The cause of contact failure was With D/G A a buildup of insulating layer of silver oxide or Out of copper oxide on surface of movable contact Service for (gold plated). It was determined that on Diesel Maint, startup this buildup occurs during contact arcing D/G B failed when a downstream relay is de-energized its daily test Immediate corrective action was to replace the relay. Long-term corrective actions are being determined.

SUMMARY

An Unusual Event was declared February 26 at 0026, based on EPIP-AD-02 (Emergency Class Determination), Chart E (Loss of Power), with indication being RCS above Cold Shutdown and both D/Gs unavailable.

Power reduction to Hot Standby, per Technical Specification 3.7.b.2, began at 0107. The Unusual Event was terminated at 0656 with the Reactor in Operating Mode at 9% power.

Following repairs to Diesel Generator B and its return to service, load increase to 35% power was initiated at 0950. 100% power was reached on February 28 at 0645.

The unit continues to operate at 100% power.
