The Nuclear Plant Decommissioning Act of 2025 aims to increase transparency and local involvement in the decommissioning of nuclear power plants. It amends the Atomic Energy Act of 1954 to establish new requirements for licensees regarding post-shutdown decommissioning activities reports (PSDARs) and license transfers. These changes are designed to ensure that state, tribal, and local governments, as well as the public, have a meaningful role in the decommissioning process. Before submitting a proposed PSDAR or license transfer application, licensees must consult with affected states and tribal/local governments located within 50 miles of the facility. The bill mandates that the Nuclear Regulatory Commission (NRC) solicit public comments for at least 90 days in the host state, including written comments and at least two public meetings. This ensures broad community input on decommissioning plans. A key provision allows the host state to submit a statement of support, conditional support, or nonsupport for the proposed PSDAR or license transfer. If the host state offers conditional support, the NRC must incorporate the recommended changes unless they violate applicable law or their costs substantially outweigh their benefits. The NRC's final decision, which must consider public input and financial assurance, is due within one year and is considered a final order. The bill establishes two grant programs to support community advisory boards (CABs) that foster communication between licensees and affected communities. A short-term program provides $12.5 million for states and tribes with plants decommissioning within three years of enactment. A long-term program, funded by a new Community Advisory Board Fund , requires licensees to pay $500,000 per plant into the fund when submitting a PSDAR that requires consultation. Beyond decommissioning planning, the bill provides significant economic assistance to nuclear host communities. It extends funding for economic development assistance and offers a 100% federal share for grants to small, rural, or disadvantaged nuclear host communities. A new noncompetitive grant program, administered by the Department of Energy, provides financial aid to local governments with stranded nuclear waste , calculated at $15 per kilogram of spent nuclear fuel. Furthermore, the bill mandates the creation of Host Community Economic Recovery Accounts for each covered facility, administered by the Secretary of Commerce. Licensees are required to annually transfer funds, ensuring the account balance is at least 2% of the combined decommissioning trust and recovery account. These funds are then used to provide grants to host communities for economic development planning and strategies, with no cost-sharing for disadvantaged communities.
