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.)

The Department of Energy today issued a Record of Decision (ROD) for the Final Versatile Test Reactor Environmental Impact Statement (final VTR EIS; DOE/EIS-0542). The VTR will be a sodium-cooled, fast-neutron-spectrum test reactor that will enhance and accelerate research, development, and demonstration of innovative nuclear energy technologies critical to tackling the climate crisis, according to the DOE.

The VTR ROD and final VTR EIS are available for viewing or download here.

The Belgian government has signed a nonbinding letter of intent with Electrabel, a subsidiary of the French utility Engie, to keep nuclear a part of Belgium’s energy mix for an additional 10 years.

Electrabel operates Belgium’s two nuclear power plants, the four-unit Doel and three-unit Tihange.

Romania’s Nuclearelectrica, the state-owned operator of the two-unit Cernavoda nuclear power plant, has awarded Candu Energy a contract to conduct design and engineering services for the facility’s Unit 1 refurbishment project, according to an announcement last week from SNC-Lavalin, Candu Energy’s parent company.

The June 2017 special report on the ANS Nuclear Grand Challenges (available online at ans.org/challenges/) identified low-dose radiation as a crucial focus area for ANS. Specifically, the challenge is to “Establish the scientific basis for modern low-dose radiation regulation.” This is particularly difficult given the long review cycles associated with International Commission on Radiological Protection (ICRP) and National Council on Radiation Protection and Measurements (NCRP) recommendations. Additionally, while the Environmental Protection Agency is tasked with issuing guidance on radiation exposure standards in the United States, responsibility for implementing and enforcing radiation protection regulations is distributed throughout the federal government. Finally, while it is accepted that tissue reactions (previously called deterministic or nonstochastic effects) exhibit a dose threshold, there is still substantial scientific debate over the shape of the dose response at low doses for stochastic effects, such as cancer. Despite these hurdles, substantial progress has been made over the past five years on the low-dose radiation grand challenge.

The Department of Energy earlier this year approved part one of a loan application from Holtec International for small modular reactor construction and invited the firm to apply for a loan to help build four of its SMR-160 units and grow its manufacturing capacity to produce the first wave of SMRs.

While the construction of two additional reactors at Slovakia’s Mochovce nuclear plant (Units 3 and 4) may get most of the attention, it isn’t the only major project underway there. In October of last year, plant owner Slovenské Elektrárne commenced the first phase of an effort to revitalize two of the four 125-meter-tall, Iterson-type cooling towers that serve the facility’s two operating reactors—both of which began generating electricity in the late 1990s. Towers #11 and #21 had been refurbished in 2011 and 2012, respectively. The other two, however, towers #12 and #22, had never undergone refurbishment.
