Georgia Power Company (GPC) would like to amend its submittal of March

( 30, 1983, in order to respond to your question concerning the extension of

MAPLHGR limits for Hatch. We have evaluated the results of our ECCS analyses for all fuel types which may be inserted in Hatch-2, and we have concluded that the results conform to the criteria specified in

reference 1. With the exception of three exposure points, the peak clad temperatures for Hatch-2 fuel do not exceed those assumed in GE's BWR-4 limiting plant analysis. In these three cases the peak clad temperature for

! the Hatch-2 fuel is below the 200 margin which is considered a significant l deviation by 10 CFR 50 Appendix K (Section II.l.b). We conclude,therefore, l

that our ECCS analysis results justify the operation of all Hatch-2 fuel l types at exposures greater than 30000 mwd /st.

l l

Sincerely yours,
