SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION

_ SUPPORTING AMENDMENT NO. 98 TO FACILITY OPERATING LICENSE NO. DPR-46 NEBRASKA PUBLIC POWER DISTRICT COOPER NUCLEAR STATION DOCKET N0. 50-298

1.0 INTRODUCTION

By letters dated May 31, 1985 and August 21, 1985 (Change No. 22) the Nebraska Public Power District (the licensee) requested an amendment to Facility Operating License No. DPR-46 for the Cooper Nuclear Station.

The proposed amendment would change the Technical Specifications (TS), to incorporate Limiting Conditions for Operating (LCO), Surveillance Requirements (SR), and Bases for the station service water pump -room Halon fire suppression system and fire detectors.

2.0 _ DISCUSSION AND EVALUATION By letter dated June 28, 1982, the licensee requested an exemption from the requirements of Appendix R to 10 CFR 50 for the service water intake structure due to inadequate separation between service water pumps. As part of the exemption request, the licensee proposed to install an automatic fire suppression system and a detection system. By letter dated September 21, 1983, we granted the exemption. The proposed amendment would add LC0's and SR's for the Halon system and the fire detectors to the TS.

We have reviewed the proposed TS for conformance to the staff's guidance i of NUREG-0123 (BWR Standard Technical Specifications). The additional I fire detectors would be included under the existing LC0's and SR's )

applicable to the other detectors. The licensee has not included a SR to periodically verify that each valve in the Halon flow path is in its correct position because the system includes only check valves and explosivc-actuated valves. Due to restricted quarters the licensee has also not included a SR to periodically weigh the Halon tanks to verify Halon content. As an alternative, the licensee proposes to verify Halon content by use of a dipstick for each tank. The licensee has also not included a " puff test" SR to periodically verify that nozzles are unobstructed. In lieu of a puff test a visual and tactile inspection will be performed. This eliminates the need to break the mechanical integrity of the system for testing. These features are acceptable to the staff. The proposed amendent is otherwise consistent with the Standard TS and is acceptable.

3.0 ENVIRONMENTAL CONSIDERATION

S This amendment changes a requirement with respect to installation or use of a tacility component located within the restricted area as defined in 10 CFR Part 20, and changes surveillance requirements. The staft nas determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents tnat may be released oftsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Comission has previously issued a proposed finding that this amendment involves no significant hazards consideration and there has been no public comment on such finding. Accordingly, this amendment meets the eligibility criteria for categorical exclusion set fourth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b) no environmental impact statement or environtrental assessment need be prepared in connection with the issuance of this amendment. ,

4.0 CONCLUSION

We have 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, and (2) such activities will be conducted in compliance with the Comission's regulations, and the issuance of this amendmer.t will not be inimical to the common defense and security or to the health and safety of the l public.
