On March 15, 2002 (67 FR 11566), the NRC published in the Federal Register a direct final rule amending its regulations in part 72 by 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) No. 1025. This amendment allows for modification of the design of the cask system to accommodate a new type of fuel. The modifications include increased length of the fuel basket and canister, transfer cask, and vertical concrete cask. Changes 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 has been revised in its entirety to include a reference to the new type of fuel and a revised format. The Technical Specifications (TS) have also been 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. In the direct final rule, NRC stated that if no significant adverse comments were received, the direct final rule would become final on May 29, 2002. The NRC did not receive any comments on the direct final rule. Therefore, this rule will become effective as scheduled.
