20555 NRC DOCKET 50-321 OPERATING LICENSE DPR-57 EDWIN 1. HATCH NUCLEAR PLANT UNIT 1 REVISION TO REQUEST FOR TECHNICAL SPECIFICATION CHANGES TO SUPPORT COMPLETION OF ANALOG TRANSMITTER TRIP SYSTEM INSTALLATION Gentlemen:
By letter dated July 24, 1985 (NED-85-528), Georgia Power Company (GPC) submitted a proposed amendment to the Plant Hatch Unit 1 Technical Specifications to support plant modifications associateo with installation of a
General Electric Company (GE)
Analog Transmitter Trip System (ATTS).
Following discussions with members of the NRC staff regarding this submittal, GPC has determined that a withdrawal of two of the proposed Technical Specifications limits from consideration is appropriate pending further analysis.
Proposed changes on pages 3.2-11 and 3.2-14 in the " Proposed Technical Specifications Revisions" Section of the enclosure to NED-85-528 (item 3 on each page), specify allowable Trip Settings for-the Reactor Vessel Steam Dome Pressure Low Permissive to open injection valves for the LPCI and Core Spray Systems.
GPC has determined that the 500 psig ' upper limit on those allowable Trip Setpoints, which is currently in Technical Specifications (as a footnote on each of the referenced pages), should be retained to provide adequate over-pressurization protection for the low pressure Emergency Core Cooling Systems (ECCS) at Plant Hatch.
However, GPC is pursuing a thorough reanalysis to support a decrease in the lower limits for these permissives.

i, GPC requests that the NRC exclude the ~ above specified proposed
}
Technical Specification limit changes from the scope of review for i
NED-85-528, and that any amendments issued as a result retain the 4
current values for those items.
To. clarify this request the two
(
l subject proposed Technical Specifications pages, revised to account t
i for this latest determination, are attached for your information and use.
f j
GPC intends to submit new proposed revisions for the above i
referenced limits, following completion and review of the above referenced reanalysis.
In the interim, NRC approval of the changes proposed by NED-85-528, as revised by this submittal, would permit acceptable restart and operation of Plant Hatch Unit I using ATTS.
I Since this submittal only retracts certain revisions previously l
proposed by NED-85-528, which are not functionally. related to any l
other Technical Specifications changes presented in that letter, the safety evaluation (required by 10 CFR 50.59) and the significant l
hazards review (required by 10 CFR 50.92) for the original submittal are unaffected.
4 Very truly yours, f r~ x i
