g SAFETY E & UATION 6Y THE OFFICE OF NUCLEAR RE CTOR REGULATION RELATED TO AMENDMENT NO. 1 TO LICENSE NPF-9 DUKE POWER COMPANY Introduction By letter dated June 17, 1981 the licensee requested certain revisions to the McGuire Nuclear Station Unit 1 Technical Specifications, Appendix A, to License NPF-9. These revisions are:

1.

Revisicn to a diesel generator testing requirments.

2.

Correction to listing of fire detection instrumentation.

The McGuire Unit 1 Technical Specifications were issued on June 12, 1981 as an integral part of the facility operating license and are standard Westinghouse-PWR technical specifications reflecting elant specific design.

Evaluation The McGuire Nuclear Station utilizes the standard Westinghouse-PWR technical specifications and as such have been developed to reflect the McGuire design features.

With respect to item (1), the requirement (T.S.4.8.1.1.2.d.8) to perform a test loading of the diesel generator with design accident loads within 5 minutes after conpletion of a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> test run is a requirement reflecting the staff position regarding diesel generator testing of Regulatory Guide 1.108, " Periodic Testing of Diesel Generator Units as Onsite Electric Power Systems at Nuclear Pcwer Plants". The diesel generator should be so tested during the plant prepera-tional test program and at least once every 18 months. A successful sest loading of both McGuire Unit 1 diesel generators with accident loads was performed durir.g preoperational testing. The technical specification requirement has been revised to reflect the staff testing requirements.

Item (2) relates to fire detection instruments that are required to be operable in each fire zone. The number and location cf smoke detectors and fixed temper-ature/ rate of rise detectors is governed by criteria and requirements of National Fire Protection Association Code 72E-1974. Or.ly one detector is required for each unobstructed fire zone. Additional detectors have been added to compensate for obstructions caused by the amount of cacia located in each fire zone. We conclude that the proposed revision is in compliance with the foregoing and is acceptable.

2-Entir:nm:ntal C nsideration We have determined that the amendment coes not authorize a change in efficent types or total amounts nor an increase in power level and will not result in any significant environmental impact. llaving mada this determination, we h:te further concluded that the amendnent involves an action which is insignificant from the standpoint of environmental impact and, pursuant to 10 CFR Section 51.5(d)(4), that an environmental' impact statement or negative declaration and environmental impact appraisal need not be prepared in connection with the issuance of this amendment.

Conclusion We have concluded, based on the considerations discussed above, that: (1) because tt+e amendment does not involve a significant increase in the probability or con-sequences of accidents previously considered and does not involve a significant decrease in a safety margin, the amendment does not involve a significant hazards consideration, (2) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (3) such activities will be conducted in conpliance with the Commission's regulations 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.
