List of Approved Spent Fuel Storage Casks: NAC-MPC Revision

The Nuclear Regulatory Commission (NRC) is proposing to amend its regulations revising the NAC International, Inc., Multipurpose Canister cask system listing within the "List of Approved Spent Fuel Storage Casks" to include Amendment No. 3 to the Certificate of Compliance (CoC). This amendment would incorporate changes in support of the Yankee Nuclear Power Station (Yankee Rowe) fuel loading campaign and make corrections to the Connecticut Yankee technical specifications. Specifically, the amendment would incorporate fuel enrichment tolerances; incorporate fuel assemblies with up to 20 damaged fuel rods, recaged assemblies, the Yankee Rowe damaged fuel can, and assembly weights up to 432 kilograms (950 pounds); revise the average surface dose rate limits for the concrete cask; incorporate administrative changes in the American Society of Mechanical Engineers (ASME) Code Alternatives; correct the Connecticut Yankee tables for fuel assembly limits and intact fuel assembly characteristics; and incorporate editorial and administrative changes in the CoC.
