Just over one year ago, on August 8, 2021, researchers achieved a yield of more than 1.3 megajoules (MJ) at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) for the first time, achieving scientific ignition and getting closer to fusion gain.

The scientific results of the historic experiment were published exactly one year later in three peer-reviewed papers: one in Physical Review Letters and two (an experimental paper and a design paper) in Physical Review E. In recognition of the many individuals who worked over decades to enable the ignition milestone, more than 1,000 authors are included on the Physical Review Letters paper.

In the latest episode of a years-long dispute, the D.C. circuit court has denied a petition to reverse the Nuclear Regulatory Commission’s 2014 decision granting a license to Powertech USA for uranium extraction at its Dewey Burdock site, the company’s parent, enCore Energy, announced yesterday.

The ANS Board of Directors recently approved two position statements from the Public Policy Committee: a revision to PS #35, Advanced Reactors, and the completely new PS #84, Safeguards and Security for Advanced Reactors Using HALEU. ANS’s position statements reflect the Society’s perspectives on issues of public interest that involve various aspects of nuclear science and technology and are prepared by key members whose relevant experience or publications inform the documents. Prior to approval for publication, the documents are reviewed by relevant ANS committees and divisions.

All high-enriched uranium has been removed from the Kyoto University Critical Assembly (KUCA), according to an announcement from the U.S. Department of Energy’s National Nuclear Security Administration.

Teollisuuden Voima Oyj (TVO), owner and operator of the Olkiluoto nuclear power plant in Finland, has resumed Olkiluoto-3’s test production phase, following completion of maintenance and repair work at the new reactor’s turbine island, the company announced this week.

TVO had announced in June a delay to the unit’s commercial start of some three months—from September to December—after material that had detached from the steam guide plates was found in the turbine’s steam reheater in May, necessitating repair work and a halt to testing.

The Department of Energy has chosen Los Alamos National Laboratory to lead a $9.25 million collaborative project to model the behavior and properties of structural materials in molten salt through the Scientific Discovery through Advanced Computing (SciDAC) program and announced the news August 9. The team working on the five-year project includes experts from LANL; Carnegie Mellon University; and Idaho, Lawrence Berkeley, and Sandia national laboratories.

While the Mississippi Public Service Commission earlier this year accepted a $300 million offer from Entergy Corporation to settle its portion of a multistate dispute with the utility over Grand Gulf nuclear plant customer rate impacts, the Arkansas Public Service Commission last week turned down its own $142 million offer, terming it “a low-ball amount.”

United Cleanup Oak Ridge (UCOR), the lead environmental cleanup contractor for the Department of Energy’s Oak Ridge Office of Environmental Management (OREM), has been named one of the Knoxville News Sentinel’s “Top Workplaces” in eastern Tennessee for 2022. The award is the result of a confidential, third-party survey of UCOR’s 2,000-member workforce by the Knoxville News Sentinel and the survey company Energage.

Small modular reactor developer X-energy and materials science giant Dow this morning announced the signing of a letter of intent aimed at deploying X-energy’s Xe-100 reactor technology at one of Dow’s U.S. Gulf Coast facilities. The companies expect the SMR plant, which would provide power and process heat to the Dow facility, to be operational by approximately 2030.

Dow is the first manufacturer to declare its intention to develop SMR technology options and intends to take a minority equity stake in X-energy, according to the announcement.

News of the collaboration broke at the American Nuclear Society’s Utility Working Conference and Vendor Technology Expo, being held through August 10 at Marco Island, Fla.

Mexican authorities announced last week that the Mediterranean fruit fly, more commonly known as the medfly, had been successfully eradicated in the state of Colima using a nuclear technique described by the International Atomic Energy Agency (IAEA) as “birth control for pests.” Mexico used the sterile insect technique (SIT) in cooperation with the IAEA and the Food and Agricultural Organization of the United Nations (FAO) to protect fruit and vegetable crops, farmers’ livelihoods, and the country’s economy.

X-energy and Dow announced today a collaboration with intent to deploy an advanced small modular reactor at one of Dow’s U.S. Gulf Coast facilities. The SMR, which would be operable by about 2030, would provide heat and power to the Dow facility.

The announcement was made at the American Nuclear Society's Utility Working Conference and Vendor Technology Expo (UWC 2022), being held through August 10 at Marco Island, Fla.

The Electric Power Research Institute (EPRI) has launched the Nuclear in District Energy Applications (NuIdea) Initiative to support the use of nuclear power in district energy systems. The new program, which is part of the EPRI’s Nuclear Beyond Electricity Initiative, has the goal of promoting microreactors (up to 10 MW) for heating, cooling, and power applications in institutional settings by 2026.

At the recent ANS Annual Meeting, Andrew Klein, past ANS president (2016–2017), professor emeritus of nuclear science and engineering at Oregon State University, and the current editor of ANS’s journal Nuclear Technology, announced his retirement at the end of his term in June 2023. ANS is looking for qualified members who are interested in becoming the next technical editor of the journal. The selected person will be appointed “editor-designate” and will work with Dr. Klein for a period of time before taking over the full editor’s role.

Klein, professor emeritus at Oregon State University and past ANS president, took over the duties of technical editor in 2015, a few years before his term as ANS president. During his tenure as editor, Dr. Klein has raised NT ’s reputation for technical excellence and arranged a schedule of twelve issues annually covering the most important topics in nuclear technology.

The American Nuclear Society (ANS) President Steven Arndt and ANS CEO and Executive Director Craig Piercy issued the following statement on the Inflation Reduction Act of 2022:

New and immersive internship and development opportunities are being offered through a partnership of Westinghouse Electric Company and the Ukrainian nuclear energy utility Energoatom. Beginning this autumn, more than 60 opportunities will be available for Ukrainian nuclear energy professionals and graduate-level students.

ANS’s August 4 online event “The New Space Race is Going Nuclear” featured several expert panelists who discussed the growing importance of nuclear technologies in space commercialization and exploration. Although nuclear energy has long played a role in space missions, participants discussed the latest exciting developments in the space nuclear field and presented their views on how increased application of nuclear technologies could fundamentally transform the ways in which both crewed and uncrewed space missions are carried out.

The Tennessee Valley Authority and GE Hitachi Nuclear Energy (GEH) have signed an agreement to support planning and preliminary licensing for the potential deployment of a BWRX-300 small modular reactor at the Clinch River site near Oak Ridge, Tenn., the utility’s president and chief executive officer, Jeff Lyash, announced last week.

An evolution of GEH’s 1,520-MWe Generation III+ ESBWR design, the BWRX-300 is a 300-MWe water-cooled, natural-circulation SMR with passive safety systems.

Statement from American Nuclear Society President Steven Arndt and Executive Director and CEO Craig Piercy:

All 92 U.S. power reactors operating today need water—in the right place and at the right time. But extreme weather events, including floods, droughts, hurricanes, and heat waves, upend expectations and demand resilience: the ability to anticipate, accommodate, and recover from adverse impacts.

Resilience was built into today’s nuclear power plants decades ago. Weather data and climate forecasts not available then can be factored into risk analysis now to ensure the plants remain resilient in a changing climate.

SNC-Lavalin subsidiary Candu Energy recently announced that it is engaged in pre-project design and engineering work at the Qinshan Phase III nuclear power station in China’s Zhejiang Province with Third Qinshan Nuclear Power Company (TQNPC), the plant’s operator.
