List of Approved Spent Fuel Storage Casks: NAC-MPC Revision

The Nuclear Regulatory Commission (NRC) is proposing to amend its regulations revising the NAC International Multi-Purpose Canister (NAC-MPC) cask system listing within the "List of Approved Spent Fuel Storage Casks" to include Amendment 2 to Certificate of Compliance (CoC) Number 1025. This amendment would allow for modification of the design of the cask system to accommodate a new type of fuel. The NAC-MPC system component modifications would include increased length of the fuel basket and canister, transfer cask, and vertical concrete cask. Changes would also include a redesigned fuel basket to accommodate 26 fuel assemblies, with an alternate 24-fuel assembly configuration and increased transfer cask radial shielding. The CoC would be revised in its entirety to include a reference to the new type of fuel and a revised format. The Technical Specifications (TS) would also be revised in their entirety to include specifications for the new type of fuel, new operational limits, and to incorporate a revised format for the TS.
