Nuclear energy touted at West Virginia Chamber forum, but key cost, oversight and waste management questions linger

The Herald Dispatch, By Mike Tony 4 Sept 23

West Virginia political and business leaders made clear during last week’s state Chamber of Commerce annual summit they see a significant role for nuclear power in the state’s energy future.

“It’s a promise for our state,” Sen. Shelley Moore Capito, R-W.Va., said of nuclear energy during a summit speech at The Greenbrier resort in White Sulphur Springs Wednesday.

But recent federal reports have observed key cost, waste management and federal oversight questions linger over unconventional — or “advanced” — nuclear technologies that supporters say would be safer and cheaper than existing nuclear reactors.

……………………………………….. Emil Avram, vice president of business development at Virginia-based Dominion Energy,  estimated the nuclear facility Dominion is exploring would require an investment of $3 billion to $5 billion per 300- to 400-megawatt facility — and that the company is planning to build up to 18 of those units over the next 25 years.

“So we also have to find sustainable, I’ll call it balance-sheet solutions for our company as we build out this capital-intensive infrastructure,” Avram said.

……………………………………Small modular reactor technology is not yet market-ready. The Department of Energy has approved cost-share awards to develop small modular reactors that can be operational by the end of the decade.

A Congressional Research Service overview of advanced nuclear reactors published in February noted research on small modular reactors suggesting their small size will keep them from achieving economies of scale.

The overview noted a 2018 study by researchers from Carnegie Mellon and Harvard universities and the University of California, San Diego predicting the cost per unit of power of a small modular reactor would very likely be higher than that of a large reactor, even if the smaller reactors may be cheaper to build.

The unit cost of producing electricity from nuclear energy was slightly more than coal and over double that of solar, geothermal, onshore wind or natural gas in the federal Energy Information Administration’s annually published energy outlook for 2022.

In its overview, the Congressional Research Service, a nonpartisan policy analysis agency within the Library of Congress, quoted a 2023 conclusion from the National Academies of Sciences, Engineering, and Medicine that there’s a “learning curve for both small modular reactor construction costs and deployment [that] needs to be understood……………………………………………………

The West Virginia Legislature lifted restrictions on nuclear power plant construction early in the 2022 regular legislative session.

The Senate on July 27 included the Capito and Carper-led nuclear measure, the Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy (ADVANCE) Act, in the National Defense Authorization Act that passed through the chamber. The National Defense Authorization Act would approve fiscal year 2024 appropriations and establish policies for Department of Defense programs…………………………………………..

A recent federal government watchdog report found the agency charged with protecting public safety and health regarding nuclear energy has important work to do to prepare for an expected influx of advanced nuclear reactor applications.

The Nuclear Regulatory Commission has staffing and licensing review issues that could hinder the agency’s oversight and developers’ ability to deploy advanced nuclear reactors, the Government Accountability Office found in its report released in July.

The office found commission officials and most stakeholders it interviewed indicated the commission faces challenges in hiring and retaining staff needed to review advanced reactors.

Existing commission guidance does not clearly advise agency staff on how to establish and manage licensing review schedules for incomplete applications, the Government Accountability Office found.

Without such guidance, the commission’s reviews of advanced reactor applications may not be clear and predictable, the office warned.

Capito and Rep. Cathy McMorris Rodgers, R-Wash., the top Republican on the House Energy and Commerce Committee, had asked the office last year to assess the commission’s preparedness to review and approve advanced nuclear reactor applications.

the Congressional Research Service noted some advanced reactor technologies have chemical properties that pose safety concerns, including reactivity, toxicity, or corrosiveness of the primary coolant in the case of sodium, lead and molten salts, respectively.

It’s unclear whether future advanced nuclear reactor technologies would improve on past handling of reprocessing wastes, the Congressional Research Service report observed. The service cited a National Academies of Sciences, Engineering, and Medicine report published this year finding that amounts and types of waste that will be generated by advanced reactors are difficult to estimate “at this early stage” of development.  https://www.herald-dispatch.com/news/nuclear-energy-touted-at-wv-chamber-forum-but-key-cost-oversight-and-waste-management-questions/article_7941cf2a-19dc-57e7-a44d-30a7672728da.html
