1. . Honthly Report for Draldwood Unit 1

• A. liummDry of OpHAL1DglAptLitnCR On September 1, 1991 a load reduction was taken to clean the condensate / condensate booster pump stralners. Following this maintenence, the unit returned to normal operations until i September 22, 1991 when load was reduced to repair an oil leak i in a feedwater_ pump. Following repairs, the unit operated routinely the remainder of the month.
