SUMMARY

OF OPERATING EXPERIENCE FOR SEPTEMBER 1990 Power was maintained at 80% until September 15 when at 0816 the reactor power was decreased at 12% per hour to shutdown for a scheduled 150 day outage to refuel the reactor and replace the steam generators.

The plant was offline by 1404 and the reactor was subcritical at 1423.
