DATE TYPE HOURS REASON METHOD LER NO SYSTEM COMPONENT CAUSE & CORRECTIVE ACTION TO PREVENT RECURRE 91-09P 12/17/91 F 0 A 5 A power reduction to 63% thermal power was necessitated by high and rising conductivity of the reactor coolant. After one circulating water pump was removed from service, the conductivity returned to normal and the plant was returned to full power.

91-10 12/20/91 F 132.2 A HC HTEXCH The plant was shutdown because of high and rising conductivity of the reactor coolant. A condenser tube leak was repaired and other minor maintenance was performed in drywell prior to returning plant to service.

SUMMARY

WNP-2 incurred one forced outage and one power reduction in December as described above.
