SUMMARY
OF OPERATING EXPERIENCE FOR MAY, 1989 Palisades began the month of May with power being maintained at 80%.
On May 1, at approximately 0700, a plant upset occurred while removing the dilution water pump P40B from service.
Air leakage into the East Main Condenser Waterbox re-duced circulating water flow through the condenser, resulting in a decreasing condenser vacuum.
An emergency power reduction (from 80% to 35% in 7 minutes) using control rods was utilized to spare the plant from a low vacuum trip.
An increase in power began at 0930 with 80% power being reached at 1945.
Reactor power was then maintained at 80% for the remainder of the month.
