NHC Monthly Operations Summa 7 l'rath Hottom Atomic powcr Station Augu611991 MU Unit 2 tiegan the month at nominal 1(KK5 powet er.d acmained at thet level until August 3 when power was reduced to approximatcly.VO MWe for replacement of the '11' recite motor litushes. An automatic scram occurrcd on August 5. The proximate events leading to the scram were a high level signal for the 'D' moisture separator drain tank, leading to a turbine control valve fast closure. Conditions leading to the scram were corrected and the generator was synchronited to the grid on August 7.

The unit returned to norninal 1(0% power by August 8 and maintained that gwer level until August 27. On that day, the !!2 diesel generator experie nced a proldem with a field generator ground, and was declared inogerable.

Since the l!3 dicsci was already out of senice for in 41ntenance,luith units began a required shutdown. The !!2 diesel ground was found and repaired, and the diesel was declared operable on August 23. power was returned to Im% the same day and remained at that level for the rest of the month.

MU Tie unit began the month in the coastdown maic at slightly reduced power, and maintained power levels between nominal 99% and W.1 until At c t 24, when power was reduced slightly for repairs to the 'C' Ri~p os control linkage. Repairs were completeu the same day, and the unit returned to peak coastdown power. The unit entered a controlled shutdown related to the II2 dicscl, as discussed aloc, late on August 27, and returned to maximum coas.tdown power late on August 28.

The unit ended the month at nominal %% power, with prepara' ions for the reluct outage in progress.
