20555 NRC DOCKETS 50-321, 50-366 OPERATING LICENSES DPR-57, NPF-5 EDWIN I. HATCH NUCLEAR PLANT UNITS 1, 2 ADDITIONAL INFORMATION - ESF RESET Gentlemen:
In a telephone conversation with Mr. Dave Verrelli and other members of your staff and your consultants, Georgia Power Company was asked to confirm certain details of our response to I&E Bulletin 80-06, having to do with ESF Reset controls.
Specifically, we were asked to confirm the following:
1.
That the terminology " essential safety systems" as used in our June 12, 1980, response is identical in meaning to your terminology
" systems serving safety-related functions" as used in the bulletin; 2.
That the schedule for completion of the remaining tests is upon completion of each units' respective refueling outage in 1981; and 3.
That the tests associated with the Technical Specification sections listed in the tables provided in our June 12, 1980, response actually test the reset function.
Georgia Power Company has confirmed that the terminology differences in item 1 are just that. The functional meaning of the words is the same as stated in the bulletin.
Although many of the tests listed in item 2 have a nominal 18-month schedule, it is our practice to perform these logic system functional tests during refueling outages to preclude potential undesirable impacts on plant operation. Therefore, all tests identified by the tables submitted will have been completed by the end of the units' refueling g/
outages. The expected completion dates are February,1981 for Vi,it 2 3
and June, 1981 for Unit 1.

20555 January 26, 1981 Page Two The definitions section of the Plant Hatch Technical Specifications defines " Logic System Functional Test" as a test of all relays and -
contacts of a logic circuit, from sensor-to activated device, to ensure that components are operable per design requirements. The tables supplied by our June 12, 1980, response refer to sections of the Techni-cal Specifications which require periodic surveillance, including logic system functional testing. The system logic, including reset logic, 'is j
required to be tested by Technical Specifications.
Very truly yours.
