4.....j SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO.101 TO PROVISIONAL OPERATING LICENSE NO. DPR-16 CPU NUCLEAR CO@0 RATION AND JEPSEY CENTRAL PAWER & LIGHT COMPANY OYSTEP CREEK NUCLEAR GENERATING STATION DOCKET NO. 50-219 1.0 INTR 0nilCTION By letter dated January 28, 1986, GPU Nuclear (the licensee) requested an amendment to Provisional Operating License No. DPR-16 for the Oyster Creek Nuclear Generatiro Station (Oyster Creek 1.
This amendment authorizes a chance to the Appendix A Tedhnical Specifications (TS) surveillance requirements on the Fire Pump Diesel 24-volt battery bank in Section 4.12, Fire Protection. Tnis change would allow the licensee to use a two I?-volt battery cell configuration in addition to the existing twelve 2-volt cell confiauration for the 24-volt DC diesel fire pump battery system (DFPBS).
This change would revise the surveillance requirements on the cell voltace to be areater than or equal to either 2 volts or 12 volts based on tha cell configuration.
2.0 OISCUSSION AND EVAlllATION The licensee has proposed Technical Soecification Change Request (TSCR1 138 to orovide the option of using a two 12-volt battery cell configuration--six 2-volt cells with the intercell connaction-inaccessible for surveillance--
in addition to the existing twelve 2-volt cell confiqJration with the 2-volt intercell connection accessible for surveillance.
Either of these cell configurations would provide the 2d volts needed for the 24-volt DC DFPRS.
The DFPRS performance will not be affected by this change. The overall voltace and capacity of the DFPRS will not be chanced. The only change is to allow the DFPBS to be either (11 twelve 2-volt cells with the intercell connection accessible for surveillance being the 2-volt cell or (2) two 12-volt cells with the intercell connection accessible for surveillance beina the 12-volt cell. The 12-volt cell is composed t>f six 2-volt cells but the intercell connections are not accessible for surveillance. This TSCR would not channe the number of 2-volt cells in the DFPBS but it would charge the number of cells reauired to be accessible for surveillance.
It would not chance the overall voltage and capacity of the DFPBS and would not affect the function of the DFPBS. This TSCR would not change the method, frequency or the reliability of the surveillance on the DFPBS.
Therefore, based on the above, the staff concludes that proposed TSCR 138 is acceptable.

3.0 ENVIRONMENTAL CONSIDERATION
This amendment involves a chance to a requirement with respect to the installation or use of a facilitv component located within the restricted area as defined in 10 CFR Part 20 and a change to the surveillance require nents. The staff has determined that the amendment involves no significant increase in the amounts, and no significant chance 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 Commission has previously issued a proposed finding that this amendment involves no significant hazards consideration and there has been no public comment on such findino. 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 nor environmental assessment need be prepared in connection with the issuance of this amendment.
4.0 CONCLUSION
The staff 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, and (21 such activities will be conducted in compliance with the Commission's regulations and the issuance of this amendment will not be inimical to the connon defense and security nor to the health and safety of the public.
