Before use, verify informetion with e controlled document.Approved by A 3 oO PURPOSE: Plant Manager Co-2t'9%-This procedure will identify any abnormal circumstances associated with a plant trip by evaluating plant conditions immediately prior to and immediately after the trip.4+0 LIMITS AND PRECAUTIONS:

4.1 It is important that the First Out annunciator reset, RPS Trip Unit indicating lights, and any electrical system protection relay flags not be reset until their status is noted in this Post Trip Review Check List.This data is particularly important if the plant, Sequence of Events Recorder has malfunctioned.

8.1 This procedure will be performed following any unplanned reactor trip after plant conditions have been stabilized.

The procedure need not be performed following a planned shutdown.8.2 Input from all plant personnel is vital to the correct identification of the cause of the plant trip and of any related malfunctions.

8.3 All data pertinent to the plant trip should be collected and kept with this procedure.

If recorder charts are used in this evaluation, a clear copy should be made, and the chart returned to its recorder.8.4 All blanks on the"POST-TRIP REVIEW CHECK LIST" should be filled in, use N/A where not applicable.
