HATCH NUCLEAR PLANT UNIT 2 REVISION TO RECIRCULATION PIPING REPLACINFNT REPORT TO NRC Gentlemen:

By letter dated November 7, 1983, Georgia Power Company (GPC) transmitted a report to NRC concerning the recirculation piping replacement at Plant Hatch Unit 2. "Ihat report has been updated to clarify and amplify the information provided. Eight (8) copies of the revised report are enclosed. The ' revisions consist of certain editorial changes and the following substantive changes:

1. De role of the Georgia Power Company Quality Assurance Department is described (subsection 2.6.1 and section 16.0).

2. The description of the seismic analysis has been rewritten (subsection 5.3.3).

3. We description of the pipe whip restraint design has been rewritten (subsection 5.3.5).

4. A description of the analysis for LOCA effects has been added (subsection 5.3.6).

Our November 7, 1983, letter indicated that proposed changes to the plant's Technical Specifications to accommodate the piping replacement had been sQbmitted by our October 20, 1983 letter. Review by NRC determined that the proposed changes were unnecessary based on its interpretation of Technical Specifications with regard to the applicability of limiting conditions for operation while all fuel is removed from the reactor vessel.

Consequently, GPC withdrew the proposed Technical Specification changes by letter dated November 16, 1983. \
