List of Approved Spent Fuel Storage Casks: HI-STORM 100 Revision 3
The Nuclear Regulatory Commission (NRC) is amending its regulations by revising the Holtec International HI-STORM 100 cask system listing within the ``List of approved spent fuel storage casks'' to include Amendment No. 3 to Certificate of Compliance Number 1014. Amendment No. 3 revises Technical Specification (TS) 3.1.3, to eliminate cooling of the Multi-Purpose Canister (MPC) cavity prior to reflood with water, as part of cask unloading operations; TS 3.3.1, to allow linear interpolation between minimal soluble boron concentrations, for certain fuel enrichments in the MPC-32/32F; Appendix B, Section 1 to the CoC, to make modifications to the definitions of fuel debris, damaged fuel assembly, and non-fuel hardware; and Appendix B, Section 2 to the CoC, to permit the storage of pressurized water reactor fuel assemblies with annular fuel pellets in the top and bottom 12 inches of the active fuel length. Other changes are made to incorporate minor editorial corrections. This final rule allows the holders of power reactor operating licenses to store spent fuel in this approved cask in accordance with the revised conditions, under the NRC's general license provisions.
