The Nuclear Regulatory Commission (NRC) is amending its regulations revising the BNFL Fuel Solutions (FuelSolutions<SUP>TM</SUP>) cask system listing within the "List of approved spent fuel storage casks" to include Amendment No. 3 to Certificate of Compliance Number 1026. Amendment No. 3 will modify the Technical Specifications. The current Technical Specifications require that if the W-21 canister is required to be removed from its storage cask, then the canister must be returned to the spent fuel building. The modified Technical Specifications will provide an alternative to returning the canister to the spent fuel building by returning it to the transfer cask. Specifically, Technical Specifications 3.3.2 and 3.3.3 propose returning the W-21 canister to the transfer cask while restoring normal storage conditions. The amendment also includes several editorial changes to Technical Specifications 3.1.1, 3.3.2, and 3.3.3.
