UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 SAFETY EVALUATION. BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. 135 TO FACILITY OPERATING LICENSE NO. DPR-38 AMENDMENT NO.135 TO FACILITY OPERATING LICENSE NO. DPR-47 AMENDMENT NO.132 TO FACILITY OPERATING LICENSE NO. DPR-55 DUKE POWER COMPANY OCONEE NUCLEAR STATION, UNITS NOS. 1, 2, AND 3 DOCKETS NOS. 50-269, 50-270 AND 50-287 1.0 Introduction By letter dated August 8, 1984, Duke Power Company (the licensee) proposed changes to the Technical Specifications (TSs) of Facility Operating Licenses Nos. DPR-38, DPR-47, and DPR-55 for the Oconee Nuclear Station, Unit Nos. 1, 2 and 3. These amendments would consist of changes to the Station's common TSs.
The proposed amendments would revise TS 4.4.1.5.2(a) to change the air lock testing frequency from quarterly to semiannually in conformance with Appendix J, "Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors" to 10 CFR Part 50.
2.0 Evaluation The containment air locks (i.e. Personnel Air Lock and Emergency Air Lock) are utilized during periods of time when containment integrity is required and when the reactor is shutdown. The air locks are tested periodically to verify the integrity of the door seals and thereby, the integrity of the containment.
10 _CFR Part 50., Appendix J., and the Surveillance Requirements (4.6.1.3(b))
of NUREG-0103, Revision 4, "Standard Technical Specifications for Babcock and Wilcox Pressurized Water Reactors" address the requirements for testina the air locks. Based on these requirements, the air locks shall be tested prior to initial fuel loading and at six-month intervals thereafter at an internal pressure not less than Pa.
The frequency of air lock tests as required by the present Oconee TS 4.4.1.5.2(a) is based on three-month intervals.
A change of the air lock testing frequency from quarterly to semiannually conforms to 10 CFR Part 50, Appendix J, regulations. Therefore, we find acceptable the proposed changes to TS 4.4.1.5.2(a).

-2 3.0 Environmental Consideration
- These amendments involve a change in an inspection or surveillance requirement.
We have 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 Commission has previously issued a proposed finding that these amendments involve no significant hazards consideration'and there has been no public comment on such finding.
Accordingly, these amendments meet 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 these amendments.
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 and the issuance of these amendments will not be inimical to the common defense and security or to the health and safety of the public.
