The U.S. Nuclear Regulatory Commission (NRC) is amending its spent fuel storage regulations by revising the TN Americas LLC, NUHOMS[supreg] EOS Dry Spent Fuel Storage System listing within the "List of approved spent fuel storage casks" to include Amendment No. 2 to Certificate of Compliance No. 1042. Amendment No. 2 revises the certificate of compliance to add a dry shielded canister for storage, add new heat load zone configurations, and make other changes to the storage system. Amendment No. 2 also changes the certificate of compliance, technical specifications, and updated final safety analysis report for consistency and clarity.
