The Nuclear Regulatory Commission (NRC) is amending its regulations revising the Standardized NUHOMS<Register> -24P and -52B cask system listing within the "List of Approved Spent Fuel Storage Casks" to include Amendment No. 3 to Certificate of Compliance (CoC) Number 1004. Amendment No. 3 will modify the present cask system design to add the -61BT dry storage canister (DSC), the storage portion of a dual purpose cask design intended to both store and transport spent fuel. The Technical Specifications are revised to add additional fuel parameters associated with use of the -61BT DSC. Additional administrative changes are made to the conditions of the CoC. However, the NRC is disapproving a portion of the applicant's request pertaining to storage of failed fuel.
