Small Modular Nuclear Reactors ~ Bad Deal or Terrible Deal

Small Modular Nuclear Reactors studied by Union of Concerned Scientists

From the Letter by Rees Shearer, Virginia Mercury, February 16, 2023

In announcing his 2022 Virginia Energy Plan, Gov. Youngkin said, "A growing Virginia must have reliable, affordable and clean energy for Virginia's families and businesses." The Governor's plan to promote and subsidize Small Modular nuclear Reactors (SMnRs) in Southwest Virginia fails all three of the Governor's own criteria:

>>> SMnRs can't be reliable when they cannot reliably be built and brought on line in a predictable and timely fashion.

>>> SMnRs can't be affordable because nuclear power is close to the costliest of all forms of electric power generation.

>>> SMnRs can't be clean since they produce extremely toxic high and low-level nuclear waste, which has no safe storage or disposal solution.

Appalachia has long served as a sacrifice zone for rapacious energy ambitions of other regions. Southwest Virginians have had reason to hope that would change as opportunities for low-cost solar development emerged in recent years. Instead, politicians like Youngkin are making too-good-to-be-true promises about SMnRs, sidelining opportunities to promote solar, which can produce power in a matter of weeks, not decades.

Imposing SMnRs on Southwest Virginia is disturbing. My father worked for the Atomic Energy Commission in the 1950s. The promise the nuclear industry and the government touted then – "electricity, too cheap to meter" – never has been realized. TVA and other utilities abandoned nuclear plants under construction, leaving costly monuments to that folly and sticking electricity customers with the bill.

COSTS: It's not at all clear that SMnR technology will succeed, or when. Levelized cost charts of electric power generation rate nuclear as among the very most expensive means to generate electric power at utility scale. If nuclear waste management, insurance, and decommissioning costs are counted, actual costs are far higher. (Some of these costs are already socialized for nuclear power – e.g. insurance in the Price-Anderson Act.)

The first commercial SMnR is not expected to be completed until 2029, but already its developers have raised the target price of its power by 53%. This is not a surprise; nuclear power construction history documents an extremely strong correlation between new designs and cost increases and project delays. Indeed, the Lazard research shows that nuclear is the ONLY grid-wide generation source to increase in price, 2009-2021. The increase was 36%!

NUCLEAR WASTE, TRANSPORT, AND REPROCESSING: Nuclear waste and reprocessing are also serious concerns. Make no mistake, unreprocessed nuclear waste, for all practicable purposes, is FOREVER. The fact that we have become accustomed to risk does not, by any means, reduce risk. Nor will SMnRs generate less waste than their larger forebears. Indeed, a recent Stanford University study concluded that "small modular reactors may produce a disproportionately larger amount of nuclear waste than bigger nuclear plants."

Safeguarding this waste is already costing taxpayers and utility customers tens of billions of dollars. With the failure of the U.S. to designate a central storage facility, nuclear power plants are forced to continue to store the waste in pools on site.

Yet nuclear waste recycling, known as reprocessing, is no panacea. In November, the Governor spoke in Bristol in support of recycling nuclear waste from SMnRs: "I think the big steps out of the box are the technical capability to deploy in the next 10 years and on top of that to press forward to recycling opportunities for fuel." He may have had in mind BWX Technologies of Lynchburg, which is beginning reprocessing of uranium at its Nuclear Fuel Services (NFS) plant just south of the Virginia border in Erwin, Tennessee, for nuclear weapons.

It took over a decade, but in 1984, Congress finally killed the last proposal to reprocess nuclear waste into nuclear fuel. The reprocessing would have taken place at the Clinch River Breeder Reactor, also south of the Virginia border, near Oak Ridge, TN. The concern then was the potential for accidental highly toxic "spills" of nuclear wastes or purposeful diversion of plutonium into the international weapons market. I recall this clearly because I spoke at a public hearing in Abingdon about the transportation of nuclear waste that would be bound for the Clinch River plant.

Transportation of SMnR nuclear wastes along Virginia mountain roads or railroads across the border to Erwin presents further risk of accident and contamination. Longstanding concerns about transportation and security of nuclear wastes have never been adequately addressed.

In addition, Princeton University physicist, Frank N. von Hippel reported in the Bulletin of Atomic Scientists that the Nuclear Regulatory Commission, charged with protecting U.S. citizens from reactor disasters such as Three Mile Island, Chernobyl, or Fukushima, has moved toward offering greater flexibility for a nuclear industry plagued by cost overruns and calls for safety improvements, rather than hewing to its primary responsibility for maintaining safety of nuclear generating facilities and the American people. The Bulletin also reports that, because of longstanding financial troubles experienced by the commercial nuclear power industry, state legislatures are increasingly being asked and are feeling compelled to subsidize nuclear power. Gov. Youngkin's state energy plan would take Virginia down that road, a road that could be very long.

URANIUM MINING in VIRGINIA? Because of toxic pollution risks, mining uranium in Virginia is currently prohibited under a moratorium enacted by the General Assembly. Coles Hill in Pittsylvania County contains the largest deposit of uranium in the U.S. Just a month ago, Consolidated Uranium, a Canadian company, announced its purchase of Virginia Energy Resources, which owns Coles Hill. It sounds like those executives think that another run at overturning the mining moratorium might be successful. That this purchase announcement comes so shortly after Youngkin's announcement of SMnRs in his Virginia Energy Plan feels like more than coincidence.

Uranium mining in a wet, eastern location would present a far higher opportunity for contamination than mining that has for years had problems affecting water and public health in the West. We Appalachians know the social and environmental costs of an extractive economy. We should not support any enterprise that forces that kind of exploitation upon our neighbors, especially mining with known, pervasive health, safety and environmental risks.

CORPORATE CRONYISM and POLITICAL BOONDOGGERY: BWX Technologies of Lynchburg (formerly Babcock and Wilcox) is the nuclear contractor we can anticipate would be charged with Gov. Youngkin's wish to reprocess nuclear waste into fuel. BWX has been on the ropes for years, since nuclear became so unpopular with utilities in the wake of the Three Mile Island accident. It has managed to stay afloat with military contracts and wants to develop the reactors it builds for subs and aircraft carriers for commercial power production. The SMnRs are its ticket, and Gov. Youngkin is playing both their salesman and the state's purchasing agent. Some General Assembly members are angling to help their localities and favored industries cash in.

“Advanced” Isn’t Always Better ~ Assessing the Safety, Security, and Environmental Impacts of Non-Light-Water Nuclear Reactors, Edwin Lyman, March 18, 2021

If nuclear power is to play an expanded role in helping address climate change, newly built reactors must be demonstrably safer and more secure than current generation reactors. Unfortunately, most “advanced” nuclear reactors are anything but.

The Union of Concerned Scientists undertook a comprehensive analysis of the most prominent and well-funded non-light-water reactor (NLWR) designs. We asked:

§- What are the benefits and risks of NLWRs and their fuel cycles ?
§- Do the likely overall benefits of NLWRs outweigh the risks and justify the substantial public and private investments needed to commercialize them?
§- Can NLWRs be safely and securely commercialized in time to contribute significantly to averting the climate crisis?

Based on the available evidence, we found that the NLWR designs we analyzed are not likely to be significantly safer than today's nuclear plants. In fact, certain alternative reactor designs pose even more safety, proliferation, and environmental risks than the current fleet.
