- 1. 0 INTRODUCTION By letter dated November 20,
- 1992, as supplemented by letters dated October 22,
- 1993, and November 30, 1994, Arizona Public Service Company (APS or the l,icensee) submitted a request for changes to the Technical Specifications (TS) for the Palo Verde Nuclear Generating Station, Units 1, 2, and 3 (Appendix A to Facility Operating License Nos.
NPF-41, NPF-51, and NPF-74, respectively).
The Arizona Public Service Company submitted this request on behalf of itself, the Salt River Project Agricultural Improvement and Power District, Southern California Edison
- Company, El Paso Electric Company, Public Service Company of New Mexico, Los Angeles Department of Water and
- Power, and Southern California Public Power Authority.
The proposed changes would revise TS 3.2. 1 and 3.2.4 and the associated Bases for the Palo Verde Nuclear Generating Station (PVNGS), Units 1, 2, and 3.
These amendments would increase the time limit that the core operating limit supervisory system (COLSS) may be out of service before the action requirements based on the more restrictive core protection calculator (CPC) limits apply.
The proposed amendments would also differentiate the actions required for operating with and without the COLSS.
The October 22,
- 1993, and November 30, 1994, letters responded to the staff's March 16, 1993, request for additional information.
These supplemental letters provided certain revised TS pages for clarification purposes and did not change the original no significant hazards determination.
- 2. 0 DISCUSSION The COLSS and the CPCs provide two different methods of monitoring the core power distribution.
The COLSS and CPCs that monitor the core power distribution are.capable of verifying that the departure from nucleate boiling ratio (DNBR) and the linear heat r ate (LHR) do not exceed their limits.

that the proposed changes to TS 3.2.1 and 3.2.4 and the associated Bases are acceptable.
- 4. 0 STATE CONSULTATION In accordance with the Commission's regulations, the Arizona State official was notified of the proposed issuance of the amendments.
The State official had no comments.
- 5. 0 ENVIRONMENTAL CONSIDERATION The amendments change a requirement with respect to the installation or use of a faci.lity component located within the restricted area as defined in 10 CFR Part 20 and change surveillance requirements.
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 incr ease in individual or cumulative occupational radiation exposure.
The Commission has previously issued a
proposed finding that the amendments involve no significant hazards considera-
- tion, and there has been no public comment on such finding (58 FR 591).
Accordingly, the amendments meet the eligibilitycriteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.
- 6. 0 CONCLUSION The Commission has concluded, based on the considerations discussed
- above, that (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed
- manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and'ecurity or to the health and safety of the public.
