Résumé

The U.S. Nuclear Regulatory Commission (NRC) is confirming the effective date of June 17, 2020, for the direct final rule that was published in the Federal Register on April 3, 2020. The direct final rule amends the NRC's 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. 1 to Certificate of Compliance No. 1042. Amendment No. 1 makes the following changes: Adds a new basket type (Type 4) to allow for the loading of intact, damaged, or failed fuel; adds another new basket type (Type 5); accepts fuel assemblies with a minimum two-year cooling time, in selected locations within the basket; and adds the NUHOMS[supreg] MATRIX design as an alternative to the EOS horizontal storage module design for the storage of spent fuel. Amendment No. 1 also makes other additional revisions to the certificate of compliance and the technical specifications for consistency and clarity.
