SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. 83 TO FACILITY OPERATING LICENSE NO. DPR-72 FLORIDA POWER CORPORATION, ET AL.

CRYSTAL RIVER UNIT NO. 3 NUCLEAR GENERATING PLANT DOCKET NO. 50-302 1.0 Introduction By letter dated July 25, 1984, Florida Power Corporation (FPC, the licensee) made application to amend the Technical Specifications (TSs) for Crystal River Unit 3 (CR-3) to delete the surveillance regairement that the operability of the sump pumps in the tunnel containing the DC control supply to the 230kv switchgear be verified at least once per seven days. This amendment would delete the surveillance requirement of TS 4.8.1.1.1.a.2.

2.0 Discussion and Evaluation To comply with TS 3.8.1.1, the sump pumps in the tunnel containing the DC control feeds to the 230kv switchgear must be operable. Within the tunnel there are four sump pumps, two on either side of a dividing wall. Two of these pumps are considered to be backups. One set of the DC control and protective circuits is located in conduit and trays. A redundant set of DC control and protective circuits, with cable manufactured by Kerite, is contained in separate conduit. The licensee provided Kerite's information to verify that the Kerite cables are not adversely affected by rain or salt water submersion. Also, unavailability of DC supply to the 230kv switchgear due to any faults or other reasons is annunciated in the control room.

Therefore, the licensee stated that " weekly verification of pump operability and running the Emergency Diesel Generators if the pumps are inoperable are not necessary to assure plant safety." Having reviewed the information and justification provided by the licensee, the NRC staff agrees that surveillance of the sump pumps as a TS requirement is unnecessary for the safety of the plant. Therefore, we find that the proposed change to the TSs to delete Surveillance Requirement 4.8.1.1.1.a.2 "That the sump pumps in the tunnel containing the DC control feeds to the 230kV switchgear are OPERABLE" is acceptable.

3.0 Environmental Consideration This amendment deletes a surveillance requirement. We have determined that the amendment involves 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 Comission has previously 8510150319 850930 g2 DR ADOCK O

issued a proposed finding that this amendment involves no significant hazaros consideration and there has been no public comment on such finding.

Accordingly, this amendment meets the eligibility criteria 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 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 Commission's regulations 4

and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
