NOUE DECLARED DUE TO REDUCED PLANT SERVICE WATER FLOW
Licensee reported that service water pump intake bay level decreased requiring the shutdown of one dilution water pump to increase bay level to normal. Flow was reduced on the operating dilution water pump by throttling the discharge flow to maintain bay level at the normal operating level. The cause of the reduced service water bay level is being investigated. The licensee has notified the State of Michigan and VanBuren county. The licensee will contact the NRC Resident Inspector.
Notified FEMA of this event
* * * UPDATE AT 0418 EST ON 2/16/03 BY GERRY WAIG * * *

* * * UPDATE AT 1600 EST ON 2/16/03 BY HOWIE CROUCH * * *
Divers are at Palisades and preparing to inspect (most likely tomorrow). The plant is stable and the bay level is stable. The plant continues in the Unusual Event. Exit criteria will be root cause discovery. It was noted that South Haven municipal water (near Palisades) was experiencing like symptoms.
* * * UPDATE AT 1301 EST ON 2/19/03 BY HOWIE CROUCH * * *
The licensee has terminated the NOUE declared on 2/16/03. The licensee has restored full capability to provide make-up water to the plant's service water intake (ultimate heat sink). The NRC Resident Inspector has been notified by the licensee. Headquarters Operations Officer notified R3DO (Miller), NRR EO (Zwolinski), FEMA and DIRO (Hiland).
