In a letter to NuScale Power, the Nuclear Regulatory Commission responded to the company’s draft standard design approval application (SDAA) for its small modular reactor design by identifying “several challenging and/or significant issues that could be focus areas for the SDAA acceptance and/or safety review.” The letter described the findings of the NRC’s preapplication readiness assessment and recommended NuScale’s “continued engagement” on a number of topics of concern before finalizing the SDAA.

Two reports agree: Diverse advanced reactor fuel cycles can succeed

November 23, 2022, 6:39AMNuclear News

Advanced reactors and small modular reactors with strikingly different coolants and sizes offer an array of different benefits, but when it comes to fuel cycle issues, including spent fuel and waste, they have a lot in common with conventional light water reactors. Two reports released within the last week—a National Academies of Sciences, Engineering, and Medicine (NASEM) consensus committee report two years in the making and a Department of Energy study released by Argonne National Laboratory—address the timely topic of advanced reactor fuel cycle issues. While the NASEM committee ventured to define research and infrastructure needs to support the entire nuclear power fuel cycle, inclusive of new technologies, for decades to come, the DOE report compares the front- and back-end fuel cycle metrics of three reactor designs (from NuScale Power, TerraPower, and X-energy) that have been selected for DOE cost-share–funded demonstrations within this decade. Together, these reports provide assurance that the fuel cycle needs of a fleet of new reactors can be met and point to near-term research and planning needs.

Participating in the forum were (from left) John Hopkins (NuScale Power), Renaud Crassous (EDF), Daniel Poneman (Centrus Energy), Adriana Cristina Serquis (CNEA), and Boris Schucht (Urenco).

The nuclear industry leaders assembled in Washington, D.C., last week to discuss small modular reactor supply chains agreed that lost generation capacity from the expected retirement of hundreds or thousands of coal power plants over the next decade—a cliff, in one panelist’s words—represents an opportunity that developers of SMRs and advanced reactors are competing to meet.

“I think in total 80 projects are ongoing,” said Boris Schucht, panel moderator and chief executive officer of Urenco Group, as he opened the forum. “Of course not all of them will win, and we will discuss today what is needed so that they can be successful.”

GAO finds nuclear demo best practices could set new standard for clean energy projects

October 3, 2022, 12:00PMNuclear News

The Department of Energy’s management of its commercial-scale reactor demonstration projects has “generally been consistent with requirements to address risk,” according to a Government Accountability Office (GAO) report published recently. The GAO found that the DOE has met existing project management requirements, and that the two offices managing the awards—the Office of Nuclear Energy (NE) and the Office of Clean Energy Demonstrations (OCED)—plan to introduce additional project management tools, such as external independent reviews. The GAO recommended that the DOE adopt those plans as institutional best practices for other large energy projects, and the DOE concurred.

Nesbit, Huff among others quoted in NYT article on nuclear power

July 12, 2022, 7:00AMANS Nuclear Cafe


Steven Nesbit, ANS’s immediate past president, is among the nuclear industry leaders quoted in a recent New York Times article about the renewed interest in nuclear power in the United States. The article explains that the challenges of meeting clean energy goals and surging electricity demands are prompting many government officials to take “a fresh look at nuclear power—both extending the life of existing reactors and building new ones.” The article also presents the views of some nuclear critics.

Much of the article focuses on the fate of California’s Diablo Canyon nuclear power plant, which is currently scheduled for shutdown in 2025. Several of the state’s lawmakers who previously supported the shutdown, including Gov. Gavin Newsom and Sen. Diane Feinstein, are now considering supporting the extended life of the plant. A joint study by Stanford University and the Massachusetts Institute of Technology has concluded that a 10-year extension of Diablo Canyon could substantially reduce carbon emissions, lessen reliance on natural gas, cut electricity costs, and minimize the risk of brownouts.

Legislation to spur clean energy innovation debuts on Capitol Hill

July 30, 2021, 7:00AMNuclear News

Approximately 40 percent of cumulative carbon dioxide emission reductions needed to meet sustainability targets rely on technologies not yet commercially deployed on a mass-market scale, according to last year’s Special Report on Clean Energy Innovation from the International Energy Agency.



Intent on lowering that percentage, both the Senate and House earlier this week introduced bipartisan legislation to rapidly scale up and diversify emerging energy technologies. On July 27, Sens. Mike Crapo (R., Idaho), ranking member of the Senate Finance Committee, and committee member Sheldon Whitehouse (D., R.I.) introduced the Energy Sector Innovation Credit (ESIC) Act, or S. 2475. The credit, according to Crapo’s office, is a technology-inclusive, flexible investment tax credit (ITC) or production tax credit (PTC) designed to promote innovation across a range of clean energy technologies, including generation, energy storage, carbon capture, and hydrogen production.

When Utah Associated Municipal Power Systems (UAMPS) in 2015 announced its plan to develop the Carbon Free Power Project (CFPP) using NuScale Power’s modular light water reactor design, it envisioned the construction of a dozen 50-MWe modules for a plant that could produce a total of 600 MWe. The CFPP’s target output later rose to 720 MWe, when UAMPS opted to scale up to 60-MWe modules. In late June, the plans changed once again, as UAMPS participants chose to build 77-MWe modules but downsize the plant from 12 units to six, which would yield 462 MWe—about 64 percent of the 720 MWe that could have been generated from 12 of the 60-MWe modules.
