The U.S. Nuclear Regulatory Commission (NRC) is amending its spent fuel storage regulations by revising the NAC International NAC- UMS[supreg] Universal Storage System listing within the "List of approved spent fuel storage casks" to include Amendment No. 8 to Certificate of Compliance No. 1015. Amendment No. 8 revises the certificate of compliance to: Add the storage of damaged boiling-water reactor spent fuel, including higher enrichment and higher burnup spent fuel; change the allowable fuel burnup range; expand the boiling-water reactor class 5 fuel inventory that could be stored in the cask; and revise definitions in the technical specifications.
