List of Approved Spent Fuel Storage Casks: Standardized NUHOMS®-24P, -52B, -61BT, -32PT, -24PHB, and -24PTH Revision
The Nuclear Regulatory Commission (NRC) is amending its regulations revising the Transnuclear, Inc., Standardized NUHOMS[reg] System listing within the "List of approved spent fuel storage casks" to include Amendment No. 8 to Certificate of Compliance Number (CoC No.) 1004. Amendment No. 8 to the Standardized NUHOMS[reg] System CoC will modify the cask design by adding a new spent fuel storage and transfer system, designated the NUHOMS[reg]-24PTH System. The NUHOMS[reg]-24PTH System consists of new or modified components: The -24PTH dry shielded canister (DSC); a new -24PTH DSC basket design; a modified horizontal storage module (HSM), designated the HSM-H; and a modified transfer cask (TC), designated the OS 197FC TC. The NUHOMS[reg]-24PTH System is designed to store fuel with a maximum average burnup of up to 62 gigawatts-day/metric ton of uranium; maximum average initial enrichment of 5.0 weight percent; minimum cooling time of 3.0 years; and maximum heat load of 40.8 kilowatts per DSC, under a general license.
