The Nuclear Regulatory Commission turned the tables a bit on its inspector general’s office this week, releasing its response to a March 25 OIG event inquiry that criticized an NRC inspection at California’s Diablo Canyon nuclear power plant, performed after a July 2020 auxiliary feedwater (AFW) system failure at Unit 2.

The response highlights a number of what the agency terms “factual errors” and takes issue with several portions of the OIG report.

Finnish energy company Fennovoima has terminated, effective immediately, its engineering, procurement, and construction (EPC) contract with RAOS Project Oy, a subsidiary of Russia’s Rosatom, for the delivery of a 1,200-MWe VVER-1200 pressurized water reactor at the Hanhikivi site in Finland’s Pyhäjoki municipality.

China’s State Council recently approved the construction of four Westinghouse AP1000 reactors—two at China’s Sanmen plant in Zhejiang Province and two at the Haiyang plant in Shandong Province.

The plants currently house two AP1000 units each. Sanmen’s reactors are rated at 1,157 MWe and Haiyang’s at 1,170 MWe. Sanmen-1 and -2 began commercial operation in 2018. Haiyang-1 started commercial operation in 2018, and Haiyang-2 in 2019.

NuScale Power has signed a collaboration agreement with the U.S. Reactor Forging Consortium (RFC) to leverage the nation’s forging supply chain to prepare for the deployment of NuScale’s small modular reactor technology and to support, maintain, and expand U.S. manufacturing jobs.

California Gov. Gavin Newsom told the Los Angeles Times editorial board last week that his administration would look into using the federal government’s Civil Nuclear Credit Program to keep Pacific Gas and Electric Company’s Diablo Canyon nuclear plant in operation beyond its scheduled 2025 closure date.

“The requirement is by May 19 to submit an application, or you miss the opportunity to draw down any federal funds if you want to extend the life of that plant,” Newsom told the board, according to an April 29 LA Times piece. “We would be remiss not to put that on the table as an option.”

The Waste Management Symposia, the premier forum on the management and disposition of radioactive waste, took place in person this year March 6–10 in Phoenix, Ariz., after being held virtually in 2021 due to the COVID-­19 pandemic. With more than 2,100 paid participants, the prevailing feeling at the conference was one of getting back to normal after two long years without face-­to-­face contact.

McMorris Rodgers

Rep. Cathy McMorris Rodgers (R., Wash.), ranking member of the House Energy and Commerce Committee, and Fred Upton (R., Mich.), ranking member of the Subcommittee on Energy, sent a letter to energy secretary Jennifer Granholm on April 27 urging that more be done to secure America’s nuclear energy sector.

Excerpt: “Russia’s invasion of Ukraine exposes the risks of weakening American energy security,” McMorris Rodgers and Upton write. “These risks extend beyond our oil and gas assets to include supply vulnerabilities in our civilian nuclear sector. This sector is essential for national and energy security and for strengthening the geostrategic relationships necessary to compete with Russia, China, and other adversaries.

Small modular reactor developer NuScale Power has signed a memorandum of understanding with three South Korean companies—Doosan Enerbility Company, GS Energy Corporation, and Samsung C&T Corporation—to explore the deployment of NuScale’s VOYGR power plants in Asia.

The accident at Unit 2 of the Three Mile Island nuclear power plant on March 28, 1979, was an extremely complex event. It was produced by numerous preexisting plant conditions, many systemic issues in the industry and the Nuclear Regulatory Commission, unanticipated operator actions, previously unrecognized thermal-­hydraulic phenomena in the reactor coolant system (RCS), and the unprecedented challenge of managing a severely degraded core.

The director general of the International Atomic Energy Agency, Rafael Mariano Grossi, led a mission to Ukraine’s Chernobyl nuclear plant this week to address ongoing radiological safety concerns at the shuttered site following five weeks (February 24–March 31) of Russian military occupation.

Bechtel has signed memorandums of understanding with a dozen Polish companies for the potential development of two nuclear power plants as Poland seeks to lessen its dependence on domestic coal and Russian imports for its energy supply.

The MOUs were signed on April 25 during a ceremony at the U.S. ambassador’s residence in Warsaw. Offering services ranging from earthwork and infrastructure construction to concrete, tunneling, electrical installations, and heavy cranes, the 12 Polish firms are BAKS, Budimex, Doraco, Energoprojekt-Katowice, Hitachi Energy Poland, ILF, KB Pomorze, Mostostal Warzsawa, Polimex Mostostal, Protea Group, Vistal Gdynia, and Zarmen.

The Nuclear Regulatory Commission is seeking input from the public regarding the first set of results from its multiyear Level 3 Probabilistic Risk Assessment Project to analyze risk at a reference two-reactor nuclear power plant site.

The project, which began in 2012, updates risk insights obtained from work done more than 30 years ago, according to the NRC. The project examines a reference site with two large pressurized water reactors and associated spent fuel. It builds on Level 1 (possible reactor core damage scenarios) and Level 2 (possible radioactive material release scenarios) analyses to estimate potential health effects and economic impacts.

“If the electorate through their elected leaders demand stable or lower electricity costs, and new coal is off the table, only nuclear power offers hope,” writes nuclear engineer Joseph Somsel in reference to the Philippines presidential election, scheduled for May 9. Somsel, who expressed his views on the Nuclear Engineering International website this month, notes that the leading ticket in the election consists of presidential candidate Ferdinand Marcos Jr., son of the former dictator, and vice presidential candidate Sara Duterte, daughter of the current president. The ticket has been running ads supporting nuclear power while condemning high electricity prices.

The Department of Energy has issued a funding opportunity announcement (FOA) aimed at developing partnerships between the Office of Nuclear Energy (NE) and various communities. Partners will work with local energy communities, educational entities, and other constituencies to accomplish the shared mission of utilizing nuclear energy to advance energy, environmental, and economic initiatives, according to the DOE.

“The war in Ukraine has intensified interest across Europe in building new nuclear energy plants or extending the lives of old ones to liberate the continent from its heavy reliance on Russian oil and natural gas,” Washington Post reporters Steven Mufson and Claire Parker write in their recent article, before describing what they view as the potential dangers of nuclear energy. They also quote the American Nuclear Society in regard to the Chernobyl nuclear site in Ukraine.

In an editorial published recently in the Chicago Tribune, the newspaper’s editorial board states, “As for the U.S., power generation from splitting atoms has declined in recent years, and more reactors are being retired than built. If you’re in Illinois, however, you’re all-in on nuclear energy—for better or worse. Gov. J.B. Pritzker has made sure of that.”

The Department of Energy has awarded a grant worth $2.5 million to Constellation and its project partners to investigate the potential benefits of direct air capture (DAC) technology at its Byron nuclear power plant in Illinois. DAC would remove carbon dioxide directly from the atmosphere, a possible next-generation technology to help combat climate change.

The Department of Energy has announced the steps that would-be applicants must take to access funds from the $6 billion Civil Nuclear Credit (CNC) Program. Guidance published April 19 invites owners or operators of those plants most at risk of near-term closure to apply during the program’s first award cycle. With shutdown planned next month, Entergy’s Palisades plant would top that list (read on for more on Michigan’s efforts to keep the plant operating), but any reactor with publicly announced plans to close by September 30, 2026, that meets other program criteria could be certified for credits. Successful applicants won’t have to wait long for good news: the DOE plans to announce award decisions as soon as 30 days after the May 19 deadline for submitting certification applications together with sealed bids for credits.

The Tennessee Valley Authority and Ontario Power Generation announced on April 19 that they have formed a partnership to develop and deploy advanced nuclear technology as part of their broader efforts to work toward clean energy. According to the agreement, the companies will coordinate their activities in designing, licensing, constructing, and operating small modular reactors.

Kairos Power announced today that it has assembled an advanced nuclear development advisory consortium with four North American nuclear operators—Bruce Power, Constellation, Southern Company, and the Tennessee Valley Authority—dubbed Kairos Power Operations, Manufacturing and Development Alliance (Kairos Power-OMADA).
