Brief:
The U.S. Nuclear Regulatory Commission (NRC) is opening a window for public commentary until December 18 on a newly revamped initiative aimed at expediting its environmental review process for the approval of new nuclear reactors. This information is unveiled in a recent notice published on a Friday in the Federal Register.
The cornerstone of this proposal is the incorporation of the NRC’s draft Generic Environmental Impact Statement (GEIS) for Licensing New Nuclear Reactors. The GEIS serves as a technology-agnostic framework designed to highlight potential environmental impacts that are typically associated with the construction, operation, and eventual decommissioning of various new nuclear reactors. According to the NRC, this generic analysis is essential for a comprehensive environmental evaluation.
By leveraging the conclusions drawn from the NR GEIS before embarking on obligatory project-specific environmental analyses, the NRC anticipates that applicants and the commission could save nearly $2 million for each application. Cumulatively, over the next ten years, the savings could soar to around $40.1 million, provided the NRC processes an estimated 20 new reactor applications during this timeframe.
Insight:
In a strategic move back in April, the NRC voted to formalize an earlier framework pertaining to advanced nuclear reactor applications. NRC officials predicted that this rule could slash application costs by a staggering 20% to 45%, as highlighted by Judi Greenwald, the Executive Director of the Nuclear Innovation Alliance, in an April 24 statement.
"The Commission’s decision to enshrine this framework builds upon best practices in environmental review,” noted Greenwald, emphasizing that it will facilitate a more effective, efficient, and predictable licensing process for advanced reactors.
Moreover, an April 17 memorandum from NRC Secretary Carrie Safford instructed the commission’s staff to widen the rulemaking package and associated guidance. This expansion meant that it would now encompass any new nuclear reactor application, as long as the application aligns with the predefined parameter envelopes utilized in developing the GEIS.
These pivotal amendments are encapsulated within the new proposal, which aims to apply universally to any new fission reactor application that satisfies the conditions outlined in the NR GEIS. However, it’s important to note that this proposed rule does not extend to applications for novel fusion reactors, which fall under a different regulatory structure pertaining to byproduct materials as prescribed by the NRC.
There lies potential for this new rule to be applicable to microreactor applications; nevertheless, further examination is deemed necessary to ascertain its implications for applicants classified as “small entities” under NRC size standards. The commission is currently seeking comments to inform the rulemaking process regarding an initial regulatory flexibility analysis that addresses these concerns.
With the NR GEIS in play, the NRC will be better positioned to identify which environmental impacts are universally applicable to multiple reactor types and which are unique to specific projects. This layered approach necessitates a subsequent project-specific environmental review, particularly for those uncommon or exceptional concerns.
By narrowing the focus on particular project-related issues, the proposed rule seeks to diminish the financial burden associated with conducting environmental assessments, benefiting both applicants and the NRC itself. Apart from rendering cost reductions of up to $2 million per application, the NRC anticipates that this new rule will foster enhanced regulatory predictability, stability, and clarity throughout the licensing journey.
The NRC’s expectation of receiving 20 new reactor applications in the near future mirrors the growing optimism among nuclear advocates regarding an uptick in licensing activity. This sentiment aligns with a significant update from the U.S. Department of Energy’s recent report, "Pathways to Commercial Liftoff: Advanced Nuclear," which lays out an ambitious roadmap for advancing 200 GW of new nuclear capacity in the U.S. by 2050. A separate DOE study released in September suggested that this target could be met solely through the deployment of new reactors situated at sites of existing nuclear and decommissioned coal plants.
