WASHING TON. D. C, 20555 m,,,,,s SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. 53 TO FACILITY OPERATING LICENSE NO. NPF-4 VIRGINIA ELECTRIC AND POWER COMPANY AND OLD DOMINION ELECTRIC COOPERATIVE NORTH ANNA POWER STATION. UNIT NO. 1 DOCKET NO. 50-338 Introduction By letter dated November 15, 1983, the Virginia Electric and Power Company (the licensee) requested an amendment, in the form of changes to the Tech-(
nical Specifications (TS), to Operating License No. NPF-4 for the North Anna Power Station Unit No. 1 (NA-1).
Specifically, the proposed change would delete the requirement to perform surveillance in Mode 4 (Hot Shutdown) for the Auxiliary Feedwater Pump Actuation Signals (AFPAS) from Steam Generator Water Level (SGWL)-Low Low and Station Blackout (SB).
The proposed change would provide consistency within the body of the NA-1 TS and also the NA-2 TS.
Our discussion and evaluation of the proposed change is provided below.
Discussion:
Presently, the NA-1 TS Table 3.3-3 requires that operability be verified by surveillance in Mode 1 (Power Operation), Mede 2 (Startup), and Mode 3 (Hot standby) for AFPAS from SGWL Low-Low and SB. However, Table 4.3.2 of the NA-1 TS requires that surveillance testing be performed for the AFPAS frca SGWL Low-Lcw and SB not only in Modes 1, 2, and 3 but also Mode 4.
There-l fore, an inconsistency presently exists between the NA-1&2 TS Tables 3.3-3 l
and 4.3-2.
In addition, the NA-2 TS require that surveillance of these actuation signals be perforned in Modes 1, 2 and 3 only.
Finally, as stated in NUREG-0452, Revision 4, Standard Technical Specifications for Westinghouse Pressurized Water Reactors, surveillance is required in Modes 1, 2 and 3 for these actuation signals.
Therefore, the proposed change would delete the requirement to perform surveil-lance of the above mentioned actuation signals from the NA-1 TS Table 4.3.2 in Mode 4 only.

, Evaluation Eliminating the required surveillance of the AFPAS from SGWL Low-Low and SB in Mode 4 from the NA TS Table 4.3.2 not only provides consistency with NA-1 Table 3.3-3, but also provides consistency with the approved NA-2 TS.
In addition, the proposed change is in conformance with the NRC approved Westinghouse Standard Technical Specifications which are appropriately applied to NA-1.
Therefore, based on the above, we find the proposed change to be acceptable.
Environmental Consideration We have determined that the amendment is administrative in nature and does not authorize a change in effluent types or total amounts nor an increase in power level and will not result in any significant environmental impact. Having made this determination, we have further concluded that the amendment involves an action which is insignificant from the standpoint of environmental impact and, pursuant to 10 CFR g51.5(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) 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 this amendment will not be inimical to the conmon defense and security or to the health and safety of the public.
