(Entergy) submitted decommissioning funding plans (DFPs) for the Grand Gulf Nuclear Station Independent Spent Fuel Storage Installation (ISFSI), located in Claiborne County, Mississippi, for U.S. Nuclear Regulatory Commission (NRC) staff review and approval. The NRC staff is currently reviewing these updated DFPs submitted by Entergy.

The NRC regulations at Title 10 of the Code of Federal Regulations (10 CFR) Part 72, Licensing Requirements for the Independent Storage of Spent Nuclear Fuel, High-Level Radioactive Waste, and Reactor-Related Greater than Class C Waste, govern the storage of spent nuclear fuel (spent fuel) generated at commercial nuclear power reactors licensed by the NRC. Spent fuel that has been removed from the reactors spent fuel pool is typically stored at a nuclear power plants ISFSI.

The NRC requires its licensees to plan for the eventual decommissioning of their licensed facilities prior to license termination.

The final rule amended the NRC regulation, 10 CFR 72.30, which concerns financial assurance and decommissioning for ISFSIs.
