3 oO PURPOSE:

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. ~ /R2 5 0 RELATED SYSTEM STATUS:

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.

The following personnel were directly involved with the event and may be able to supplement the information in this report if clarification is needed.

Bo For complicated transients, or situations where the Sequence of Events Recorder fails, attach statements from personnel involved with the trip concerning the events that preceded and followed the trip. Each individual should submit a statement concerning the way they remember the event.

If handwritten statements are prepared, include the plant conditions prior to the trip, your indications that a problem existed, vour action as a result of those indications, noted equipment malfunctions or inadequacies, any unusual plant conditions or annunciators, and any identified procedure deficiencies. Also, include any information you consider important for review of this unscheduled reactor trip and any actions necessary to prevent recurrence. (Use additional sheet if necessary)

PART 12: RESTART AUTHORIZATION:

If theicause of the plant trip cannot be determined by the Nuclear Plant Supervisor the unit will not be'eturned to power until an Independent Review of the event has been performed by the Faci'lity Review Group.

A. Based upon the information available and this review, the cause of the Reactor Trip has been identified, no unsafe conditions exist. The Plant Manager or his designee authorizes restart.
