Docket Nos. 50-269, -270, -287
Dear Sir:
My letter of November 15, 1976 responded to an August 12, 1976 request for additional information concerning the susceptability of Oconee Nuclear Station operation and equipment to degraded grid voltage conditions.
In the proposed actions section of the report, it was stated that undervoltage relays on the emergency power system would be reset by March 1, 1977 to ensure the minimum voltage required for continuous operation of non-safety and safety-related equipment under any postulated degraded conditions.
It is now anticipated that thi-, action will be completed by April 1, 1977.
Very truly yours,
', h / LJ William O. Parker, Jr. dr /Y
