Power was rapidly reduced manually; however, a pressure imbalance in the Main Condenser caused a secondary plant transient. The reactor was manually scrammed two mintues after the Circulating Water Pump trip. On August 26, the unit was placed on line, but power was limited to less than 504 while waiting for Circulating    Pump  Motor parts.
On August 28, power was reduced and the      unit manually brought off line to repair    an  unisolable drain line off of the 2B Moisture Separator  Reheater. The  reactor remained    critical  while the section of leaking    pipe was  replaced. On  August 29, the unit was placed on  line  and reached  full power  on August  30th.
Average power  for the  month excluding the above power reductions was 964.}}

SUMMARY

OP OPERATING EXPERIENCE DOCKET NO: 50-244 UNIT: R.E. Ginna Nuclear Power Plant DATE: tember 8 1995 COMPLETED BY:

John Walden TELEPHONE: 716 771-3588 MONTH Au ust 1995 On August 25, the "B" Circulating Water Pump tripped due to a bolt failure which affected the pump's motor electrical control circuitry. Power was rapidly reduced manually; however, a pressure imbalance in the Main Condenser caused a secondary plant transient. The reactor was manually scrammed two mintues after the Circulating Water Pump trip. On August 26, the unit was placed on line, but power was limited to less than 504 while waiting for Circulating Pump Motor parts.

On August 28, power was reduced and the unit manually brought off line to repair an unisolable drain line off of the 2B Moisture Separator Reheater. The reactor remained critical while the section of leaking pipe was replaced. On August 29, the unit was placed on line and reached full power on August 30th.

Average power for the month excluding the above power reductions was 964.
