Unit 1 at South Korea’s Shin-Hanul nuclear power plant entered commercial operation last week, Korea Hydro & Nuclear Power has announced. The 1,340-MWe APR-1400—designed by KHNP and parent firm Korea Electric Power Company—achieved initial criticality on May 22 of this year and was connected to the grid on June 9.

X-energy, a developer of small modular reactors and nuclear fuel technology, has entered into a definitive business combination agreement with Ares Acquisition Corporation (AAC). As a result of the agreement, X-energy will become a publicly traded company, a status that is expected to boost its growth strategy, investment opportunities, and financial flexibility. In addition, X-energy will receive differentiated sponsorship by Ares Management Corporation, which describes itself as a “leading global alternative investment manager.” The transaction is expected to be finalized in the second quarter of 2023.

A study published recently in the American Physical Society journal Physical Review C reveals new findings about the strong nuclear force, the mysterious fundamental force that holds together the protons and neutrons of the atomic nucleus. Experiments conducted at Argonne National Laboratory have shown how the round, heavy nuclei of the nickel-64 isotope (containing 28 protons and 36 neutrons, making it the heaviest stable Ni isotope) changed into one of two shapes—either like a doorknob or a football—depending on the amount of energy exerted on it. A summary of the research on the Phys.org website compares the nuclei shape change to popcorn kernels changing shape when heated in a microwave.

Cold hydro testing of Unit 4 at the Vogtle plant’s nuclear expansion site has been completed, Georgia Power announced on December 7.

The Department of Energy yesterday awarded the American Nuclear Society and Energy Communities Alliance Inc. (ECA) a combined $800,000 to connect with communities across the country and establish education and outreach opportunities in nuclear energy. (A Washington, D.C.–based nonprofit, ECA “brings together local government officials to share information, establish policy positions, and promote community interests to address an increasingly complex set of constituent, environmental, regulatory, and economic development needs,” according to its website.)

Nuclear Newswire is back with the final #ThrowbackThursday post honoring the 80th anniversary of Chicago Pile-1 with offerings from past issues of Nuclear News. On November 17, we took a look at the lead-up to the first controlled nuclear chain reaction and on December 1, the events of December 2, 1942, the day a self-sustaining nuclear fission reaction was created and controlled inside a pile of graphite and uranium assembled on a squash court at the University of Chicago’s Stagg Field.

The Department of Energy’s Office of Nuclear Energy announced December 7 that its new HALEU Consortium is open for membership. And not just from U.S. enrichers, fuel fabricators, and others working in the front-end fuel cycle, but from “any U.S. entity, association, and government organization involved in the nuclear fuel cycle,” and—at the DOE’s discretion—“organizations whose facilities are in ally or partner nations.” The HALEU Consortium will essentially serve as an information clearinghouse to meet DOE-NE’s ongoing needs for firm supply and demand data as it supports the development of a commercial domestic high-assay low-enriched uranium (HALEU) infrastructure to fuel advanced reactors. The consortium is open for business almost one full year after the DOE first requested public input on its structure.

The Nuclear Regulatory Commission has docketed Vistra Corporation’s license renewal application for the Comanche Peak reactors.

Operated by Vistra subsidiary Luminant and located in Glen Rose, Texas, the Comanche Peak plant is home to two pressurized water reactors. The original 40-year licenses for Units 1 and 2 expire in February 2030 and February 2033, respectively.

For years the U.S. nuclear industry has done an outstanding job keeping plant availability high while simultaneously continuing to improve safety and economics. With capacity factors averaging more than 90 percent, you would think that no one would shut down an operational nuclear power plant. But that is what we have seen in a number of cases. Fortunately, this now seems to be changing. As I write this column, Diablo Canyon’s new life extension application has just been submitted to the Nuclear Regulatory Commission for review, and the Department of Energy’s program to support continued operation of nuclear power plants is providing hope that current plants will continue to have the opportunity to demonstrate their operational excellence.

How did we get here? When I ask this question—both of myself and the industry as a whole—I envision this as two sides of the same coin. Through the efforts of many we have improved our financial and economic viability, but challenges remain because the full value proposition of nuclear energy has not been realized.

The British government has announced an investment of £679 million (about $828 million) in the proposed Sizewell C nuclear plant in Suffolk, England, confirming chancellor of the exchequer Jeremy Hunt’s remarks on the project in his November 17 Autumn Statement.

The Ontario government has announced the start of site preparation at the Darlington nuclear power plant for Canada’s first grid-scale small modular reactor: GE Hitachi Nuclear Energy’s (GEH) BWRX-300.

The Nuclear Regulatory Commission’s Office of Regulatory Research recently awarded 20 new research and development grants in the University Nuclear Leadership Program (UNLP). The grants, totaling $9,998,188, are derived from the $16 million that Congress appropriated for the program for fiscal year 2022. The 20 selected proposals were among the 89 that were submitted to the NRC and peer-reviewed by the commission staff and experts from academia.

A Westinghouse-Bechtel team, France’s EDF, and Korea Hydro & Nuclear Power have all submitted their initial bids for securing the contract to build a fifth reactor at the Czech Republic’s Dukovany plant, Czech utility ČEZ has announced.

ANS will host a members-only event on December 7 from 1:00 to 2:00 p.m. EST with Jigar Shah, director of the Department of Energy’s Loan Programs Office (LPO). Craig Piercy, ANS executive director and chief executive officer, will lead the interview.

Register now: Hear about the ambitious goals of the Biden administration to decarbonize the power sector by 2035, which were highlighted in Shah’s article in the November issue of Nuclear News. Shah will also discuss how nuclear can be an important part of the decarbonized energy mix in the United States and how he believes the LPO can support the administration’s target.

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.

Centrus Energy confirmed on December 1 that its wholly owned subsidiary American Centrifuge Operating signed a contract with the Department of Energy, which was first announced on November 10, to complete and operate a demo-scale high-assay low-enriched uranium (HALEU) gaseous centrifuge cascade.

NorthStar Medical Radioisotopes has completed construction and all equipment installation at its new facility in Beloit, Wis., to produce the medical radioisotope molybdenum-99 without the use of high-enriched uranium, the Department of Energy’s National Nuclear Security Administration announced last week.

The ITER Organization is working on a new baseline schedule for the magnetic confinement fusion experiment launched in 1985 and now under construction in southern France. First plasma was scheduled for December 2025 and deuterium-tritium operations for 2035 under a schedule approved in November 2016 that will soon be shelved. In addition to impacts from COVID-19 delays and uncertainty resulting from Russia’s war in Ukraine, ITER leaders must now factor in repair time for “component challenges.”

Westinghouse Electric Company has announced the signing of a long-term technology license agreement with Swedish engineering services firm Studsvik to develop a metals recycling and treatment facility at Westinghouse’s Springfields site.

Located near Preston, Lancashire, in northwestern England, Springfields is the United Kingdom’s only site for nuclear fuel manufacturing, supplying all its advanced gas-cooled reactor fuel. According to Westinghouse, Springfields fuel is responsible for about 32 percent of Britain’s low-carbon electricity generation. In addition, the site exports other nuclear fuel products to customers around the globe.
