The American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee (RP3C) held another Community of Practice (CoP) on April 26. For this event, the committee welcomed Mory Diané of Oklo. RP3C chair N. Prasad Kadambi led with a brief introduction before Diané shared Oklo's risk-informed, performance-based (RIPB) approach to seismic design categorization and seismic siting characterization.

Diané, a licensing manager with Oklo, is a structural engineer with a background in civil engineering

The Nuclear Regulatory Commission this week announced the window is open for members of the public to request a hearing on the construction permit application for TerraPower’s Natrium nuclear power plant, which is set to be built near Kemmerer, Wyo.

As advocates for the environment, national security, and U.S. prosperity, and as believers that the substantial global expansion of nuclear energy is essential to these interests, let’s take a moment to recognize how far we have come.

In recent years, much has changed. Public opinion polls show increasingly broad support for nuclear energy, which has bipartisan and bicameral support in Congress. The U.S. is on the cusp of achievements that could usher in a new era of nuclear energy and reestablish U.S. global leadership. The prevailing question is no longer whether we need nuclear energy, but rather, how much more nuclear power do we need, how can we enable first movers, and how quickly can we deploy new reactors.

During the 2024 International Conference on Nuclear Security (ICONS) in May, representatives from the U.S. Department of Energy and the National Nuclear Security Administration discussed U.S. nuclear security priorities, noted their achievements and those of U.S. partners, and explained how to tackle the security challenges of today and tomorrow.

The Nuclear Regulatory Commission hosted a public meeting yesterday to gather comments on its web-based ADAMS (WBA) system—a public document search tool introduced in 2010. It’s a tool that novice users find daunting and frequent users find frustrating, whether they’re searching for a single document or for thousands of documents on a single topic.

The Nuclear Regulatory Commission is issuing a final rule and corresponding update to the generic environmental impact statement (GEIS) the agency uses when considering applications to renew the operating licenses of nuclear power reactors. All four current NRC commissioners voted to approve the rule on May 16.

Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

The Nuclear Regulatory Commission is holding a webinar on May 21 to get public input on how the Agencywide Documents Access and Management System—known as ADAMS—is working for the public.

A bill being considered in the U.S. Senate seeks to remove the requirement for the Nuclear Regulatory Commission to hold a public hearing for every nuclear reactor application.

Current law requires public hearings to be held by the NRC toward the end the reactor license application process, in addition to the statutorily required environmental and safety reviews that provide public engagement opportunities for stakeholders and citizens.

Another year, another stellar performance by America’s nuclear plants. We’ve come to expect high capacity factors, and it’s a credit to the men and women of the profession. They’ve made routine something that was unimaginable not so long ago.

The decadal challenge for the nuclear enterprise now is to maintain this high level of operational excellence for the current fleet, while at the same time ushering in a new generation of technologies at scale. It will be a big job—but one that seems more and more likely with each passing day.

It is against this hopeful backdrop that I take the opportunity to update you on our latest steps toward making the American Nuclear Society a class-leading professional society.

The Nuclear Regulatory Commission has published its annual report to Congress for fiscal year 2023 on abnormal occurrences involving medical and industrial uses of radioactive material.

The report, which was announced by the NRC on May 3, is available on the NRC website.

Borehole disposal of spent nuclear fuel (SNF) and high-level waste (HLW) uses off-the-shelf directional drilling technology developed and commercialized by the oil and gas sectors. It is a technology that has been gaining traction in recent years in the nuclear industry. Disposal can be done in one or more boreholes (including an array) drilled into suitable sedimentary, igneous, or metamorphic host rocks. Waste is encapsulated in specialized corrosion-resistant canisters, which are placed end to end in disposal sections of relatively small-diameter boreholes that have been cased and fluid-filled. After emplacement, the vertical access hole is plugged and backfilled as an engineered barrier.

The American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee (RP3C) on March 29 held another presentation in its monthly Community of Practice (CoP) series. The presenter, Patrick White with the Nuclear Innovation Alliance (NIA), talked about the current status of efforts to develop a new regulatory framework for advanced reactors—known as 10 CFR Part 53 or simply Part 53. White serves as the research director of the NIA, where he leads their research as well as analysis-based stakeholder and policymaker engagement and education. White’s March 29 presentation is publicly available on YouTube and at ANS’s publication platform Nuclear Science and Technology Open Research (NSTOR).

RP3C chair N. Prasad Kadambi opened the CoP with brief introductory remarks about the RP3C before he welcomed White as the session’s presenter.

White covered three main topics: the history of the existing regulatory frameworks for new reactors, progress to date on the development of the Part 53 rule for advanced reactors, and the current status and next steps for the Part 53 rulemaking process.

By an order dated April 25, the Nuclear Regulatory Commission has approved the transfer of ownership of Vallecitos Nuclear Center from GE Hitachi Nuclear Energy to NorthStar Group Services for nuclear decontamination, decommissioning, and environmental site restoration.

A review from the Ninth Circuit Court of Appeals this week denied a challenge to the Diablo Canyon nuclear plant’s license renewal application extension granted by the federal government.

In late 2023, the Nuclear Regulatory Commission agreed to formally docket the California plant’s request to extend plant operations beyond the current license expiration dates of 2024 and 2025 for the two respective units.

The Nuclear Regulatory Commission is seeking input on its draft environmental assessment and draft finding of no significant impact for Kairos Power’s application to build the Hermes 2 test reactor facility in Oak Ridge, Tenn.

The Nuclear Regulatory Commission is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.

In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

The Nuclear Regulatory Commission will hold a public meeting on May 8 to discuss the license termination process for the retired nuclear-powered merchant ship, the NS Savannah. During the meeting, NRC staff will discuss the license termination process and receive public comments on the remaining cleanup activities described in the license termination plan for the historic ship, which may see a second life as a floating museum.

Nuclear Regulatory Commission staff will host a public information meeting on Wednesday, April 17, to discuss plans for repowering the shuttered Palisades nuclear plant in Michigan.

TerraPower’s application to build its Natrium nuclear power plant near Kemmerer, Wyo., is available for public viewing on the Nuclear Regulatory Commission website.
