McGuire Nuclear Station, Units 1 and 2 Docket Nos. 50-369, 50-370 Renewed License Nos. NPF-9 and NPF-17 Independent Spent Fuel Storage Installation (ISFSI) Docket No. 72-1031 Exemption Request for NAC MAGNASTOR Cask Loaded to Incorrect Helium Backfill Density Pursuant to 10 CFR 72.7, "Specific Exemptions," Duke Energy Carolinas, LLC (Duke Energy) requests a one-time exemption from the requirements of 10 CFR 72.212(b )(3), 10 CFR 72.212(b)(5)(i), and 10 CFR 72.212(b)(11) for NAC MAGNASTOR Cask OFCTKN045 due to a non-compliance with the terms and conditions of the NAC MAGNASTOR Certificate of Compliance (CoC) No. 1031, Amendment 7, at the time of cask loading. 10 CFR 72.212(b)(3),

10 CFR 72.212(b)(5)(i), and 10 CFR 72.212(b)(11) require, in part, conformance to the terms, conditions, and specifications of Coe No. 1031.

On June 4, 2018, recently loaded MAGNASTOR Cask OFCTKN045 was transported to the McGuire Nuclear Station (MNS) Independent Spent Fuel Storage Installation (ISFSI) storage pad area. Subsequently, Duke Energy was reviewing various technical details of the completed loading procedure and noticed that during the helium backfill process, the two helium mass flow meters measured significantly different volumes. While small deviations are normal, significant deviations had not been previously observed.

Further review of the helium backfill data revealed the cask helium density within MAGNASTOR Cask OFCTKN045 exceeded the helium density range presented in MAGNASTOR Technical ;J4 .'l>l'.d, Suit~ 2ll0 NAC INTER.NA 'fIONAL AFFJ.DA \rIT PURSUANT TO 10 CFR 2.390 George C:nrver {Affiant}, Vite President, Engineering and Licensing, bereinafrer re;ferr"ed to as N AC, at 393-0 East Jones Brkl:,gc Road,, Non::lin:ss, Gei,irgia 100~2, being d!lily swor11, de-poses and s:ays that:
