The US Supreme Court’s recent Loper Bright decision overturned its 1984 Chevron decision, which, over the last 40 years, had become a fundamental doctrine in administrative law. That doctrine, known as the “Chevron deference,” instructed reviewing courts to defer to agency interpretations of ambiguous statutory provisions if a permissible construction of the statute. While many agencies relied on Chevron deference to defend challenges to their rulemakings and other regulatory actions, the NRC has rarely needed to do so.

The NRC’s Acting Executive Director for Operations recently issued the results from the NRC staff’s annual Reactor Oversight Process (ROP) self-assessment for calendar year 2023. Out of the 17 metrics it evaluated, the NRC staff found that two did not meet or exceed expected performance, resulting in “yellow” findings. This is an overall improvement from the 2022 self-assessment, which had two “yellow” and two “red” findings due, in part, to continuing challenges from the COVID-19 pandemic. Overall, the staff concluded that the “ROP remained effective in achieving its goals of being objective, risk-informed, understandable, and predictable, as well as in supporting the agency’s strategic goals.”

The House Subcommittee on Energy, Climate, and Grid Security held a hearing on April 10, 2024 to examine federal responsibility for the permanent disposal of spent nuclear fuel (SNF), along with opportunities for mitigating disposal challenges—such as through reprocessing and recycling fuel—to advance nuclear energy for the nation.

With the change of a single number, Congress has provided continued support for the nuclear power industry by renewing the Price-Anderson Act. Congress amended Section 170 of the Atomic Energy Act of 1954 (commonly known as the Price-Anderson Act or PAA) by changing its expiration date to December 31, 2065 from December 31, 2025. Congress also increased fourfold the liability coverage for DOE contractors for a nuclear incident occurring outside the United States to $2 billion from $500 million. Finally, Congress revised the definition of “nuclear incident” to remove requirements for the underlying nuclear material.

The US Department of Energy (DOE) has published a final rule increasing civil monetary penalties (CMPs) for unintentional violations of 10 CFR Part 810 (Part 810). The rule, which took effect on January 9, 2024, increases the maximum CMP from $120,816 to $124,732 per violation per day. The increased penalty aligns with DOE’s mandate to annually adjust CMPs for inflation.

In a final rule published in the Federal Register on October 19, 2023, the NRC amended its regulations at 10 CFR 140.11 to increase the amount of third-party liability coverage required under the Price-Anderson Act, Section 170 of the Atomic Energy Act (42 USC 2210) (Price-Anderson) for large reactor licensees (i.e., reactors with a rated capacity of ≥100 MWe) from $450 million to $500 million per incident.

Over the course of 2023, the US Nuclear Regulatory Commission (NRC) has started to develop a regulatory framework for fusion energy systems. Significantly, and as we previously reported, NRC decided to modify the existing process for licensing the use of byproduct materials contained in 10 CFR Part 30 to regulate nuclear fusion. NRC has now issued preliminary proposed rule language for the licensing and oversight of a broad array of fusion systems currently under development.

As fiscal year 2024 approaches, a partial government shutdown looms on the horizon once more. This would be the first partial government shutdown since the 36-day shutdown that began in late December 2018 and ended on January 25, 2019. While the NRC was unaffected by that shutdown because its FY 2019 budget had been enacted, at this time Congress has not passed any of the annual appropriation bills for FY 2024, including that for the NRC.

In a Federal Register Notice published September 5, 2023, the NRC amended its regulations to be effective October 5, 2023, to adjust for inflation the maximum total and annual deferred premium amounts for the “secondary layer” of offsite liability coverage, as required by the Price-Anderson Act, as amended, Section 170 of the Atomic Energy Act (42 USC 2210) (Price-Anderson).

The NRC has now followed up on that guidance with revisions to RG 5.83, “Cybersecurity Event Notifications (Revision 1),” to address new cybersecurity concerns, provide clarification, and align with new guidance in RG 5.71. This guidance is critical for the nuclear industry given the rapid pace at which cybersecurity threats and deterrent strategies evolve. All nuclear power reactor owners must review NRC’s latest guidance and confirm that their cybersecurity programs are in compliance.
