August 15, 1985 NARRATIVE SUMMA".Y Month: July 1985 Catawba-Unit 1 began the month at 100%. On July 4, the unit reduced to 85%

power to repair a heater drain pump steam leak. The unit returned to 100%

on July 6.

On July 10 the unit tripped when a channel of nuclear instrumentation

.was inadvertently isolated during a test.

The unit returned to service on July 12.

On July 19, the unit reduced power to 89% for testing and returned to 100% on July 23.

The unit operated at 100% until a condenser tube leak forced it off-line on July 28.

The unit returned to service on July 30, but was forced back off line by chemistry problems. The unit remained off line through July 31.
