BOSTON EDISON COMPANY PILGRIM NUCLEAR POWER STATION DOCKET NO. 50-293 OPERATIONAL SU_MMARY FOR APRIL 1994 The unit started the reporting period at 100 percent core thermal power (CTP) where it was essentially maintained until April 17, 1994 On April 17, 1994, reactor power was reduced to approximately 50 percent CTP to facilitate a thermal backwash of the main condenser, and perform control rod scram time testing. During the testing, at approximately 56 percent CTP, a number of the control rods exhibited an increased 10 percent scram insertion time. Also one control rod (10-31) failed to fully insert within 7 seconds in accordance with the acceptance criteria. This control rod was declared inoperable, fully inserted, and electrically disabled. Disassembly of the control rod's scram solenoid pilot valve, revealed one completely failed exhaust diaphragm and an embrittled and cracked pressure diaphragm. Other control rods which had exhibited slow or degraded scrar insertion times were disassembled and upon inspection revealed diaphragms in various degrees of degradation. On April 20, 1994, while the rod scram time testing continued, reactor power was reduced to approximately 43 percent CTP to facilitate troubleshooting of the Augmented Offgas (AOG) System. On April 22, 1994, following the discovery of additional diaphragms with significant degradation, the decision was made to shut the plant down so that the scram solenoid pilot diaphragms on all 145 hydraulic control units (HCU) could be replaced. At 2321 hours0.0269 days <br />0.645 hours <br />0.00384 weeks <br />8.831405e-4 months <br /> on April 22, 1994, the main turbine was manually tripped off-line, and at 0331 hours0.00383 days <br />0.0919 hours <br />5.472884e-4 weeks <br />1.259455e-4 months <br /> on April 23, 1994, a controlled shutdown of the reactor was completed. Following HCU maintenance, the reactor was made critical at 2245 hours0.026 days <br />0.624 hours <br />0.00371 weeks <br />8.542225e-4 months <br /> on April 28, 1994, and the main generator was synchronized to the grid at 1046 hours0.0121 days <br />0.291 hours <br />0.00173 weeks <br />3.98003e-4 months <br /> on April 29, 1994. Power was increased to approximately 25 percent CTP where it was essentially maintained to perform post work testing of the control rods. On April 30, ,
1994, at 2051 hours0.0237 days <br />0.57 hours <br />0.00339 weeks <br />7.804055e-4 months <br /> the main generator was manually tripped offline to facilitate a weld repair on the extraction steam line entering the train "B" second point feedwater heater.
The unit remained offline for the remainder of the reporting period.
SAFETY RELIEF VALVE CHALLENGES MOiUH OF APRIL 1994 Requirement: NUREG-0737 T.A.P. II.K.3.3 There were no safety relief valve challenges during the reporting period. >
An SRV challenge is defined as anytime an SRV has received a signal to operate via reactor pressure, auto signal (ADS) or control switch (manual) Ref. BECo ltr. #81-01 date 01/05/81.
