After completion of turbine balance, plant startup was further delayed due to containment isolation valve problems. After valves were repaired, the plant was returned to service.

9344 2/06/93 F 32.42 A 93~ CB Pumpxx Reactor was manually scrammed when reactor recirc pump failed to transfer to 60 HZ operation due to false signal (noise) in the pump control circuitry.

93%5 2/10/93 F 160.38 A 93-007 CH Pumpxx Reactor automatically scrammed on low level due to loss of reactor feedwater pump. The cause of failure was an electric coil in the feed pump governor control circuitry. After repairs were performed, startup activities were placed on administrative hold while an assessment was performed on recent plant problems. After compl of assessment, the plant was returned to service.

INSTRUCTIONS ON THIS FORM, LIST THE AVERAGE DAILYUNIT POWER LEVEL IN MWe-NET FOR EACH DAY IN THE REPORTING MONTH. COMPUTE TO THE NEAREST WHOLE MEGAWATT.

THESE FIGURES WILLBE USED TO PLOT A GRAPH FOR EACH REPORTING MONTH. NOTE THAT WHEN MAXIMUMDEPENDABLE CAPACITYIS USED FOR THE NET ELECTRICALRATING OF THE UNIT, THRE MAY BE OCCASIONS WHEN THE DAILY AVERAGE POWER LEVEL EXCEEDS THE 100Fo LINE (OR THE RESTRICTED POWER LEVEL LINE). IN SUCH CASES, THE AVERAGE DAILYUNIT POWER OUTPUT SHEET

, SHOULD BE FOOTNOTED TO EXPLAINTHE APPARENT ANOMALY.
