The momentary contact resulted in the partial loss of the non-safety related annunciator system.

05/04 0749 Commenced RX downpower to 70%

after the Core Operating Limit Supervisory System (COLSS) stopped calculating.

05/04 0819 The determination was made that the Plant Computer System had subsequently degraded to a point that the Emergency Plan was entered and an ALERT declared.

05/04 1021 RX at 70% power.

05/06 2321 The ALERT was terminated and the station exited the Emergency Plan as a

result of the rework that had been completed on the Plant Annunciator System and the Plant Computer System.

The determination was made by senior plant management to shut down the plant to perform additional testing needed to ensure long term reliability of these two systems.
