SUPPLEMENTARY INFORMATION:

On December 18, 2018 (83 FR 64729), the NRC published a direct final rule amending its regulations in part 72 of title 10 of the Code of Federal Regulations by revising the “List of approved spent fuel storage casks” to include Amendment Nos. 7 and 8 to Certificate of Compliance No. 1025 for the NAC-MPC Storage System. Amendment No. 7 revises the technical specifications to eliminate the requirements for the heat removal system to be operable for La Crosse Boiling Water Reactor spent fuel stored in the NAC-MPC because convective cooling is not required, and to eliminate duplicative requirements. In addition, Amendment No. 8 removes duplicative surveillance requirements in the technical specifications because these requirements are already required by the revised Technical Specification A 3.1.6, “CONCRETE CASK Heat Removal System.”

In the direct final rule, the NRC stated that if no significant adverse comments were received, the direct final rule would become effective on March 4, 2019. As described more fully in the direct final rule, a significant adverse comment is a comment where the commenter explains why the rule would be inappropriate, including challenges to the rule's underlying premise or approach, or would be ineffective or unacceptable without a change. Because no significant adverse comments were received, the direct final rule will become effective as scheduled.
