Docket No. 50-352 Attachment to Monthly Operating Report for February 1990 Limerick Generating Station Unit 1 February 1 through February 28, 1990 I.

Narrative Summary of Operatina Erneriences Limerick Unit 1 began the month of February at a nominal 100%

of rated thermal power.

On February 6,

reactor power was reduced to 90% to accommodate Main Turbine Control Valve testing.

On February 16, reactor power was reduced briefly to 75% to support a control rod pattern adjustment.

On i

February 18, reactor power was reduced to 73% to support isolation of the

'6B' feedwater heater for corrective I

maintenance on the bleeder trip valve.

On February 22, reactor power was reduced briefly to 90% due to high turbine backpressure.

On February 23, reactor power was reduced briefly to 90% to return the '6B' feedwater heater to service and to support a control rod pattern adjustment.

Limerick Unit 1 ended the month of February at a nominal 100% of rated i

thermal power.

Operational events that occurred during the month of February included:

On February 28, HV-050-1F005, RCIC Vacuum Tank Condensate Drain to Radwaste, was found closed with the handswitch I

in the open position.

Investigation revealed that the normally energized solenoid was deenergized.

The solenoid was found to have burned out.

HV-050-1F005 was then blocked open under Supervisory Permit.

On' March 1, HV-049-1F025, Drain Pot Inboard valve failed closed. A burned out solenoid on the valve actuator was found and t

RCIC was declared inoperable.

An air jumper was installed per TCA to maintain HV-049-1F025 open.

On March 2,

HV-409-1F026, RCIC Drain Pot Outboard valve, failed closed.

A burned out solenoid was again the cause.

It was determined that the solenoids had failed due to

'AC' solenoids being installed on the valves l

instead of the 'DC' solenoids.

These solenoids had been L

replaced to meet EQ program maintenance during the Unit 1 RCIC outage on February 19 through 22.

The solenoids have subsequently been replaced.

Challences to Main Steam Safety Relief Valy_gg i

1 There were no challenges to the Main Steam Relief Valves I

during the month of February.
