The American Nuclear Society has published the first voluntary consensus standard for nuclear reactor design that formally incorporates risk-informed, performance-based (RIPB) decision-making in July 2022. ANSI/ANS-30.3-2022, Light Water Reactor Risk-Informed, Performance-Based Design, tells reactor designers how they can incorporate RIPB principles and methods to ensure safety in new commercial light water reactor designs, and it includes a spectrum of options using both deterministic and risk-based approaches. As the first such standard, ANSI/ANS-30.3-2022 represents progress toward the adoption of RIPB principles for nuclear regulation and licensing—a shift the Nuclear Regulatory Commission was directed to make in the Nuclear Energy Innovation and Modernization Act, which became law five years ago.

The Nuclear Regulatory Commission has announced its intention to award 22 education grants worth a total of $8.2 million to 16 academic institutions in 15 states. The grants, which are part of the NRC’s University Nuclear Leadership Program (UNLP), are meant to support nuclear engineering and science programs. Two of the recipient schools are classified as minority-serving institutions.

The Nuclear Regulatory Commission has opened registration for its 36th annual Regulatory Information Conference, to be held March 12–14 online and in person in North Bethesda, Md. The NRC is expecting several thousand attendees from the United States and around the world for the three-day event.

Registration is required to attend. The full conference program and registration information is available on the NRC’s RIC website and on NRC social media platforms under the tag #NRCRIC2024.

The Nuclear Regulatory Commission has scheduled two meetings in February to discuss the environmental evaluation and review process for the license renewal application of the two-unit Diablo Canyon nuclear power plant in Avila Beach, Calif.

Baran

The White House has given up on the renomination of former Nuclear Regulatory Commission member Jeff Baran because of bipartisan opposition in the Senate, according to multiple media reports. After a handful of Democrats joined Senate Republicans to block the nomination last year, President Biden has decided to drop Baran as his pick, HuffPost first reported on Monday.

Baran joined the five-person federal panel in 2014 as an appointee of former president Barack Obama. The NRC oversees atomic energy and radiation safety and has become increasingly politicized in recent years, as different parties push for new processes and procedures for building new reactor types and expanding nuclear infrastructure.

Baran’s term ended in June 2023, and since then the commission has been without a tie-breaker for party-line votes among the four current members. Come June 30, NRC chair Christopher Hanson will complete his term and has yet to be renominated.

The Japan-U.S. Decommissioning Workshop Series continues on February 8–9 when its second forum meets to discuss the handling of low-level radioactive waste (LLW) generated during the decommissioning process and how improved LLW management can reduce risk.

Registration for the online event is required. The registration deadline is 2:00 a.m. (EST) on February 5.

The Nuclear Regulatory Commission and the Federal Energy Regulatory Commission will meet on January 25 to discuss grid reliability, operating reactors, advanced reactor activities, cybersecurity, and other topics.

Joseph Hendrie, Brookhaven National Laboratory physicist, NRC chair, and ANS past president (1984–1985), passed away in his home in Bellport, N.Y., on December 26 at the age of 98.

Hendrie, an American Nuclear Society member since 1956, was a leader in the nuclear community for much of his 45 years in nuclear reactor safety research. He served as the deputy director for technical review of the Atomic Energy Commission’s Directorate of Licensing from 1972 to 1974 and then was appointed chair of the NRC in 1977 (serving a second stint as chair in 1981—the only person to serve two nonconsecutive terms in that role).

Another calendar year has passed. Before heading too far into 2024, let’s look back at what happened in 2023 in the nuclear community. In today's post, compiled from Nuclear News and Nuclear Newswire are what we feel are the top nuclear news stories from January through March 2023.

Stay tuned for the top stories from the rest of the past year.

NuScale announced today a 28 percent reduction in full-time staff, affecting 154 workers, as part of the company’s move to focus resources on “key strategic areas”— including deployment of its small modular reactor.

The Nuclear Regulatory Commission has finalized an inspection finding as “white” related to an inoperable emergency diesel generator at the V. C. Summer nuclear power plant in Jenkinsville, S.C. Under the NRC’s reactor oversight process, a white inspection finding reflects low-to-moderate safety significance.

“Maintaining the operational readiness of all safety-related equipment is crucial for the plant's ability to respond effectively in emergencies,” said Laura Dudes, NRC Region II administrator. “While not indicative of immediate risk, this finding underscores the need for continuous vigilance and improvement in the plant’s corrective action process.”

The Nuclear Regulatory Commission has accepted for review Pacific Gas and Electric’s formal request to extend Diablo Canyon nuclear power plant’s operating licenses for another 20 years.

The Nuclear Regulatory Commission is discontinuing probation on Mississippi’s program for regulating the use of radioactive materials. According to the NRC, the decision is the result of the agency’s review earlier this year that found the state has made significant progress in addressing several areas of unsatisfactory performance.

The Nuclear Regulatory Commission has granted Holtec Decommissioning International’s request to revise the emergency preparedness plan for the Palisades nuclear power plant in Covert, Mich., to reflect the plant’s decommissioning status.

The development of modern nuclear reactor technologies relies heavily on complex software codes and computer simulations to support the design, construction, and testing of physical hardware systems. These tools allow for rigorous testing of theory and thorough verification of design under various use or transient power scenarios.

The Nuclear Regulatory Commission announced that it will hold a hybrid public meeting on December 7 to discuss the license termination process and to accept comments on the remaining cleanup activities under the license termination plan for the Crystal River-3 nuclear power plant in Crystal River, Fla.

Climate change presents a grave threat, demanding increasing reliance on low-carbon energy over the coming decades. Nuclear power today contributes half of U.S. low-carbon generation, and achievement of climate goals requires the continued operation of existing plants. But there are competitors for low-carbon energy, and nuclear’s further role remains uncertain. The National Academies of Sciences, Engineering, and Medicine (NASEM) conducted a study to explore the challenges that must be overcome for widespread new nuclear deployment.¹ This article provides my summary of the study, highlighting and abbreviating some of its principal recommendations. Note that the italicized portions of the article are shortened versions of the recommendations in the report.

Outside my office, there is a display case filled with rock samples from all over the world. It contains a disk of translucent, orange salt from the Waste Isolation Pilot Plant near Carlsbad, N.M.; a core of white-and-bronze gneiss from the site of the future deep geologic repository in Eurajoki, Finland; several angular chunks of fine-grained, gray claystone from the underground research laboratory at Bure, France; and a piece of coarse-grained granite from the underground research tunnel in Daejeon, South Korea.
