The proposed changes would revise TS 4.2.1, "Reactor Core, Fuel Assemblies," and TS 5.6.5.b, "Core Operating Limits Report (COLA)," and allow the use of Combustion Engineering 16x16 NGF clad with the Optimized ZIRLOŽ material in PVNGS, Units 1, 2, and 3. To support the fuel transition, APS also requested an exemption from certain requirements of Title 1 O of the Code of Federal Regulations (1 O CFR), Part 50, Section 1 O CFR 50.46 and 1 O CFR 50 Appendix K to allow the use of Optimized ZIRLOŽ as a cladding material in PVNGS, Units 1, 2, and 3. The U.S. Nuclear Regulatory Commission (NRG) staff conducted a regulatory audit on November 2-3, 2016, to focus the staff's requests for additional information and enhance technical understanding of the submitted documentation.

By letter dated July 1, 2016 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML 16188A336), Arizona Public Service Company (APS, the licensee) requested changes to the Technical Specifications (TSs) to support the implementation of next generation fuel (NGF) for PVNGS, Units 1, 2, and 3. The proposed changes would revise TS 4.2.1, "Reactor Core, Fuel Assemblies," and TS 5.6.5.b, "Core Operating Limits Report (COLR),'' and will allow the use of Combustion Engineering (CE) 16x16 NGF clad with the Optimized ZIRLOŽ material in PVNGS, Units 1, 2, and 3. To support the fuel transition, APS also requested an exemption from certain requirements of Title 1 O of the Code of Federal Regulations (1 O CFR) Section 50.46, "Acceptance criteria for emergency core cooling systems [ECCS] for light-water nuclear power reactors,'' and 10 CFR Part 50, Appendix K, "ECCS Evaluation Models," to allow the use of Optimized ZIRLOŽ as a cladding material in PVNGS, Units 1, 2, and 3. The NRC staff conducted a regulatory audit on November 2-3, 2016, to focus the staff's requests for additional information (RAls) and enhance technical understanding of the submitted documentation. During this audit, it was determined that further time would be needed to examine materials related to the statistical methodology proposed for analyzing the fuel assembly misload event and the use of SKBOR code in the boric acid precipitation analysis that were provided during the audit, but not originally available as part of the submittal. Additionally, the NRC staff requested justification for the proposed penalty to address the lack of treatment of thermal conductivity degradation (TCD) in the FATES-3B code. Therefore, the NRC staff has proposed to conduct a second regulatory audit at this point in the review process in an effort to resolve or focus the questions that arose from further consideration of the outstanding issues, and to observe the justification for the proposed TCD penalty. This audit will help the NRC staff better understand the supporting documentation and analysis results through interaction with APS's technical experts and will help to focus the staff's RAls on those questions where docketed information is needed to complete the review.

Dear Mr. Bement:
By letter dated July 1, 2016 (Agencywide Documents Access and Management System Accession No. ML 16188A336), Arizona Public Service Company (APS) requested changes to the Technical Specifications (TSs) to support the implementation of next generation fuel (NGF) for Palo Verde Nuclear Generating Station (PVNGS), Units 1, 2, and 3. The proposed changes would revise TS 4.2.1, "Reactor Core, Fuel Assemblies," and TS 5.6.5.b, "Core Operating Limits Report (COLA)," and allow the use of Combustion Engineering 16x16 NGF clad with the Optimized ZIRLOŽ material in PVNGS, Units 1, 2, and 3. To support the fuel transition, APS also requested an exemption from certain requirements of Title 1 O of the Code of Federal Regulations (1 O CFR), Part 50, Section 1 O CFR 50.46 and 1 O CFR 50 Appendix K to allow the use of Optimized ZIRLOŽ as a cladding material in PVNGS, Units 1, 2, and 3. The U.S. Nuclear Regulatory Commission (NRG) staff conducted a regulatory audit on November 2-3, 2016, to focus the staff's requests for additional information and enhance technical understanding of the submitted documentation. During this audit, it was determined that further time would be needed to examine materials related to the statistical methodology proposed for analyzing the fuel assembly mislead event and the use of SKBOR code in the boric acid precipitation analysis that were provided during the audit, but not originally available as part of the submittal. Additionally, the NRC staff requested justification for the proposed penalty to address the lack of treatment of thermal conductivity degradation in the FATES-3B code. As a result, the NRG staff will conduct another audit at the EXCEL facility in Rockville, Maryland, on March 8, 2017. The Enclosure to this letter provides an audit plan in support of this audit.
