SUMMARY

OF CPERATING EXPERIENCE June 1992

'Ihe unit began the month at 100% pow (RSS MWe).

Power was reduced to 98% at 0435 on June 5 due to !mlications hat condenscr cooling v>ater differential temperature was greater than 120F. The unit was returned to 100% power at 0510 after operators determhed that the actual differential temperature war les than 120F.

The unit was manually tripped at 0309 on June 24 due to decreasing vacuum in the Main Condenser.

The cause was a ruptured expansion joint between the turhine and 21 Condenser. The unit was

= cooled down to Mode 5 on June 25 tor repairs.

The expansion joint was replaced but the unit remained in Mode 5 to replace 22 Containment Air Cooler's Imwer cables.
