SUBJECT:
REQUEST FOR PUBLICATION IN BIWEEKLY FR NOTICE - NOTICE OF ISSUANCE OF AMENDMENT TO RENEWED FACILITY OPERATING LICENSE, FINAL DETERMINATION OF NO SIGNIFICANT HAZARDS CONSIDERATION, AND OPPORTUNITY FOR HEARING (EMERGENCY CIRCUMSTANCES) (CAC NO. MF8961)
Arizona Public Service Company, et al., Docket No. STN 50-530, Palo Verde Nuclear Generating Station, Unit No. 3, Maricopa County, Arizona Date of application for amendment: December 21, 2016, as supplemented by letter dated December 23, 2016. Brief description of amendment: The emergency amendment revised the Technical Specifications (TSs) for a one-time extension of the emergency diesel generator (DG) completion time described in TS 3.8.1.B.4. Specifically, the emergency amendment extended the TS required action 3.8.1.B.4 completion time from 10 days to 21 days for the purpose of collecting and analyzing data associated with the failure of train B DG and continuing with the repair of the DG. During surveillance testing on December 15, 2016, the DG suffered a failure of the number nine right cylinder connecting rod and piston. Current plans to collect and analyze data associated with the engine failure and continue with the repair will exceed the TS required action completion time of 10 days. As a result, the licensee evaluated the defense-in-depth and compensatory measures and is requesting a one-time deterministic license amendment to extend the completion time based upon the guidance of Standard Review Plan Biweekly Notice Coordinator Branch Technical Position 8-8, "Onsite (Emergency Diesel Generators) and Offsite Power Sources Allowed Outage Time Extensions." Date of issuance: December 23, 2016. Effective date: As of the date of issuance and shall be implemented prior to the expiration of the 10-days completion time, or December 25, 2016, at 3:56 AM PST.
