of more than US$400 million to the area's electricity customers.
But for a fluke in timing, Connecticut Yankee might well have remained in operation today. Ten years ago, when the board of directors of the Connecticut Yankee Atomic Power Company decided to close its reactor at Haddam Neck, nuclear power was widely considered, if not a dying industry, then one that was seriously and chronically ill. In the newly deregulated electricity market, the company found it could buy electricity for less than its nuclear power plant could produce it. Connecticut's deregulation Deregulation

Traditional areas that have been deregulated are the telephone and airline industries. of the electricity sector required the company to divest itself of the plant. Company directors didn't think they could sell a single reactor of relatively low capacity, so they decided to shut it down.
Just a few years later, the economic landscape for nuclear power began changing with the emergence of companies like Exelon Corporation (a merger between Chicago-based Commonwealth Edison This article is about ComEd in Illinois. For ConEd in New York, see Consolidated Edison.

Less than 80 kilometers south of Connecticut Yankee, Dominion Resources Dominion NYSE: D (formerly Dominion Resources) is a power and energy company headquartered in Richmond, Virginia, USA, that supplies electricity, natural gas, or other energy services to homes in Virginia, West Virginia, Ohio, Pennsylvania, and eastern North Carolina. spent US$1.3 billion to acquire three reactors (two operating and one shut) at Millstone--a plant with the dubious distinction of landing on the cover of Time in 1996 for longstanding, egregious breaches of safety regulations. By 2002, just 10 corporations owned all or part of 70 of the nation's 103 operating reactors.
Fast forward to today. The world has begun to wake up to the very real and growing perils of human-induced, catastrophic climate change. The war in Iraq, increasing tension in the oil-rich Middle East, and memories of both the (market-manipulated) energy fiasco in California in 2001 and the blackout that affected one-third of the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America.

(IAEA IAEA International Atomic Energy Agency. ), nine new nuclear plants--three in Japan, two in Ukraine, and one each in South Korea, India, China, and Russia--have gone online since 2004. In that time, two plants in Canada were restarted after years of not operating, and there is talk of building a new reactor there. Currently 23 nuclear power plants are under construction around the world, including one in Finland, the first in western Europe since the 1986 explosion at Chornobyl in northern Ukraine. France, whose 58 reactors provide approximately 80 percent of that country's electricity, is also considering building another reactor, and British Prime Minister Tony Blair is calling for new reactors to replace Britain's aging fleet of 31 reactors, most of which are due to retire by 2020. In August 2005, U.S. President George W. Bush signed into law an energy bill that contained US$13 billion in public subsidies to help jumpstart a new generation of nuclear reactors.
Nuclear Power vs. Global Warming
A growing chorus of nuclear advocates, government officials, international bureaucrats, academics, economists, and journalists is calling for nuclear power to save us from devastating dev·as·tate

Nuclear reactors do not emit carbon dioxide carbon dioxide, chemical compound, CO2, a colorless, odorless, tasteless gas that is about one and one-half times as dense as air under ordinary conditions of temperature and pressure. (C[O.sub.2]) and other greenhouse gases when they split atoms to create electricity. But it's inaccurate to say that nuclear power is "carbon-free"--on a cradle-to-grave basis, no currently available energy source is. (Even wind turbines are guilty by association: the aluminum from which they are built is often smelted using coal-fired electricity.) In the case of nuclear power, fossil fuel energy is used in the rest of the nuclear fuel chain--the mining, milling, and enriching of uranium for use as fuel in reactors, the building of nuclear plants (especially the cement), the decommissioning of the plants, the construction of storage facilities, and the transportation and storage of the waste. In fact, the gaseous diffusion uranium enrichment plant at Paducah, Kentucky, is one of the single biggest consumers of dirty coal-fired electricity in the country.
Still, it seems impossible to pin down exactly how carbon-intensive the nuclear fuel chain is, and there is disagreement within the environmental community about nuclear energy's potential contribution to global warming. Tom Cochrane, a nuclear physicist with the Natural Resources Defense Council The Natural Resources Defense Council (NRDC) is a New York City-based, non-profit non-partisan international environmental advocacy group, with offices in Washington, D.C., San Francisco, Los Angeles, Chicago, and Beijing. Founded in 1970, NRDC today has 1. , says nuclear power is not a large greenhouse gas emitter compared to other conventional sources of energy. But in order for nuclear energy to make a significant dent in greenhouse gas emissions, we would need a huge increase in the number of nuclear power plants now operating worldwide, which he does not support.
Just how huge? A widely quoted 2003 report by Massachusetts Institute of Technology Massachusetts Institute of Technology, at Cambridge; coeducational; chartered 1861, opened 1865 in Boston, moved 1916. It has long been recognized as an outstanding technological institute and its Sloan School of Management has notable programs in business, researchers, "The Future of Nuclear Power," calls for the construction worldwide of 1,000-1,500 new 1,000-megawatt reactors by 2050, an expansion that would potentially displace 15-25 percent of the anticipated growth in carbon emissions from electricity generation projected over that time. A 2004 analysis in Science by Stephen Pacala and Robert Socolow, co-directors of Princeton University's Carbon Mitigation Initiative, says 700 gigawatts of new nuclear generation--roughly double the number and output of the world's 443 operating reactors--would be needed to achieve just one-seventh of the greenhouse gas emission reductions (at current emission rates) required to stabilize atmospheric carbon concentrations at 500 parts per million parts per million
mg/kg or ml/l; see ppm. (ppm).
The MIT MIT - Massachusetts Institute of Technology report acknowledges such an expansion would create an enormous nuclear waste challenge requiring a permanent disposal site with the capacity of the proposed repository at Yucca Mountain in Nevada "to be created somewhere in the world every three to four years." If the spent fuel were reprocessed instead, as many nuclear proponents advocate, it would dramatically increase opportunities to spread nuclear material that could be used in making atomic bombs. The MIT report rejects reprocessing Reprocessing may refer to:

b. ignored the difficult politics of nuclear energy.
Pacala and Socolow maintain that a range of options is needed to address climate change. They identify 15 technologies or practices now in commercial operation somewhere in the world and say that scaling up any seven of them could stabilize carbon emissions over the next 50 years. These alternatives will be more fully explored in Part II of this series.
"Nuclear Follies," a February 11, 1985 cover story in Forbes, declared the United States' experience with nuclear power "the largest managerial disaster in business history." With US$125 billion invested, the magazine wrote, "only the blind, or the biased, can now think that most of that money has been well spent. It is a defeat for the U.S. consumer and for the competitiveness of U.S. industry, for the utilities that undertook the program and for the private enterprise system that made it possible."
Yet nuclear power is now widely promoted as one of the most economical sources of electricity, with a production cost of 1.68 cents per kilowatthour (kWh), compared to 1.9 cents/kWh for coal, 5.87 cents/kWh for natural gas, 2.48 cents/kWh for solar, 0.2 cents/kWh for wind, and 0.5 cents/kWh for hydroelectric, according to the Electric Utility Cost Group, a data group within the nuclear industry that draws its information from plant surveys, and Global Energy Decisions, a private energy data consulting firm. Those figures measure the operating cost of fuel, labor, materials, and services to produce one kWh of electricity. But like most sources of energy, nuclear power benefits from substantial government subsidies. Including nuclear's subsidies, collateral costs, and externalities externalities
side-effects, either harmful or beneficial, borne by those not directly involved in the production of a commodity. leads to a different economic assessment.*
Although a full nuclear revival with a new generation of reactors to replace the existing fleet could not take place--at least in the United States--without the participation of the private sector, commercial nuclear power has never had to compete in a true free market. From the beginning, nuclear power worldwide has always required government patronage. In the United States, the industry was launched in 1946 with the passage of legislation creating the Atomic Energy Commission Atomic Energy Commission (AEC), former U.S. government commission created by the Atomic Energy Act of 1946 and charged with the development and control of the U.S. atomic energy program following World War II. (the predecessor to the Nuclear Regulatory Commission Nuclear Regulatory Commission (NRC), an independent U.S. government commission, created by the Energy Reorganization Act of 1974 and charged with licensing and regulating civilian use of nuclear energy to protect the public and the environment. , or the NRC NRC

2. Nuclear Regulatory Commission
Noun 1. NRC - an independent federal agency created in 1974 to license and regulate nuclear power plants ), which was charged with developing both civilian nuclear power and nuclear weapons. In 1954 the government brought the private sector in, and under President Dwight D. Eisenhower's "Atoms for Peace "Atoms for Peace" was the title of a speech delivered by Dwight D. Eisenhower to the UN General Assembly in New York City on December 8, 1953.
The United States then launched an "Atoms for Peace" program that supplied equipment and information to schools, hospitals, and " initiative continued to encourage the development and commercialization of nuclear power.
Although nuclear power currently provides about 20 percent of U.S. electricity (and about 16 percent of the world's), between 1950 and 1993 the U.S. nuclear power industry received nearly 50 percent of the total federal spending on energy research and development--some US$51 billion--according to energy economist Doug Koplow. Substantial government assistance appears to be the status quo [Latin, The existing state of things at any given date.] Status quo ante bellum means the state of things before the war. The status quo to be preserved by a preliminary injunction is the last actual, peaceable, uncontested status which preceded the pending controversy. for the nuclear industry around the world, he adds, though specific data from many countries is unavailable. Nuclear power continues to get favored treatment, with government assistance covering virtually all segments of the nuclear fuel chain to one degree or another.
Uranium mining companies operating in the United States, for example, get a "percentage depletion percentage depletion
Depletion calculated as a percentage of gross income derived from a natural resource. Percentage depletion is independent of the cost of the resource. allowance" of 22 percent (the highest rate of all depletion allowances for minerals), which gives them a tax write-off for the market value of what they have extracted--a significant subsidy since the write-off is typically much greater than their actual investment. The manufacture of the reactor fuel has also been heavily subsidized. Until 1998, the government owned the country's two uranium enrichment plants. When they were privatized into the U.S. Enrichment Corporation, the government retained liability for the waste clean-up associated with the operation of the facilities, an ongoing endeavor with a price tag in the billions.
During construction of the reactors, utilities were able to pass on the interest costs of the loans to their electricity customers, utilizing the "Allowance for Funds Used During Construction." While this was available to all types of power plants, Koplow says it mainly benefited owners of nuclear plants, because costs on the already expensive plants ran out of control with construction delays. Nuclear plant owners also took advantage of highly accelerated depreciation Accelerated Depreciation

The straight-line depreciation method spreads the cost evenly over the life of an asset. and investment tax credits in the early 1980s. Koplow says these three accounting mechanisms significantly reduced the capital costs of the reactors. Even so, after states began deregulating de·reg·u·late

State after state changed the rules to allow utilities to pass on these stranded costs to ratepayers as a surcharge on their electric bills, a gift to the nuclear industry that by 1997 was worth some US$98 billion.
The ratepaying public also bears the cost of dealing with the spent fuel--estimated at US$60-100 billion for the existing fleet of reactors--as well as for decommissioning the plants. And if there is another serious accident, the 1957 Price-Anderson Act shields nuclear plant owners from the lion's share of the cost by capping their liability. According to Koplow, the utility responsible for the accident would pay US$300 million in primary liability plus US$95.8 million that it and the nation's other nuclear utilities would contribute per reactor (paid in US$15-million annual installments over six years) to an insurance pool. With 103 operating U.S. reactors, the size of the insurance pool is approximately US$10 billion. By comparison, some estimates put the cost of the Chornobyl accident at over US$350 billion, and the Union of Concerned Scientists The Union of Concerned Scientists (UCS) is a nonprofit advocacy group based in Cambridge, Massachusetts, United States. The UCS membership includes many private citizens in addition to professional scientists. estimates that a serious accident at New York's Indian Point plant 56 kilometers north of New York City New York City: see New York, city.

The largest city in the U.S. would be in the trillions--costs mainly left to individuals because of the standard nuclear exclusion clause in home insurance policies. Without this particular liability mitigator in the United States and similar instruments in other countries, commercial nuclear power probably would not exist.
Moreover, it seems that Price-Anderson is not the only mechanism available to nuclear utilities to protect themselves from full liability if something goes wrong. According to a 2002 report by Synapse synapse (sĭn`ăps), junction between various signal-transmitter cells, either between two neurons or between a neuron and a muscle or gland. A nerve impulse reaches the synapse through the axon, or transmitting end, of a nerve cell, or neuron. Energy Economics, Inc., since the restructuring of the U.S. nuclear industry began as states started deregulating their electric utility industries in the mid-1990s, a few large corporations such as Exelon Corp., Entergy Corp., Duke Energy, and Dominion Resources, Inc. increasingly own and operate nuclear power plants through multi-tiered holding companies. The individual plants are often set up as limited liability companies (LLCs), a legal invention that restricts liability to the assets directly owned by the LLC (Logical Link Control) See "LANs" under data link protocol.
LLC - Logical Link Control . "The limited liability structures being utilized are effective mechanisms for transferring profits to the parent/owner while avoiding tax payments," the report notes. "They also provide a financial shield for the parent/owner if an accident, equipment failure, safety upgrade, or unusual maintenance need at one particular plant creates a large, unanticipated cost. The parent/owner can walk away by declaring bankruptcy for that separate entity without jeopardizing its other nuclear and non-nuclear investments."
This arrangement is especially valuable under deregulation. Before deregulation, nuclear reactors typically were built by investor-owned utilities and operated under the shelter of a "cost-of-service regulation." This enabled the utilities to enjoy stable rates based on their actual costs rather than on electricity sales at market prices, which can fluctuate. With those stable rates stripped away, the usual risks of operating nuclear plants--unexpected shutdowns for nonscheduled non·sched·uled
Operating without a regular schedule of passenger or cargo flights: a nonscheduled airline. maintenance, for instance, or even accidents--became more severe. The use of LLCs allowed much of that risk to be avoided. Yet, according to former NRC commissioner Peter Bradford, the agency failed to develop a comprehensive policy to ensure that the transfer of reactor ownership into these new corporate structures would not endanger the public. "In the absence of any such requirement, public protection has depended on the acumen of a Nuclear Regulatory Commission unversed in financial matters and of economic regulators unversed in health and safety issues. As has happened in financial and in utility restructuring circles, fundamental safeguards have been circumvented," he writes in the forward to the Synapse report. The consequences, he adds, remain to play out.
The NRC rejects both Synapse's and Bradford's allegations. In a written statement, the agency said it believes its regulations "provide reasonable assurance that a licensee will have sufficient resources to operate, maintain, and decommission de·com·mis·sion

The NRC fully considered the issues raised in the 2002 Synapse report and believed then--and continues to believe--that our regulations adequately address LLCs or other corporate arrangements." The agency maintains that regardless of the new business arrangements, it continues to ensure that reactor owners meet their obligations, adding that most reactors also operate under regulation by state public utility commissions, which provide significant financial oversight.
"Their general platitudes don't convince me that we were wrong on any issue," says David Schlissel, lead author on the Synapse report. In addition, he says NRC is incorrect that state public utility commissions continue to oversee reactors in states where electricity markets have been deregulated. "The 19 plants owned by Exelon, they are all deregulated," he says, "as are many nuclear plants in the Northeast and Midwest."
Try, Try Again
On Valentine's Day in 2002, the U.S. Department of Energy unveiled its Nuclear Power 2010 program The "Nuclear Power 2010 Program" was unveiled by the U.S. Secretary of Energy Spencer Abraham on February 14, 2002 as one means towards addressing the expected need for new power plants. for sharing costs with industry to "identify sites for new nuclear power plants, develop and bring to market advanced nuclear plant technologies, evaluate the business case for building new nuclear power plants, and demonstrate untested regulatory processes leading to an industry decision in the next few years to seek NRC approval to build and operate at least one new advanced nuclear power plant in the United States." Currently three consortia, an 11-company group called NuStart Energy Development and smaller ones led by the Tennessee Valley Authority Tennessee Valley Authority (TVA), independent U.S. government corporate agency, created in 1933 by act of Congress; it is responsible for the integrated development of the Tennessee River basin. and Dominion Resources, have been formed to investigate building new reactors. Despite consortia members' combined revenues of US$447 billion during 2003--which, Koplow points out, rivals the Russian Federation and exceeds the combined GDP GDP (guanosine diphosphate): see guanine. of 104 countries--the U.S. government is now offering the nuclear industry additional incentives worth more than US$13 billion as seed money for new nuclear plant construction. According to an analysis released last year by the non-profit group Public Citizen, the Energy Policy Act of 2005 includes US$2.9 billion for R & D, at least US$3.5 billion worth of construction subsidies, more than US$5.7 billion for operating subsidies, and US$1.3 billion for shutdown subsidies.
Some of the package's more notable elements include US$2 billion for risk insurance, which allows builders of the first six reactors to collect for any delays in construction or licensing, including challenges by the public on safety grounds (e.g., if a whistleblower whis·tle·blow·er or whis·tle-blow·er or whistle blower
One who reveals wrongdoing within an organization to the public or to those in positions of authority: "The Pentagon's most famous whistleblower is . . reported faulty construction and a citizen group sued). It includes production tax credits of 1.8 cents per kilowatthour for eight years, an estimated US$5.7-7.0 billion that would otherwise go to the U.S. Treasury U.S. Treasury
Created in 1798, the United States Department of the Treasury is the government (Cabinet) department responsible for issuing all Treasury bonds, notes and bills. Some of the government branches operating under the U.S. Treasury umbrella include the IRS, U.S. . There are also provisions for taxpayer-backed loan guarantees for up to 80 percent of the cost of a reactor. These loan guarantees are particularly handy, considering that billions of dollars were lost during the first round of nuclear plant construction when more reactors were cancelled than were built, many after hundreds of millions of dollars had already been spent.
That's a big handout, but it remains to be seen whether it's enough to kick-start a new generation of reactors in the United States, which industry observers say is necessary for a viable economic future for nuclear power. Thomas Capps, the recently retired CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of Dominion Resources, head of one of the consortia seeking a license for a new reactor, told the New York New York, state, United States

It is bordered by Vermont, Massachusetts, Connecticut, and the Atlantic Ocean (E), New Jersey and Pennsylvania (S), Lakes Erie and Ontario and the Canadian province of Times last April that if his company announced it was actually going to build a nuclear plant, debt-rating agencies Standard & Poor's and Moody's "would have a heart attack, and my chief financial officer would, too." Peter Wells, general manager of marketing for General Electric's nuclear energy division, is cautiously optimistic but not yet convinced a new generation of reactors will be built. He says it will depend on friendly government policy and positive experience with the first of the new reactors coming in within budget and on schedule.
Bush Administration policy is increasingly agreeable to the nuclear industry, but whether reactors can be built for their advertised costs is another question. At US$1,500 per kilowatt, the new "advanced" Generation III+ reactors are said to be much cheaper than those in the existing fleet. According to a 2001 Congressional Research Service The Congressional Research Service (CRS) is a branch of the Library of Congress that provides objective, nonpartisan research, analysis, and information to assist Congress in its legislative, oversight, and representative functions.

mis·cal of costs has been a longtime problem with large engineering projects, and the nuclear power industry is no exception. According to an analysis by the Energy Information Administration, plants that began construction between 1966 and 1977 underestimated their actual costs by roughly 14 percent, even when plants were 90 percent complete.
So far, only two reactors of new design, both of them GE Advanced Boiling Water Reactors, have been built (in Japan, for the Tokyo Electric Power Company). However, despite GE's estimate that the cost would be US$1,528/kw, CRS reports the first came in at US$3,236/kw and the second at around US$2,800/kw. Wells says the price of those plants was inflated because they were "gold-plate plants with marble floors and the like" that otherwise would have cost much less.
Peter Bradford says that despite the passage of the Energy Policy Act, nothing has fundamentally changed that would improve the economics enough to see a new generation of nuclear reactors. "With US$13 billion in new subsidies, if the government wants to prove that if it spends enough it can build nuclear plants, it can do that. The Chinese prove that for us a couple times a year," he said. "But that's not the same as saying it makes economic sense to do it." Still, Bradford acknowledges, "the stars have not been so favorably aligned for the industry since Atoms for Peace."
In a dramatic turnaround from nuclear's dog days in the 1980s and '90s, excitement is building on Wall Street. Steven Taub, director of emerging technologies at Cambridge Energy Research Associates Cambridge Energy Research Associates, also known as CERA, is a consulting company that specializes in advising governments and private companies on energy markets, geopolitics, industry trends, and strategy. , is confident new plants will be built, though he says the exact number will depend on how the various government incentives are distributed. Unlike the current fleet of nuclear reactors--nearly all of which were custom built--the next generation will be much more standardized to take advantage of economies of scale.
The government subsidies for new reactors are intended to offset the higher "first-of-a-kind" costs for the first few plants. If all goes without a hitch, the thinking is that lenders and utility shareholders will regain confidence that new nuclear plants can be competitive enough to finance without these subsidies. External factors will also determine the competitiveness and economic viability of nuclear power, Taub says. These variables include the price of natural gas, whether a carbon tax or other price-raising measures will be imposed on coal and other fossil fuels, and whether carbon sequestration sequestration

"These are questions that nobody knows the answer to," he says.
Part II of this series will look at the waste problem, the proliferation and other security risks stemming from nuclear power, and at the strength of arguments for nuclear power in the context of other options.
