SUMMARY

OF OPERATING EXPERIENCES Limerick Unit 2 began the month of February at 97% of rated thermal power. On February 2, reactor power was reduced to 86% and a control rod pattem adjustment was made in order to retum to 100% power. On February 3, reactor power was reduced to 71% when Instrument air low pressure to the feedwater heater control valves occurred. Power was retumed to 100% by early moming on February 4 following correction to the instrument air problem. On February 5, reactor power was reduced to 90% to perform a control rod pattem adjustment. On February 13, reactor power was reduced to 95% due to increased offgas hydrogen levels. On February 15, reactor power was reduced to 85% to perform rnain turbine control valve tests and a control rod pattem adjustment.

On February 17, reactor power was reduced to 95% due to reactor feed pump control problems, On Februt y 20, reactor power was reduced to 14% and the main turbine generator taken off line at 1912 hours0.0221 days 0.531 hours 0.00316 weeks 7.27516e-4 months to perform a repalt to e previously identified electro-hydraulle control (EHC) fluid leak at the #2 main turbine control valve servo. Reactor power was maintained at 14% during the repair with steam bypassed to the condenser, Unit 2 main turbine generator was synchronized to the grid at 0134 hours0.00155 days 0.0372 hours 2.215608e-4 weeks 5.0987e-5 months and retumed to 100% reactor power on February 21. On February 22, reactor power was reduced to 95% to perform a control rod pattern adjustmeat. Unit 2 ended the month at 100%

of rated thermal power.

Operational events that occurred during the month of February included:

On February 3, following the removal from service of the '2A' Instrument Air compressor dryer package, the Control Room received several feedwater heater level and Instrument Alt header low pressure alarms. The Auxillary Plant Operator was Instructed to restore the dryer package. Following the restoration of the dryer package, instrument Air header pressure returned to normal. Further investigation determined that the cause of the event was failure of a valve operator at the inlet to the in. service '2B' instrument alt dryer tower, The valve operator was subsequently repaired.

On February 13, reactor power was decreased to approximately 9% of rated thermal power when the offgas system hydrogen concentration levels reachrd 3.6% due to recombiner preheater problems. Following the power reduction, hyr'.rogen concentration levels decreased to 3.2%. Following investigation, induced air in-leskage was increased to dilute the hydrogen concentration. Following the increase in air inleakage, the hydrogen t

concentration levels decreased to approximately 2.2%. Paactor power was subsequently returned to 100% on February 14.

On February 17, the '2C' Reactor Feed Pump minimum flow valve failed open causing reactor power to decrease by 50 MWe, Reactor level decreased to + 27 inches before the

'2A' and '20' RFP's compensated and restored level to + 35 inches. The manual minimum flow isolation valve was closed to prevent flow to the Main Condenser. The valve was found to have failed open due to loss of power to the local flow controller. On February 19, the System Engineers found two defective cards in the controller, The cards were replaced and the valve was verified to operate properly. The manual valve was subsequently reopened.
