NARRATIVE

SUMMARY

OF OPERATING EXPERIENCES JUNE 1981 UNIT 2 OPERATIONS The unit remained shutdown for repairs to d ao "B" Recirculation Pump / Motor and the HPSV piping downstnam of the 113 valve. While the unit was being returned to service on June 10, the 2A main transformer experienced an internal fault prior to attaining full operating voltage. Repairs were nade to the transformer

, and the unit was placed in service on June 21. On June 22, tho unit tripped on low reactor water level rssulting from loss of feedwater.

The loss of feedwater was due to the tripping of two condensato pumps when the number 213kv bus tripped due to water leakage into the 2Gk breaker grounding the bus. The unit was returned to service on June 23 The unit was removed from service within a few minutes in an effort to maintain condenser vacuum following high hydrogen concentration trips of the Recombiner mechanical compressors. Over the next few days, the unit was cycled on and off a number of times for the same reason. .

It was determined that the high hydrogen concentrations at the outlet of the recombiner were the result of oil leakage into the con 6cnsate from the water seal drain system of the "A" Reactor Feed Pump.

The unit was returned to service June 25 with major load drops required periodically over the next several days to maintain condenser vacuum each time the Recombiner mechanical compressors tripped on high hydrogen concentration. The situation continued to improve as the oil was removed by special resin used in the condensate demineralizers.

UNIT 3 OPERATIONS The unit remains shutdown to accommodate refueling, modifications and maintenance work. The Suppression Pool modifications are complete with sand blasting and recoating remaining. The feedwater nozzle machining and sparger replacement is complete.

The in-drywell Oore Spray piping replacement has been completed and replacement of the in-drywell Reactor Vater Cleanup i piping is in progress. Repair of the 2B Recirculation pump motor continues.
