List of Approved Spent Fuel Storage Casks: FuelSolutionsTM Cask System Revision 4

The Nuclear Regulatory Commission (NRC) is amending its regulations revising the BNG Fuel Solutions Corporation (FuelSolutions TM ) cask system listing within the "List of approved spent fuel storage casks" to include Amendment No. 4 to Certificate of Compliance Number 1026. Amendment No. 4 will change Technical Specification (TS) requirements related to periodic monitoring during storage operations. Specifically, the amendment will revise the TS to permit longer surveillance intervals for casks with heat loads lower than the design basis heat load and permit visual inspection of the cask vent screens or measurement of the cask liner temperature to satisfy the periodic monitoring requirements that govern general design criteria for spent fuel storage casks. TS 3.3.1 will be deleted to remove daily monitoring requirements. TS 3.3.2 will be revised for the W21 and W74 canisters to permit either visual inspection of vent screens or liner thermocouple temperature monitoring. Also, TS 5.3.8 will add a section to the Periodic Monitoring Program which establishes intervals for periodic monitoring that are less than the time required to reach the limiting short-term temperature limit.
