List of Approved Spent Fuel Storage Casks: TN Americas, LLC Standardized NUHOMS® Horizontal Modular Storage System for Irradiated Nuclear Fuel, Certificate of Compliance No. 1004, Renewed Amendment No. 19

The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its spent fuel regulations by revising the TN Americas, LLC Standardized NUHOMS[supreg] Horizontal Modular Storage System for Irradiated Nuclear Fuel listing within the "List of approved spent fuel storage casks" to include Renewed Amendment No. 19 to Certificate of Compliance (CoC) No. 1004. The NRC is referring to this amendment as "Renewed Amendment No. 19" because it was submitted after the renewal of the TN Americas, LLC Standardized NUHOMS Horizontal Modular Storage System for Irradiated Nuclear Fuel Certificate of Compliance No. 1004 and, therefore, subject to the Aging Management Program requirements of the renewed certificate. Renewed Amendment No. 19 would amend the certificate of compliance to provide for a 61BTH improved basket design using staggered plates similar the 24PTH Type 3 basket approved in CoC 1004 Amendment 18 and similar to the EOS 37PTH and 89BTH baskets approved in CoC 1042. This would simplify construction, reduce weight and improve fabricability. Additional changes are proposed to address editorial corrections, consistency, and terminology clarifications.

Southern Nuclear Operating Company; Vogtle Electric Generating Plant Units 1 & 2; Independent Spent Fuel Storage Installation; Exemption

The U.S. Nuclear Regulatory Commission (NRC) has issued a one- time exemption to Southern Nuclear Operating Company (SNC), authorizing Vogtle Electric Generating Plant Units 1 and 2 (Vogtle 1 and 2) to retain a single Neutron Source Assembly (NSA) in its current storage cell within a multi-purpose canister ((MPC-32), serial number MPC-707) at the Vogtle Independent Spent Fuel Storage Installation, in a manner that is inconsistent with the loading restrictions specified in Certificate of Compliance (CoC) No. 1014, Amendment 11, for the HI- STORM 100S Version B dry storage system. The exemption allows the NSA to remain in a peripheral basket cell, contrary to Appendix B, Table 2.1-1, which restricts NSA containing assemblies to designated interior cells. The NRC's determination is based on SNC's safety evaluation and supporting analyses demonstrating that the configuration continues to meet applicable safety requirements for criticality control, shielding, thermal performance, structural integrity, and confinement.
