On May 10, 2007 (72 FR 26535), 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. 5 to CoC No. 1025. This amendment revises Technical Specifications to incorporate changes to the reporting and monitoring requirements, to incorporate guidance from NRC Interim Staff Guidance-22, and to include editorial changes for clarity. The amendment also revises the CoC description to remove the requirement for tamper-indicating devices on the Vertical Concrete Casks. In the direct final rule, NRC stated that if no significant adverse comments were received, the direct final rule would become final on July 24, 2007. The NRC did not receive any comments that warranted withdrawal of the direct final rule. Therefore, this rule will become effective as scheduled.
