Clarifying the Record on AB 2647: A Technical Response to Opposition Claims

Contrary to some characterizations, California Assembly Bill 2647 (AB 2647) does not mandate nuclear deployment, waive safety review, or eliminate environmental protections. It establishes a narrow, administrable pathway for California to evaluate advanced reactors that have already met federal licensing standards. The bill preserves existing oversight while removing a statutory barrier to consideration.

Some responses to AB 2647 misunderstand the recent modernization of the Nuclear Regulatory Commission. Reforms, developed through bipartisan federal legislation, do not weaken safety requirements. Instead, the reforms adopt risk-informed, technology-inclusive approaches that better align regulatory review with actual reactor designs and risk profiles. There is a diversity of advanced reactor technologies, and treating them as a single category imposes unnecessary limitations. Modern designs incorporate advances in materials, modeling, and safety systems, and must meet or exceed existing safety standards under NRC oversight.

Failing to incorporate nuclear energy in modern grid and energy system planning is not without cost. Maintaining a categorical prohibition on nuclear energy limits California’s ability to consider firm, zero-carbon resources that could complement renewable generation and support grid reliability amid rising electricity demand.

Concerns about waste disposal, while unresolved at the federal level, are not addressed by California’s moratorium and remain subject to existing federal regulatory requirements. Attacking AB 2647 on the basis of waste disposal achieves nothing. On-site storage of nuclear waste remains a viable and safe option until the federal government creates and licenses a permanent geologic depository.

Oppositional claims often rely on generalized risk framing rather than project-specific or regulatory analysis. AB 2647 instead provides a legally durable and analytically grounded framework for evaluating advanced nuclear technologies on their merits within California’s broader clean energy strategy.
