In accordance with the provisions of 10 CFR 72.7, Specific Exemptions, Arizona Public Service Company (APS) requested an exemption from the provisions of 10 CFR 72.212(a)(2),

Specifically, an exemption was requested for the cask lid concrete design requirements in the NAC-MAGNASTOR Certificate of Compliance (CoC).

The requested exemption would apply to NAC-MAGNASTOR dry casks, described in the exemption request Enclosure of letter number 102-08416, that are or will be used by APS at PVNGS under CoC Amendment 7 listed in 10 CFR 72.214 (72-1031). By letter dated April 18, 2022, NAC International, Inc., the certificate holder for the NAC-MAGNASTOR system, responded to an NRC staff request for additional information (RAI) regarding the proposed revisions to the various amendments to the CoC (ADAMS Accession Number ML22108A197).

The NAC RAI response included proposed changes to the Technical Specifications (TS) and forms the regulatory and technical basis for the exemption request in letter number 102-08416. The proposed TS changes listed in Enclosure 1 to the NAC RAI response are met by APS, based upon NAC letter dated April 25, 2022 (Letter number ED20220065). APS intends to implement Revision 1 to Amendment 7 of the CoC, when final rulemaking is completed.
