TRIGA International, the only supplier of TRIGA reactor fuel in the world, recently completed a major renovation project at its fuel fabrication facility in Romans, France. The Department of Energy, which provided both technical and financial support for the project, said the upgrades ensure the continued operation of 36 TRIGA reactors around the world, including 18 in the United States.

Unit 1 at the United Arab Emirates’ Barakah nuclear power plant has entered commercial operation and is now providing “constant, reliable, and sustainable electricity around the clock,” the Emirates Nuclear Energy Corporation (ENEC) announced this morning. ENEC added that, as a result of the event, the company now leads the largest decarbonization effort of any industry in the UAE.

Scientists at the DIII-D National Fusion Facility have published research on a compact fusion reactor design they say could be used to develop a pilot-scale fusion power plant. According to General Atomics (GA), which operates DIII-D as a national user facility for the Department of Energy’s Office of Science, the Compact Advanced Tokamak (CAT) concept uses a self-sustaining configuration that can hold energy more efficiently than in typical pulsed configurations, allowing the plant to be built at a reduced scale and cost.

The Akouta mine in Niger stopped production on March 31 after 43 years of service and 75,000 metric tons of uranium extracted. Akouta, the largest underground uranium mine in the world, was operated by Cominak, a subsidiary of Orano. The shutdown was decided by Cominak’s board of directors on October 23, 2019, in response to the depletion of the mine’s deposit.

March 11 will mark the 10-­year anniversary of the Fukushima Daiichi event, when a 45-­foot tsunami, caused by the 9.0-­magnitude Great Tohoku Earthquake, significantly damaged the reactors at Japan’s Fukushima Daiichi nuclear power plant. In response to this event, the U.S. Nuclear Regulatory Commission took actions to evaluate and mitigate beyond-­design-­basis events, including a new requirement for the staging of so-­called Flex equipment, as well as changes to containment venting and improvements to emergency preparedness. The U.S. Department of Energy also addressed beyond-­design-­basis events in its documented safety analyses.

Building the nation’s first advanced reactor is the goal of a partnership formed between X-energy, Energy Northwest, and the Grant County (Washington) Public Utility District (PUD).

The TRi Energy Partnership will support the development and demonstration of X-energy’s Xe-100 high-temperature gas reactor, which was selected by the Department of Energy for a cost-shared commercial demonstration by 2027 through the DOE’s Advanced Reactor Demonstration Program (ARDP). The new partnership was announced on April 1, when Clay Sell, X-energy’s chief executive officer; Brad Sawatzke, Energy Northwest’s CEO; and Kevin Nordt, the Grant County PUD’s CEO, met in Richland, Wash., to sign a memorandum of understanding.

The North Carolina State University (NCSU) Libraries Department and the Department of Nuclear Engineering are collaborating to build a small modular reactor technical library at NCSU. The library resources will be available to the NCSU research community and to TerraPower/GE Hitachi and X-energy, both of which have signed teaming agreements with NCSU researchers to support planned advanced reactor demonstrations within the next seven years.

Making the new library collection possible: a generous donation from NCSU alumnus Stephen Rea, who together with his wife, Phyllis, formed the Stephen and Phyllis Rea Endowment for Mechanical Engineering Collections in 2015.

“We wanted to seed the endowment and grow it through donations to pursue research and development of green advanced power generation technologies,” Rea explained. “Supporting the advancement of SMR technology development fits our mission statement perfectly.”

Ontario Power Generation’s Centre for Canadian Nuclear Sustainability (CCNS) will collaborate with nuclear technology firm Moltex Energy on a project aimed at recycling used fuel from CANDU reactors, the electricity generator announced March 30.

The CCNS will provide C$1 million (about $800,000) in funding to assist Moltex in demonstrating the technical viability of its process to recycle used CANDU fuel. That process, known as WAste to Stable Salt (WATSS), has the potential to reduce storage needs for used fuel, according to Moltex.

The final nail in the coffin of Ohio’s nuclear subsidies occurred on March 31 when Gov. Mike DeWine signed H.B. 128, a bill passed unanimously by the state’s Senate last Thursday.

Approved 86-7 by the Ohio House on March 10, H.B. 128 strips the nuclear subsidy provisions from H.B. 6, the controversial and, since last July, scandal-scarred piece of legislation signed into law in 2019 to aid Ohio’s economically challenged nuclear facilities, Davis-Besse and Perry.

H.B. 128 also removes the earlier bill’s “decoupling” provision, which would have been of substantial financial benefit to FirstEnergy Corporation, the former parent company of Energy Harbor, owner and operator of Davis-Besse and Perry. The new bill retains H.B. 6’s subsidies for utility-scale solar projects, however, and for two coal plants (one in Ohio, one in Indiana).

H.B. 128 was sponsored by Reps. James Hoops (R., 81st Dist.) and Dick Stein (R., 57th Dist.).

A group of Illinois lawmakers joined Joe Duffy, executive director of the labor coalition Climate Jobs Illinois (CJI), at a virtual news conference on March 29 to unveil a union-focused, clean energy legislative proposal that includes help for the state’s struggling nuclear power plants.

Within the European Union, recognizing nuclear energy as green, sustainable, and worthy of investment depends on nuclear being added to the EU taxonomy of “sustainable investments that have been found to ‘do no significant harm’ to human health and to the environment.” The EU will issue a final taxonomy this year, and a decision to include nuclear power—which was excluded from a draft released in late 2020—could raise prospects for public and private nuclear investments both inside and outside the EU.

The decision rests with the European Commission (EC), which will take into consideration expert opinions, including those in a scientific report of the EC’s Joint Research Centre (JRC) that was requested last summer. The JRC's 387-page report, Technical assessment of nuclear energy with respect to the ‘do no significant harm’ criteria of Regulation (EU) 2020/852 (‘Taxonomy Regulation’), was leaked to the media and made available online on March 26. The report supports adding nuclear to the taxonomy.

The Nuclear Regulatory Commission will discuss the 2020 safety performance of Duke Energy’s Catawba, McGuire, and Oconee nuclear power plants during a virtual meeting to be held on April 1.

The meeting will begin at 5 p.m., eastern time, with a presentation by the NRC staff responsible for plant inspections. Following the discussion with Duke Energy, questions will be answered by the NRC, including by the resident inspectors.

The public and media can access the meeting via Teams. For those without access to Teams, the telephone conference number is 301-576-2978, passcode 71391471#.

The annual assessment letters for the Catawba plant, the McGuire plant, and the Oconee plant, which include upcoming inspection plans for the plants, are available on the NRC website.

Current performance information for Catawba-1, Catawba-2, McGuire-1, McGuire-2, Oconee-1, Oconee-2, and Oconee-3 is available and updated quarterly.

Barrasso

Sen. John Barrasso (R., Wyo.), the ranking member of the Senate’s Energy and Natural Resources Committee, earlier this month introduced legislation, the Combating Global Poverty Through Energy Development Act (S. 758), which aims at removing barriers put up by international financial institutions that limit support for both fossil fuel and nuclear energy projects.

“Developing countries desperately need affordable and reliable energy,” said Barrasso. “Instead of using all available energy options, the World Bank would rather score political points by boycotting critical coal, oil and gas projects. The solution to ending energy poverty does not lie in limiting options. Our bill will encourage the World Bank to eliminate barriers to traditional energy resources, or risk losing American taxpayer funding.”

The bill is cosponsored by Sens. Cynthia Lummis (R., Wyo.), Cindy Hyde-Smith (R., Miss.), Ted Cruz (R., Texas), John Hoeven (R., N.D.), Bill Hagerty (R., Tenn.), John Cornyn (R., Texas), and Jim Inhofe (R., Okla.).

Nuclear power plants not only provide the nation’s largest source of carbon-­free electricity, they also can operate 24 hours a day, 365 days a year to augment intermittent renewables such as wind and solar. Further, studies show that nuclear energy is among the safest forms of energy production, especially when considering factors such as industrial accidents and disease associated with fossil fuel emissions. All said, nuclear has the potential to play a key role in the world’s energy future. Before nuclear can realize that potential, however, researchers and industry must overcome one big challenge: cost.

A team at Idaho National Laboratory is collaborating with experts around the nation to tackle a major piece of the infrastructure equation: earthquake resilience. INL’s Facility Risk Group is taking a multipronged approach to reduce the amount of concrete, rebar, and other infrastructure needed to improve the seismic safety of advanced reactors while also substantially reducing capital costs. The effort is part of a collaboration between INL, industry, the Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-­E), and the State University of New York–Buffalo (SUNY Buffalo).

The Gateway for Accelerated Innovation in Nuclear (GAIN) announced that three nuclear technology companies—Radiant, Oklo, and Lightbridge—will receive GAIN nuclear energy vouchers to accelerate the innovation and application of advanced nuclear technologies. The second set of Fiscal Year 2021 awards was announced March 25.

The Senate Energy and Natural Resources Committee yesterday held a hearing to examine the latest developments in the U.S. nuclear energy sector, with a focus on ways to maintain and expand the use of nuclear in the United States and abroad.

Testifying before the committee were Jeffrey Lyash, president and chief executive officer of the Tennessee Valley Authority (TVA); Chris Levesque, president and CEO of TerraPower, Scott Melbye, president of Uranium Producers of America (UPA); Amy Roma, founding member of the Atlantic Council’s Nuclear Energy and National Security Coalition and a partner with the law firm Hogan Lovells; and J. Clay Sell, CEO of X-energy.

A recent U.S. Energy Information Administration report, Short-Term Energy Outlook, notes that in 2020, nuclear power plants generated more electricity in the United States than coal-fired plants for the first time ever. Last year also marked the first time that coal generation was not the first or second largest U.S. electricity producer in more than 70 years.

Two factors led to the decrease in coal-fired generation, according to the EIA: one is the drop in the number of operating coal-fired plants, and the other is the lower utilization of those remaining coal-fired plants as the nation moves toward cleaner energy production. Coal, however, is not to be abandoned yet, according to the EIA.

The next couple of years will see changes in energy production, according to the EIA report. The EIA believes that "increases in natural gas prices will make coal more competitive in the electric power sector. This expected increase in coal's utilization more than offsets the upcoming retirement of 2.8 GW of coal capacity in 2021 and another 8.5 GW in 2022," based on information reported to the EIA by coal-fired plant owners and developers.

After funding one year of microreactor engineering design work by three teams, the Department of Defense (DOD) announced on March 22 that it has exercised contract options for two of those teams—led by BWXT Advanced Technologies and X-energy—to proceed with development of a final design for a transportable microreactor. Following a final design review in early 2022 and the completion of environmental analysis, one of the two companies may be selected to build a prototype reactor during a 24-­month construction and demonstration phase.

“We are thrilled with the progress our industrial partners have made on their designs,” said Jeff Waksman, Project Pele program manager. “We are confident that by early 2022 we will have two engineering designs matured to a sufficient state that we will be able to determine suitability for possible construction and testing.”

The Canadian government has awarded C$50.5 million (about $40.2 million) to Moltex Energy Canada to support small modular reactor research and technology development in New Brunswick. The investment, announced March 18, was provided by the government’s Strategic Innovation Fund and its Regional Economic Growth Through Innovation program, part of the Atlantic Canada Opportunities Agency (ACOA).

In a press release on the funding, Moltex said it plans to build the world’s first 300-MW Stable Salt Reactor–Wasteburner (SSR–W) and WAste to Stable Salt (WATSS) facility at the Point Lepreau Generating Station site in Saint John, New Brunswick, and provide electricity to the grid by the early 2030s. According to the company, its WATSS process, which recycles existing used nuclear fuel, has the potential to reduce storage needs for that fuel.

Unit II-2 at the Leningrad nuclear power plant entered commercial operation on March 22, bringing the total number of operating power reactors in the Russian fleet to 38, state-owned nuclear power corporation Rosatom has announced.

The 1,066-MWe unit is one of two Russian-designed Generation III+ VVER-1200 pressurized water reactors now in service at the plant, the other, Unit II-1, having begun commercial operation in October 2018. There are also two VVER-1200 units up and running at Russia’s Novovoronezh facility, and two additional VVER-1200s are scheduled for Leningrad later this decade. Further, VVER-1200 projects are afoot at the Belarusian plant in Belarus (two units), El Dabaa in Egypt (four units), Hanhikivi in Finland (one unit), and Paks in Hungary (two units).

Leningrad II-2 replaces Leningrad I-2, a 925-MWe RBMK-1000 light water–cooled graphite-moderated reactor that permanently ceased operation in November 2020 after 45 years of service.
