Subject:

Palo Verde Nuclear Generating Station Units 1, 2, and 3 Docket Nos. STN 50-528/529/530 Fourth 10-Year Interval Pump and Valve Inservice Testing Program Relief Requests PRR-01, PRR-02, PRR-03, PRR-04, PRR-05, and PRR-06, Adoption of 2012 Edition of the American Society of Mechanical Engineers Operation and Maintenance Code Pursuant to 10 CFR 50.55a, APS has revised the Palo Verde Nuclear Generating Station (PVNGS) pump and valve inservice testing (1ST) program for the fourth 10-year interval for Units 1, 2, and 3, which begins on January 15, 2018. Reference 1 transmitted the relief requests that APS considered required for the fourth 10-year interval.

In Reference 2, APS withdrew relief requests GRR-01, and GRR-02 of Reference 1 which related to the use of the 2012 Edition of the American Society of Mechanical Engineers (ASME) Operation and Maintenance (OM) Code and Code Case OMN-20, Inservice Test Frequency, which is an alternative to the frequency specifications of the ASME OM Code.

This action was due to the 2012 Edition of the ASME OM Code rulemaking for 10 CFR 50.55a not being finalized. In addition, APS requested that the remaining relief requests be reviewed based upon the existing ASME OM Code of record in 10 CFR 50.55a, which was the 2004 Edition and 2006 Addenda, in lieu of the 2012 Edition.

In Federal Register Notice (82FR136), dated July 18, 2017, the relevant final rule was published that incorporated the 2012 Edition of the ASME OM Code into 10 CFR 50.55a, including Code Case OMN-20, with an effective date of August 17, 2017.

Adoption of 2012 Edition of the ASME OM Code Page 2 As Indicated In References 1 and 2, APS plans to use the 2012 Edition of the OM Code for the fourth 10-year 1ST Interval for PVNGS Units 1, 2 and 3, and hereby requests that the remaining relief requests be reviewed pursuant to the 2012 ASME OM Code.

No new commitments are being made In this submittal.
