Description (excerpt):

Achieving net-zero emissions in the United States by mid-century requires the rapid buildout of low-carbon energy infrastructure. One challenge to this rapid buildout is the environmental reviews required by the National Environmental Policy Act (NEPA), which are part of federal approval processes for new energy projects. This process has increasingly caused significant delays and added costs, and the Fiscal Responsibility Act (FRA) of 2023 was passed by Congress in part to address these issues through amendments to NEPA that impose timelines on environmental reviews.

For nuclear power, a low-carbon energy source that has a role in many US net-zero scenarios, environmental reviews are conducted by the US Nuclear Regulatory Commission (NRC) as part of its reactor licensing process. Because this process has at times been lengthy and costly, Congress passed the 2024 ADVANCE Act in part to require the NRC to implement its responsibilities under NEPA more efficiently. During the 2000s and 2010s, most of the environmental impact statements (EISs) these reviews produced would not have complied with NEPA’s new FRA timeline (two years or fewer) and page limit (150, or in extraordinary cases 300). More recent NRC environmental reviews for test reactor deployments have been somewhat quicker and had shorter review documents, perhaps a recognition by the agency that the efficiency of this process needed improvement.

This report, part of a series of publications on nuclear licensing reform at the Center on Global Energy Policy at Columbia University SIPA, focuses on how the NRC can fulfill the new legal mandates on time and page limits for environmental reviews and in general improve the efficiency of these reviews. The report demonstrates that earlier (1970s–80s) environmental reviews for nuclear power reactors licensed under the 10 CFR 50 licensing pathway took less time and generated shorter review documents than those conducted under 10 CFR 52 during the 2000s and 2010s. The latter reviews—all of which were for large light water reactor projects—also utilized substantial NRC resources, thereby incurring significant costs to the applicants. None of these reviews found that the reactor projects were expected to create what the NRC calls “large adverse” environmental impacts, which could destabilize environmental resources.
