SUMMARY

OF OPERATING EXPERIENCE DATE 2 2 TELEPHONE 763/295-1006 MONTH JAN 01-01-02 Power operation.

to 01-11-02 01-11-02 Power reduction to 65% to perform Maximum Core Flow/Prompt to Flow Control Line Determination test, investigate Main 01-12-02 Condenser air in-leakage and to adjust control rods and precondition fuel.

01-12-02 Power operation.

to 01-21-02 01-21-02 Reactor shutdown following scram. Failure of the Pressure to Control System caused a load reject signal. The return to 01-27-02 power was delayed by the failure of MO-2076, RCIC Steam Line Isolation Outboard, during startup, and subsequent repair.

01-27-02 Reduced power operations during startup for scram recovery.

to 01-29-02 01-29-02 Power operation.

to 01-31-02 Note: Power operation defined as essentially 100% of rated power except for weekend load drops for specified surveillance testing.
