Multi-Purpose Canister System listing within the “List of approved spent fuel storage casks” to include Amendment No. 9 and revision to Amendment Nos. 6, 7, and 8. Amendment No. 9 and revision to Amendment Nos. 6, 7, and 8 revises the description of the vertical concrete cask (VCC) in the certificate of compliance and technical specifications to make a distinction between the VCC body and the VCC lid, in terms of applicability of the American Concrete Institute (ACI) Specifications ACI 349 and ACI 318. In the direct final rule, the NRC stated that if no significant adverse comments were received, the direct final rule would become effective on May 13, 2025. The NRC received and docketed one comment on the companion proposed rule (90 FR 10799; February 27, 2025). An electronic copy of the comment can be obtained from the Federal Rulemaking website at <E T="03">https://www.regulations.gov</E> under Docket ID NRC-2024-0200 and is also available in ADAMS under Accession No. ML25090A312. The NRC evaluated the comment against the criteria described in the direct final rule and determined that the comment was not significant and adverse. Specifically, the comment was outside the scope of this rulemaking and did not oppose the rule; propose a change or an addition to the rule; or cause the NRC to make a change to the rule, the certificate of compliance, or the technical specifications. Therefore, this direct final rule will become effective as scheduled. <SIG> <DATED>Dated: April 9, 2025.</DATED> For the Nuclear Regulatory Commission. <NAME>Araceli Billoch Colon,</NAME> Chief, Regulatory Analysis and Rulemaking Support Branch, Division of Rulemaking, Environmental, and Financial Support, Office of Nuclear Material Safety and Safeguards. </SIG> </SUPLINF> <FRDOC>[FR Doc. 2025-06315 Filed 4-11-25; 8:45 am]</FRDOC> </RULE>
