Joseph M. Farley Nuclear Plant - Unit 2 Supplemental Response to I.E.Bulletin 79-14

Dear Mr. O'Reilly:

In our revised response to I.E.Bulletin 79-14 dated August 15, 1980, Mabama Power Company outlined the types of infonnation used as input to the final seismic analyses of the as-built configuration of piping systems.

In addition to this information, it has also been verified that correct valve weights and valve centers of gravity have been used in the analyses and that the seismic response spectra curves used in the analyses envelope OBE and SSE conditions.

Very truly yours, c-C/
