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.

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.

By all accounts the most productive nuclear power plant in British history, Somerset’s Hinkley Point B station closed for good on August 1, with the shutdown of its B1 unit, a 485-MWe advanced gas-cooled reactor. (The plant’s B2 unit, a 480-MWe AGR, was shuttered early last month.)

The station employed around 500 staff and 250 contractors and contributed approximately £40 million (about $48.7 million) per year to the Somerset economy, according to EDF Energy, owner and operator of the United Kingdom’s power reactor fleet.

At the June ANS Annual Meeting in Anaheim, Calif., our Executive Director/CEO Craig Piercy used an interesting acronym: he said, “This meeting is so exciting we are going to give nuclear professionals FOMO with respect to ANS meetings going forward.” The term “fear of missing out” was common a few years ago, but I had not heard it recently. So when Craig used it, it really caught my attention. Craig was, of course, correct that the Annual Meeting was great: technically interesting, productive, and great fun, as well. It provided a wonderful opportunity to learn, network, and advance both academic and business goals. However, in thinking about this phrase I realized that in a lot of ways, getting people to realize how important nuclear science and technology is for making the world better is a lot like trying to get people to understand that they are truly missing out.

Energy Secretary Jennifer Granholm visited Idaho National Laboratory on August 3 to meet with INL staff, including director John Wagner, as she toured key research facilities on INL’s 890-square-mile site and the lab’s campus in Idaho Falls.

The Nuclear Regulatory Commission has authorized Vogtle plant operator Southern Nuclear to load fuel and begin operation at Unit 3—the first reactor to reach this point in the agency’s combined license process. (Prior to 1989, reactors were licensed under a two-step process, requiring both a construction permit and an operating license.)

Crowell

Caputo

The Senate last evening confirmed by voice vote Annie Caputo and Bradley R. Crowell to seats on the Nuclear Regulatory Commission, returning the agency to its full, five-member complement. Caputo’s term expires in June 2026, Crowell’s in June 2027.

Nominated by President Biden in May to serve on the commission, Caputo and Crowell appeared before the Senate Environment and Public Works (EPW) Committee on June 8 to field questions. On July 27, the EPW Committee unanimously approved both and sent their nominations to the Senate floor.

SHINE Technologies, the Janesville, Wis.–based producer of medical radioisotopes, announced that it has submitted a drug master file (DMF) with the U.S. Food and Drug Administration for non-carrier-added (n.c.a.) lutetium-177 chloride, a radiopharmaceutical used for the treatment of cancer.

The Nuclear Regulatory Commission announced on August 2 that it had issued a confirmatory order to the National Institute of Standards and Technology (NIST) for violating NRC requirements during a February 2021 fuel failure at the 20-MWt NIST Center for Neutron Research (NCNR) research reactor in Gaithersburg, Md. NIST committed to improving its training for fuel handing procedures and related management activities, safety culture program, reactor facility operations staff and management, corrective action program and operational procedures, and emergency response resources and procedures, among other things.

Last Energy, a Washington, D.C.–based small modular reactor startup, has signed a letter of intent with Poland’s Legnica Special Economic Zone (LSSE) and DB Energy for a power plant featuring 10 small modular reactors with 200 MWe of capacity to fuel the region’s industrial activities. (Established in 1997, the LSSE covers 18 subzones located in the central part of southwestern Poland’s Dolnośląskie Province and is home to more than 75 companies providing some 16,000 jobs.)

Lesko

Rep. Debbie Lesko (R., Ariz.) last week introduced legislation to require the Nuclear Regulatory Commission to assess its nuclear power plant oversight and inspection practices and to implement improvements.

According to a press release from Lesko’s office, the bill—the Advancing Nuclear Regulatory Oversight Act—directs the NRC to report to Congress any policies that it revised or suspended during the COVID-19 pandemic and how these changes impacted the agency’s ability to conduct its oversight duties. In addition, the measure requires the NRC to submit a report identifying improvements to its oversight and inspection programs to maximize efficiency without compromising safety.

Just this last April, President Biden officially commissioned the USS Delaware, a new Virginia-­class nuclear attack submarine, the 18th built in that class and the eighth and final Block III Virginia-­class submarine. (The Delaware was administratively commissioned in April 2020, but the COVID-­19 pandemic caused delay of the ceremony for two years.)

The Nuclear Regulatory Commission issued its final environmental impact statement (EIS) for the proposed license renewal of Westinghouse Electric’s Columbia Fuel Fabrication Facility (CFFF) in Hopkins, S.C, on July 29, recommending renewal for a 40-year term.

The Nuclear Regulatory Commission has directed its staff to issue a final rule certifying NuScale Power’s small modular reactor design for use in the United States, the agency announced last Friday.

Certification of the Portland, Ore.–based SMR developer’s design will become effective 30 days after publication of the rule in the Federal Register. The design will be incorporated as Appendix G to 10 CFR Part 52, Licenses, Certifications, and Approvals for Nuclear Power Plants.

In recent years, the rate of building new nuclear power plants has slowed internationally except in some rapidly developing countries. In Western countries that have considerable experience with nuclear power, completion of new projects on time and on budget has become more difficult. Shipyard-fabricated plants may offer a new direction for meeting international needs and responding to requirements for better cost control and safety. In this article we offer an overview of the floating nuclear power plant concept, including experience with it to date and its key engineering and strategic features, along with related uncertainties and needed conditions for future projects to be successful.

In a 243–187 vote, the House of Representatives yesterday passed the CHIPS and Science Act of 2022, a $280 billion economic competitiveness package aimed at bolstering U.S. semiconductor manufacturing, as well as scientific research and development, including nuclear energy R&D.

Nuclear energy offers a pairing of high capacity factors and low carbon emissions unrivaled by other power sources, and advanced reactors and small modular reactors (SMRs) hold promise to deliver that power with even more efficiency and versatility. Researchers in the public and private sectors, backed by government funding through programs like the Department of Energy’s Advanced Reactor Demonstration Program and Advanced Research Projects Agency–Energy (ARPA-E), are bringing that promise closer to fulfillment by engineering solutions to open questions about advanced reactor materials and fuel cycles.

The DIII-D National Fusion Facility now boasts a unique automated system that allows for a quick reversal of the direction of its magnetic field, expanding the range of possible fusion experiments while reducing downtime. General Atomics, which operates the DIII-D for the Department of Energy’s Office of Science, announced the new Toroidal Field Reversing Switch (TFRS) on July 26.

The Nuclear Regulatory Commission recently approved, in a 2–1 vote, a recommendation from its staff that could potentially lead to the siting of advanced reactors in more densely populated areas than is permitted for traditional light water units.

NRC chairman Christopher Hanson and David Wright voted in favor of the recommendation, with Jeffery Baran casting the lone “nay” vote. (There are currently two open seats on the five-member commission.)
