OPERATING sum 1ARY - JULY 1981 UNIT I Unit One began the month at 96.7% full power - in a power limited condition due to the downcomer water level of the "A" OTSG. A gradual reduction in the "A" OTSG downcomer water level allowed power to be increased to 99.24% on July 7, 1981. On July 8, 1981, Unit One reactor tripped on high RCS pressure when the "A" MFW pump tripped on low suction pressure. The unit resumed 100% full power operations on July 9, 1981, and continued there until July 15, 1981. On July 15 Unit One was brought to cold shutdown to repair a leaking manway on the primary side of the "A" OTSG. Heatup of Unit One began on July 27, 1981, af ter repair of the "A" OTSG and 100% full power was attained July 29, 1981. Unit One continued to operate at 100% full power through the end of the month.
