AGENCY:

Nuclear Regulatory Commission.

ACTION:

Direct final rule; confirmation of effective date.

SUMMARY:

The U.S. Nuclear Regulatory Commission (NRC) is confirming the effective date of October 17, 2023, for the direct final rule that was published in the Federal Register on August 3, 2023.

The renewal of the initial certificate and Amendment Nos. 1 through 8 revises the certificate of compliance's conditions and technical specifications to address aging management activities related to the structures, systems, and components important to safety of the dry storage system to ensure that these will maintain their intended functions during the period of extended storage operations.
