Dear Mr. Beckham:
RPrevatte 00 Our generic letter of August 8,1979 ehkhek Adequacy of Station Electric Distribution Systems Voltages, described an event, at a nuclear pPwer generating station, that caused concern about the conformance, at all nuclear plants, to our General Design Criterion 17, Electric Power Systems. By letters dated December 7,1979, April 28 and October 9,1980 and January 12, 1982, yourresponded to our letter of August 8,1979.
lle have completed our review of your analyses and design changes, as submitted in the above mentioned correspondence, and conclude, based on the enclosed Safety Evaluation, that the Hatch Plant Units 1 and 2, electric dis $ribution systen voltages comply with G0C 17 and therefore, we find the design to be acceptable.
Sincerely,
JonE. srctze,
John F. Stolz, Chief Operating Reactors Branch #4 Division of Licensing
