1.0 INTRODUCTION

By application dated September 27, 2013 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML13280A264), as supplemented by letter dated December 12, 2013 (ADAMS Accession No. ML13352A007), Arizona Public Service Company (APS, the licensee) requested changes to the Technical Specifications (TSs) for Palo Verde Nuclear Generating Station (PVNGS), Units 1, 2, and 3, to reinstate an inadvertently omitted 4-hour completion time within TS 3.3.3, "Control Element Assembly Calculators (CEACs)," and to revise a test frequency note within a Surveillance Requirement (SR) under TS 3.3.6, "Engineered Safety Features Actuation System (ESFAS) Logic and Manual Trip." The supplemental letter dated December 12, 2013, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the U.S. Nuclear Regulatory Commission (NRC) staff's original proposed no significant hazards consideration determination as published in the Federal Register on February 4, 2014 (79 FR 6640).

The licensee requested a TS change to reinstate the 4-hour completion time in TS 3.3.3, "Control Element Assembly Calculators (CEACs)," Required Action B.2.2 that was inadvertently omitted in the license amendment request (LAR) dated September 17, 2003 (ADAMS Accession No. ML032670629), for Amendment No. 152, dated March 23, 2004 (ADAMS Package Accession No. ML040860597). This change restores the 4-hour completion time for Required Action B.2.2 that existed prior to being inadvertently omitted.

The licensee also requested to modify the Note within SR 3.3.6.2 under TS 3.3.6, "Engineered Safety Features Actuation System (ESFAS) Logic and Manual Trip," which states "Relays exempt from testing during operation shall be tested each 18 months." The licensee proposes to replace "18 months" with "in accordance with the Surveillance Frequency Control Program" in the Note. The change would make the Note consistent with the Frequency of SR 3.3.6.2, which states, "In accordance with the Surveillance Frequency Control Program," and was last revised Enclosure 4

when Amendment No. 188 was issued to reflect the adoption of Technical Specifications Task Force (TSTF) change travel TSTF-425, Revision 3, "Relocate Surveillance Frequencies to Licensee Control- RITSTF [Risk-Informed TSTF] Initiative 5b," dated December 15, 2011

{ADAMS Accession No. ML112620293).

2.0 REGULATORY EVALUATION

The regulations in Title 10 of the Code of Federal Regulations (1 0 CFR) 50.36, "Technical specifications," provide the regulatory requirements for the contents in a licensee's TSs. This regulation requires that the TSs include items in the following five specific categories related to station operation. These categories include (1) safety limits, limiting safety system settings, and limiting control settings; (2) limiting conditions for operation; (3) SRs; (4) design features; and (5) administrative controls. The regulation does not specify the particular requirements to be included in a plant's TSs. For item (3), 10 CFR 50.36(c)(3) notes that SRs are requirements relating to test, calibration, or inspection to assure that necessary quality of systems and components is maintained.

In general, there are two classes of changes toTS: (1) changes needed to reflect modifications to the design bases (TS are derived from the design basis), and (2) voluntary changes to take advantage of the evolution in policy and guidance as to the required contents and preferred format of TS over time. This amendment deals with the second class of changes. In determining the acceptability of revising TS 3.3.3, "Control Element Assembly Calculators (CEACs)," Required Action 8.2.2 and revising the Note to SR 3.3.6.2, the NRC staff used the accumulation of generically approved guidance in NUREG-1432, "Standard Technical Specifications, Combustion Engineering Plants, Revision 4.0," dated April2012 (ADAMS Accession No. ML12102A165) as modified by TSTF-425, "Relocate Surveillance Frequencies to Licensee Control- RITSTF Initiative 5b," dated March 18, 2009 (ADAMS Accession No. ML090850642).

3.0 TECHNICAL EVALUATION

The NRC staff has reviewed the licensee's regulatory and technical analyses in support of its proposed license amendment which are described in Section 3 and 4 of the licensee's submittal. The NRC staff's evaluation is provided below:

3.1 Reinstate a 4-hour Completion Time in TS 3.3.3, Required Action 8.2.2 The proposed change toTS 3.3.3, Required Action 8.2.2, reinstates a 4-hour completion time which was inadvertently omitted by the licensee in aLAR dated September 17, 2003, which supported replacement of part length control element assemblies (CEAs) with a new CEA design described as part strength CEA. TS 3.3.3 Required Action 8.2.2 states that Verify all full strength and part strength control element assembly (CEA) groups are fully withdrawn and maintained fully withdrawn, except during Surveillance testing pursuant to SR 3.1.5.3 or for control, when CEA group #5 may be inserted to a maximum of 127.5 inches withdrawn.

When the licensee made an editorial change to TS 3.3.3 in the 2003 LAR, the Completion Time for Required Action 8.2.2 (previously numbered 8.2) was inadvertently deleted. As a result, the 4-hour completion time was not included for Required Action 8.2.2 in proposed changes for Amendment No. 152 issued to the licensee on March 23, 2004 and was not addressed in the safety evaluation issued with Amendment No.1 52.

The proposed change corrects the unlimited completion time in TS 3.3.3, Required Action 8.2.2 by reinstating the 4-hour completion time that existed for Required Action 8.2.2 (previously numbered 8.2) prior to issuance of Amendment No. 152. This corrective change is conservative and consistent with the 4-hour completion time for the other Required Actions under 8.2. Therefore, the NRC staff concludes that this change is acceptable.

3.2 Revise a Note within a Surveillance Requirement in TS 3.3.6 The licensee proposes to revise the SR 3.3.6.2 Note for testing actuation logic subgroup relays.

The current Note under SR 3.3.6.2 states that Relays exempt from testing during operation shall be tested each 18 months.

The revised Note under SR 3.3.6.2 would state that Relays exempt from testing during operation shall be tested in accordance with the Surveillance Frequency Control Program.

The change would make the Note consistent with the Frequency of SR 3.3.6.2 for testing actuation logic subgroup relays, which states, "In accordance with the Surveillance Frequency Control Program," which was issued with Amendment No. 188 to adopt TSTF-435, in response to the APS LAR dated March 21, 2011 (2011 LAR), as supplemented by letter dated August 12, 2011 (ADAMS Accession Nos. ML11103A053 and ML11235A515, respectively). When implemented, TSTF-425 relocated most periodic frequencies of TS surveillances to a licensee-controlled program, the Surveillance Frequency Control Program (SFCP), and provided requirements for the new program in the Administrative Controls section of the TSs. The proposed change in LAR dated September 27, 2013 (2013 LAR) would result in the frequency of all relay testing required by SR 3.3.6.2 to be controlled by the SFCP. The licensee stated that it was an oversight to not include the surveillance frequency of the Note in SR 3.3.6.2 in the SFCP in the 2011 LAR that requested approval of TS revisions that reflected the relocation of certain periodic surveillance frequencies to the SFCP when TSTF-425 was adopted.

In the 2013 LAR, APS states that the change to SR 3.3.6.2 would align with PVNGS Amendment No. 188 that adopted TSTF-425. Under Amendment No. 188, most periodic frequencies of TS surveillances were relocated to the SFCP in the Administrative Controls section of the TSs except (1) Frequencies that reference other approved programs for the specific interval; (2) Frequencies that are purely event-driven; (3) Frequencies that are event-driven, but have a time component for performing the surveillance on a one-time basis once the event occurs; and (4) Frequencies that are related to specific conditions. The test frequency note within SR 3.3.6.2 is not in any of the above categories, thus the surveillance frequency should have been relocated to the licensee-controlled SFCP in Amendment No. 188. Testing

for actuation logic subgroup relays is still required but the frequency is no longer specified in the TSs. Amendment No. 188 authorized APS to use Nuclear Energy Institute (NEI) 04-10, "Risk-Informed Technical Specification Initiative 58, Risk-Informed Method for Control of Surveillance Frequencies," dated July 2006 (ADAMS Accession No. ML062570416) for any changes to surveillance frequencies within the SFCP. According to NEI 04-10, probabilistic risk assessment methods are used, in combination with plant performance data and other considerations, to identify and justify modifications to the surveillance frequencies of technical specification required equipment.

The NRC staff has evaluated the licensee's proposed change which would revise SR 3.3.6.2 to be in accordance with the SFCP for ESFAS Logic subgroup relays exempt from testing during operations. The NRC staff has determined that the controls established by NEI 04-10 have been applied to both the surveillance test frequency for subgroup relays tested during operation and subgroup relays not tested during operations under the SFCP. Also, the NRC staff finds that the licensee would continue to meet the regulatory requirement of 10 CFR 50.36( c)(3), by having surveillance requirements to ensure necessary quality of systems and components are maintained, the plant operation is within safety limits, and that the limiting conditions for operation are met. Therefore, the NRC staff concludes that this change is acceptable.

3.3 Summary and Conclusions The NRC staff has reviewed the licensee's proposed change to reinstate a 4-hour completion time, which was inadvertently omitted in the LAR dated September 17, 2003. The NRC staff considers the change to reinstate a 4-hour completion time to be corrective in nature and is consistent with the safety analysis. Therefore, the NRC staff concludes the change is acceptable.

In addition, the NRC staff has reviewed the licensee's proposed change to move the frequency of the SR 3.3.6.2 Note to the licensee-controlled SFCP for actuation logic subgroup relays exempt from testing during operations. The NRC staff concludes the change would make the frequency of the relays exempt from testing controlled in the same manner as the frequency of SR 3.3.6.2 for testing actuation logic subgroup relays. Therefore, the NRC staff concludes the change is acceptable.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Arizona State official was notified of the proposed issuance of the amendment. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendments change a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendments involve no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The

significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration, and there has been no public comment on such finding published in the Federal Register on February 4, 2014 (79 FR 6640). Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
