The U.S. Nuclear Regulatory Commission (NRC) has amended its spent fuel storage regulations, updating the NAC Multi-Purpose Canister (NAC-MPC) System to include a new Amendment No. 9 and revisions to Amendments 6, 7, and 8 for Certificate of Compliance No. 1025. This change clarifies the design and technical specifications of the NAC-MPC System, particularly regarding distinctions between the vertical concrete cask body and lid. The changes do not significantly alter the cask's design, ensuring it remains safe in the event of accidents, and public health and safety continue to be protected. This rule will be effective on May 13, 2025, unless significant objections are raised.
Simple Explanation
The government updated some rules about how to store used nuclear fuel safely. They tweaked the instructions for a special container to make sure it stays safe, and everything's still fine if something goes wrong.
