## Abstract

The U.S. Nuclear Regulatory Commission (NRC or the Commission) is amending its spent fuel storage regulations by revising the NAC International, Inc. (NAC) MAGNASTOR [supreg] System listing within the "List of Approved Spent Fuel Storage Casks" to include Amendment No. 2 to Certificate of Compliance (CoC) Number 1031. Amendment No. 2 will revise: Technical Specification (TS) 3.3.2 to reduce the transportable storage canister removable surface contamination limits; TS 4.1.1 to add various boron-10 areal densities for use with Pressurized Water Reactor and Boiling Water Reactor baskets and to replace the fuel tube orthogonal pitch with the minimum fuel tube outer diagonal dimension; Table 2.1-2, "ASME Code Alternatives for MAGNASTOR [supreg] components," of the Final Safety Analysis Report to correct the code reference; and Appendices A and B of the TSs to make editorial corrections.
