MAGNASTOR® Storage System listing within the “List of approved spent fuel storage casks” to include Amendment No. 14 and revisions to Amendment Nos. 0 through 13 to Certificate of Compliance No. 1031. Amendment No. 14 and revisions to Amendment Nos. 0 through 13 revise the certificate of compliance to add a revised method of evaluation for the non-mechanistic tipover accident, clarify in the technical specifications that damaged missing grid spacers only apply to pressurized-water reactor fuel assembles, clarify inlet and outlet vent blockage and surveillance requirements in limiting condition for operation 3.1.2 in Appendix A to the certificate of compliance and associated technical specification bases, and remove the reference to Type II Portland cement in the description of the certificate of compliance. The NRC also corrected typographical errors. 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 19, 2025. The NRC received and docketed one comment on the companion proposed rule (90 FR 268; January 3, 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-2024-0180 and is also available in ADAMS under Accession No. ML25037A135. 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: February 12, 2025.</DATED> For the Nuclear Regulatory Commission. <NAME>Pamela S.
