20555 Attention: Mr. Darrell G. Eisenhut, Director NRC DOCKETS 50-321, 50-366 OPERATING LICENSES DPR-57, NPF-5 EDWIN I. HATCH NUCLEAR PLANT UNITS 1, 2 ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED EQUIPMENT GENTLEMEN:

As requested by the NRC in Mr. D. Eisenhut's letter dated October 1, 1980, GPC hereby submits information relating to upcoming environmental qualification testing programs for certain saf(ty-related equipment to be installed at Plant Hatch.

The attached table provides a schedule for qualification testing of the Analog Transmitter Trip System (ATTS).

It is anticipated that this system may be integrated into Plant Hatch beginning in spring, 1983.

The ATTS is a General Electric Company (GE) supplied system which GPC has purchased for Plant Hatch, not only to aid in meeting the NRC I&E Bulletin 79-01B requirements, but also to improve the reliability and availability of Plant Hatch generation.

The ATTS is a

solid-state electronic trip system designed to provide stable and accurate monitoring of various process parameters and replaces many existing water level, pressure, and temperature switches with solid-state electronic transmitters and trip relays.

For Plant Hatch, these replac vnents will be associated with equipment which monitor and control various functions in the Emergency Core Cooling and Reactor Protection Systems.

The ATTS is presently being qualified to the requirements of IEEE 344-1975 and IEEE 323-1974 in accordance with the methodology specified in NUREG-0588, for Category 1 equipment.

The testing (seismic and LOCA loads) that is presently necessary, in order to complete the qualification of this system to these requirements, is' presented in the attached table.

The table shows two cabinet qualification programs underway for ATTS.

" Phase 1" is a GPC Plant Hatch specific program while " Phase II" is a GE BWR generic ' program.

In both cases the electronic equipment internal to the cabinet is being tested as a part of this program. As this table indicates, LOCA testing it not a requirement of the qualification program for these cabinets because the cabinets will be located in a " mild" environment.
