SUMMARY

OF OPERATING EXPERIENCES APRIL, 1980 UNIT 2 OPERATIONS The unit remains shutdown to accommodate refueling, modifications, and maintenance work. The removal of fuel from the reactor was completed on April 6. Changeout and verification of LPRMS was completed on

• April 8, 1980. Control rod blade changeout was completed on April 14.

Oraining and decontamination of the torus to accommodate modifications was completed April 11. The control rod blade exchange and ISI were completed on April 15. The draining and decontamination of the reactor well was completed on April 16. Upon completion of the uncoupling of 37 control rod drives and shutdown of the CRD system on April 21, the reactor vessel water level was lowered to facilitate installation of new design feedwater spargers and perform core spray system pipe replacement external to the reactor vessel .

UNIT 3 OPERATIONS On April 3, a load reduction to approximately 660 MW was begun in order to replace a limit switch on one of the main turbine control valves.

The control valve was " failed closed" and the limit switch was replaced.

Following this the valves were tested and the unit returned to full power by April 4. During this reduced power operation, a condenser Icak was also corrected. On April 8, the 3A reactor feed pump turbine tripped due to high vibration. This required a load reduction to approximately 940 MWe, After the reactor system was stabilized, load was increased to approximately 1055 MWe. This limit was maintained until early on. April 11, when the unit was returned to full load.

On April 12, a load reduction of 100 MWe was made so that the other two feed pumps could be taken out of service one at a time to accomnodate lubricating their couplings. On April 13, the Unit 3D RHR pump s0ction line was discovered to have a leak at a drain tap.

The pump was declared inoperable and appropriate surveillance tests were successfully completed. A cracked weld on the drain tap was suc-cessfully repaired and the pump was restored to service. On April 23, during testing of turbine valves,' the No. 1 Combined Intercept Valve closed but did not " disc dump" and fast close through the last few percent of its travel. The problem was determined to be with an electrical coil which operates a solenoid on the valve. The coil was replaced on April 25 and the valve was satisfactorily tested.
