McGuire Nuclear Station, Units 1 and 2 Docket No. 50-369 and 50-370 Supplement to Non-Voluntary License Amendment Request (LAR) to Correct Non-Conservative Technical Specification 3.4.11 - PORVs By letter dated February 26, 2018, Duke Energy submitted a LAR for the McGuire Nuclear Station, Unit 1 Renewed Operating License NPF-9, and Unit 2 Renewed Operating License NPF-17. Specifically, this LAR was requested to correct Non-Conservative Technical Specification 3.4.11, "Pressurizer Power Operated Relief Valves (PORVs)."

Enclosure 2 (Marked Technical Specification Pages) and Enclosure 3 (Clean Technical Specification Pages) of the above LAR contained some typographical errors. The Note for SR 3.4.11.1 in Enclosure 2 should have referred to Condition F instead of Condition E. The Note for new Condition Kin Enclosure 3 should have referred to Required Action F.2 instead of Required Action E.2. The Note for SR 3.4.11.1 in Enclosure 3 should have referred to Condition F instead of Condition E.

The purpose of this supplement is to provide the replacement pages to correct the errors as described above. This supplement contains no NRC commitments and does not impact the No Significant Hazards Consideration Determination Analysis included in the February 26, 2018 submittal. If you have any questions, please contact P.T. Vu at (980) 875-4302.

I declare under penalty of perjury that the foregoing is true and correct. Executed on September 13, 2018.
