These changes improve safety checks, clarify technical details, and correct typos. The new rules take effect March 19, 2025, affecting nuclear facilities using this storage system with no expected extra costs. ## Abstract The U.S. Nuclear Regulatory Commission (NRC) is amending its spent fuel storage regulations by revising the NAC International, Inc. MAGNASTOR[supreg] 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 is also correcting typographical errors in Revision 1 to Amendment Nos. 11 to 13 and Amendment No. 14 to Certificate of Compliance No. 1031. ## Effects PRIA read - Approved use of MAGNASTOR® under general license: benefit, medium. If your nuclear power plant holds a general license under 10 CFR part 72, you may load spent nuclear fuel into NAC International MAGNASTOR® casks that meet the revised Certificate of Compliance Nos. 0 through 13 and new Amendment No. 14. The rule becomes effective March 19, 2025. - Six-month implementation and written checks: cost, low. General licensees using the revised Certificate of Compliance must implement the revised certificates within 6 months and perform written evaluations in accordance with 10 CFR 72.212(b)(5) to show casks conform to the revised terms. The 6-month timeframe is described as a standard implementation pe… - Amendment 14 applies only to new casks: benefit, low. Amendment No. 14 applies only to new MAGNASTOR® casks fabricated and used under Amendment No. 14; existing users continue to be covered by Amendment No. 13 and are not required to adopt Amendment No. 14 but may do so voluntarily. This distinction is stated in the rule text. - No significant environmental or dose changes: benefit, low. The NRC determined that implementing Amendment No. 14 and revisions to Amendments 0 through 13 will not significantly change effluent releases, occupational or offsite radiation doses, or the potential for radiological accidents. The finding of no significant impact supports that an environmental i… - No significant impact on small entities: benefit, low. The NRC certifies under the Regulatory Flexibility Act that this direct final rule will not have a significant economic impact on a substantial number of small entities; the rule affects only nuclear power plant licensees and NAC International, Inc. and those entities are not small under NRC size s… ## Related documents - [2026-20736](https://policyrisk.com/federal-register/2026-20736): Air Plan Approval; Michigan; Clean Data Determination for the Berrien, MI and Muskegon, MI Areas for the 2015 Ozone Standards, 2026-10-09 - [2026-20757](https://policyrisk.com/federal-register/2026-20757): Schedules of Controlled Substances; Removal of Exemption Status for Inactive Butalbital Products, 2026-10-09 - [2026-20727](https://policyrisk.com/federal-register/2026-20727): Medical Devices; Immunology and Microbiology Devices; Classification of the System for Detection of Nucleic Acid From Non-Viral Microorgani…, 2026-10-09 - [2026-20792](https://policyrisk.com/federal-register/2026-20792): Raisins Produced From Grapes Grown in California; Order Amending Marketing Order No. 989, 2026-10-09 - [C1-2026-20019](https://policyrisk.com/federal-register/C1-2026-20019): Fisheries of the Exclusive Economic Zone Off Alaska; Groundfish Reserves in the Bering Sea and Aleutian Islands Management Area, 2026-10-09 - [2026-20748](https://policyrisk.com/federal-register/2026-20748): Schedules of Controlled Substances: Placement of O-Desmethyltramadol in Schedule I; Correction, 2026-10-09 ## Sources - [2024-31095 on federalregister.gov](https://www.federalregister.gov/documents/2025/01/03/2024-31095/list-of-approved-spent-fuel-storage-casks-nac-international-inc-magnastor-storage-system-certificate) - [2024-31095 as published (PDF)](https://www.govinfo.gov/content/pkg/FR-2025-01-03/pdf/2024-31095.pdf) ## Related - [Previous: 2024-31031, Program Integrity and Institutional Quality: Distance Education and Return of T…](https://policyrisk.com/federal-register/2024-31031) - [Next: 2024-31242, Practice and Procedure: Rules of General Application, Safeguards, Antidumping a…](https://policyrisk.com/federal-register/2024-31242) - [All Federal Register documents](https://policyrisk.com/federal-register) Source: PRIA, https://policyrisk.com/federal-register/2024-31095 (as of 2026-06-11).
