The Nuclear Regulatory Commission (NRC) is amending its regulations by revising the Holtec International HI-STAR 100 cask system listing within the "List of approved spent fuel storage casks" to include Amendment No. 2 to the Certificate of Compliance (CoC). Amendment No. 2 revises the HI-STAR 100 cask system Appendix B of the Technical Specifications (TS), Item 1.4.6, "Specific Parameters and Analysis for the Storage Pad and Foundation" to simplify the language of this specification. The current 60-g limit for cask drop and tipover events in TS Item 1.4.6 would remain unchanged. This amendment will allow the holders of power reactor operating licenses to store spent fuel in the HI-STAR 100 cask system, as amended, under a general license.
