Nuclear Power Worthy of Public Investment

Issue 10 and Volume 107.

There are significant difficulties in rejuvenating the U.S. nuclear power industry. With an energy bill moving to the front burner in Congress, however, a next wave of safe, reliable “Generation III” plants could be brought on-line after 2010, just as more than 100,000 MW of less efficient coal plants approach retirement age.

According to the American Nuclear Society and other sources, public opinion polls have turned around on nuclear power, with 60-70% of the American public favorably disposed toward the clean power provided by nuclear reactors. As former FERC commissioner Branko Terzic put it at the Deloitte Energy Conference recently, “Nuclear power offers reliable, high quality, emission-free electricity at stable prices not dependent on weather, close to loads with a small footprint — from a planning viewpoint, what’s not to like!”

Further, the Nuclear Regulatory Commission has renewed licenses on 16 reactors at eight sites in seven different states. The veracity of anti-nuclear groups is frankly overestimated: many observers predicted complicated license renewal of the current reactors with public opposition and lawsuits. Fact is, that opposition never materialized. Another couple dozen reactor sites are in the queue for renewal. Most communities near the 60 or so current sites support the high paying jobs, clean air and property tax contributions to local schools and city services.

Favorable Factors

A number of major factors have swung around in favor of nuclear power since the last wave of reactors were ordered in the late 1970s.

  • Low Interest Rates: The sharp climb of interest rates in the late 1970s, to above 15%, combined with licensing delays, caused more reactor cancellations than any other factor. Rates are now near historical lows at 4-6%, enhancing the economics of nuclear units.
  • High Capacity Factors: Last year the U.S. reactor fleet of 103 units achieved a record 91% capacity factor (up from 60% in 1980) and generated 780 billion kWh, also a record, and a fifth of U.S. electricity. Smarter management, operating experience and much shorter fuel outages account for the gains. The fleet has consolidated in the last five years so that a dozen companies now operate nearly 75% of U.S. reactors.
  • Stable Fuel Prices: Compared to the wild gyrations in natural gas prices since 2000, uranium fuel prices have been stable and low, below 0.5 cents/kWh net. Public commissioners and ratepayers like that, and the fuel comes from stable allies Canada and Australia, not volatile governments in the Middle East or elsewhere.
  • Strong Local Support: According to the Nuclear Energy Institute (NEI), one or two dozen reactors can be built at current sites (15,000-30,000 MWe). No “greenfield” plants are needed, and the next reactors won’t be built on Long Island or in San Francisco. In fact, according to Ken Nemeth, Executive Director of the Southern States Energy Board, public policy-makers in several states, particularly in the Southeast, would openly favor construction of new nuclear plants for the local benefits and the stability they bring to regional electricity prices and supply, a welcome contrast to the California electricity crisis in 2000.
  • Advanced Plant Design and Experience: Instead of varying designs, the NRC is now certifying a few reactor designs, and most importantly 3-D/4-D computer-aided design and modeling is much advanced over what was available 25-30 years ago when the last reactors were ordered. Thousands more hours of experience worldwide since 1980 also strengthen the design basis of new reactors. U.S. firms are active in those projects.
  • Emissions Benefits: While U.S. cities have made progress on lead, NOx and SOx, further gains will be reversed unless new reactors are built. Without new construction, electricity from nuclear power will decline from 20% today to below 14% by 2020. Most of the gap will be filled by fossil sources. EIA says that even with sharp growth in renewables, say from 3% to 6% by 2020, wind, solar and biomass will barely offset the forecast decline in hydropower; no new dams are being built either. In addition, nuclear units are uniquely burning up 10,000 tons per year of uranium formerly used in military warheads.
  • “The Hydrogen Economy”: Lastly, U.S. engineering firms also have an eye on modular gas-cooled reactors. If successfully developed and built, these higher-temperature “Generation IV” units could produce large volumes of hydrogen thermo-chemically (using a sulfuric acid – iodide cycle). The energy bill will likely carry provisions for DOE to build a first such reactor. Geoff Ballard, founder of fuel cell maker Ballard Power and chairman of General Hydrogen, stated at the World Nuclear Association meeting in September that “High temperature nuclear units will form the core of hydrogen production for ‘hydricity’ in this century. The other sources don’t begin to deliver the volume we will need to meet growing global demand.” Another wave of light water reactors need to be built now to get to the hydrogen production reactors after 2020.

So Where Are the Orders?

Thirty reactors are now under construction worldwide (>26,000 MW), according to the World Nuclear Association, but none in the U.S. The U.S. energy sector is still absorbing 200,000 MWe of gas-fired plants built in the merchant power boom since 1998. However, erratic and rising gas prices — combined with massive equity devaluations and bankruptcies in merchant energy — have cooled investor and utility interest in new build of anything.

In the Business Case for Nuclear Power completed in July 2002 by Scully Capital for the U.S. Department of Energy (available at, the study’s researchers discovered three “showstopper” risks via interviews with industry executives and investors, any one of which would kill prospects of a utility ordering a new plant:

1) Spent Fuel Disposal: Utility executives believe that opening the Yucca Mountain disposal site in Nevada not only is essential for the current fleet — as courts have already ruled — but Congress backing the licensing and operation of the site makes a clear statement to the country about political commitment to nuclear power. In July 2002, both houses of Congress voted with better than 60% in favor to proceed with the licensing phase, and Bush Administration then approved moving ahead led by Energy Secretary Abraham.

2) Accident Indemnification: Congress will likely extend again the “Price-Anderson” indemnification in the case of nuclear accident. The indemnification only covers third party off-site claims, not losses suffered by utility shareholders, and nuclear operators pay their own portion of the insurance. The Three-Mile Island mishap in 1979 illustrates the point: the containment building worked, no off-site damage occurred, and the business loss of a reactor was borne by utility owners, not taxpayers.

3) Commissioning: The top risk cited by industry, investors and experts was the “Shoreham risk”, the prospect of pouring billions into construction of a unit, only to have it stopped at the last minute on a commissioning technicality or court order. DOE is working with industry and the NRC under the new “Nuclear Power 2010” initiative in 2004 to prove out specific steps of a new “combined Construction and Operating License (COL)” to address this showstopper. Financial backing will also be needed, but the nuclear track record in the U.S. is pretty good: out of 110 reactors built for commercial power, only Shoreham (1989) was not licensed, a default exposure of less than 1%.

Notably, accidents, terrorist attacks and safety were not seen as deal-killers. In fact, last year, the Center for Strategic and International Studies (CSIS) conducted an energy terrorism exercise dubbed “Silent Vector.” The exercise examined the vulnerability of refineries, large LNG/LPG storage facilities, pipelines, petroleum terminals, nuclear power plants, chemical plants and dams. At the conclusion of the exercise, CSIS president John Hamre noted, “Nuclear power plants have become of great concern to everybody. But they are probably our best defended targets.” (Power Engineering, Jan. 2003)

The Last Hurdles

Beyond the three showstoppers, the elevated capital cost of the first few units and the time required to bring a unit on-line are the remaining barriers to a domestic nuclear renaissance. Utilities are interested in ordering the third or fifth unit; federal credit is needed to deal with elevated costs and risks, including the drag on utility earnings during construction and the commissioning risk mentioned above, to get the first few reactors built.

Unfortunately, opponents of nuclear power deliberately muddled the cost figures in Senate debate on the energy bill. The loan guarantees and power purchase provisions proposed in the original energy bill (S.14) could in no way approach the $16 billion figure put forward by the congressional analysts (CRS, CBO), and claimed by Senators Wyden and Sununu as too costly. Projects with a 50% default rate presumed by the Congressional Budget Office (CBO) and nuclear opponents simply would not be put forward by either industry or the federal agency. Based on “caution” and outdated references, CBO rated the default outlook for such projects on par with default rates found in Argentina!

Furthermore, experience by U.S. firms overseas, low interest rates, advances in computer-aided engineering, and industry analysis shows that new reactors could be built for $1800 to $1400 per kW depending on the model, size and financing costs involved, not the $2300 purported by CBO. Fritz Gautschi, past president of Alstom, argued in Power Engineering (March 2003) that nuclear power could be competitive at busbar with capital costs near $1430 per kW if natural gas prices are $3.30/MMBtu. But, with substantially higher demand, plus chronic gas transportation constraints, gas prices in the U.S. now have moved to a $4 to $6 range with higher spikes. Hence, the first few reactors with elevated capital costs in a range of $1600-$1750/kW could be near competitive with some federal credit assistance, particularly in regions where long-term contracts are more the norm.

Federal credit would also help offset the “earnings dilution” utilities could suffer by laying out large amounts of equity investment with no return on it for several years during construction and commissioning. This explains why gas-fired units comprise 95% of new capacity ordered since the onset of competitive electricity rules by FERC in 1998: gas turbines are cheap and can be brought on-line in 12-24 months. But, because fuel comprises over 60% of the electric price from gas-fired units (vs. just 10% with nuclear generation), ratepayers may then suffer rising or volatile prices, and the national energy portfolio becomes unbalanced over time.

Many government agencies, such as the Department of Agriculture and the Department of Transportation, offer financial assistance under the Federal Credit Reform Act (1990) for rural utility projects, transportation infrastructure, and water resource development. Advocates of renewables understand the importance of federal support for first units to help bring higher capital costs down to competitive levels. Federal credit agreements are not “bailouts,” nor are they outright subsidies from the Treasury as ladled out for solar, wind and ethanol. Such agreements (versus unaccountable grants or tax credits), combined with private funding, engineering and operating progress since reactors were last built, dramatically reduce the likelihood of default. Hence, a cautious 10%-20% default rate on $1 billion in federal loan assistance would trigger $100-$200 million in possible budget exposure, not $16 billion! And the first reactors would be built in stages, not all at once.

A bare majority of senators saw through the distorted numbers, defeating a proposed amendment to eliminate the nuclear provisions in a close 48-50 vote on June 10, ably led by Senator Pete Domenici. That vote is a matter of Senate record, not to be cast aside going into the energy debate this fall.

Fact is the other energy sources are already subsidized, some of them heavily. According to analysts, domestic oil exploration receives multi-layered depletion allowances and other tax breaks, totaling over $2 billion a year. The government has invested billions in solar research since the 1970s to help bring the cost of solar equipment down. Because the systems are so small, however, solar still costs more than $10,000/kW (compared to $600/kW for gas-fired turbines). Our nation’s hydropower dams (>80,000 MW) were built by the federal government; and most are still operated by the federal Power Marketing Administrations. Wind power received for several years and still garners a substantial direct subsidy: a 1.8-cent/kWh production tax credit. In this same Senate energy bill (S.14), Democrat farm senators, notably Harkin and Daschle, are making sure ethanol is scheduled for a massive 50 cent per gallon direct subsidy, with a target of 5 billion gallons a year in production before 2010. More than 80% of the nation’s ethanol will be grown in just a handful of Midwestern states. New coal plants are slated in the House version of the energy bill for a 10% investment tax credit, and benefit from a ten-year $2 billion federal “Clean Coal” program already underway.

Taken in perspective, financial assistance provisions contemplated for the energy bill now before Congress amount to a small public investment, especially given the huge emissions benefits and reliable power at stable prices it offers. Nuclear power deserves to be in the energy bill with federal support to preserve its vital position as an anchor of high quality performance in our electricity landscape.
