On July 18, 2003 (68 FR 42570), the NRC published a direct final rule amending its regulations in 10 CFR part 72 to revise the NAC-MPC cask system listing within the “List of Approved Spent Fuel Storage Casks” to include Amendment No. 3 to CoC No. 1025. This amendment incorporates changes in support of the Yankee Nuclear Power Station (Yankee Rowe) fuel loading campaign and makes corrections to the Connecticut Yankee technical specifications. Specifically, the amendment incorporates fuel enrichment tolerances; incorporates 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); revises the average surface dose rate limits for the concrete cask; incorporates administrative changes in the ASME Code Alternatives; corrects the Connecticut Yankee tables for fuel assembly limits and intact fuel assembly characteristics; and incorporates editorial and administrative changes in the CoC. In the direct final rule, NRC stated that if no significant adverse comments were received, the direct final rule would become final on October 1, 2003. The NRC did not receive any comments that warranted withdrawal of the direct final rule. Therefore, this rule will become effective as scheduled.
