SUMMARY
NOVEMBER 1985 UNIT ONE 4
Unit One started the month of November operating at 97% power limited by the high level in the "A" once through steam generator (OTSG).
At 0250 hours0.00289 days <br />0.0694 hours <br />4.133598e-4 weeks <br />9.5125e-5 months <br /> on the ninth, power was reduced to 40% to conduct maintenance on the "A" main feed pump (MFP), because of pump speed oscillations.
At 0705 hours0.00816 days <br />0.196 hours <br />0.00117 weeks <br />2.682525e-4 months <br /> on the twelfth, the unit was back up to 96% power, limited by the high level in the "A" OTSG.
On the thirteenth at 1535 hours0.0178 days <br />0.426 hours <br />0.00254 weeks <br />5.840675e-4 months <br />, there was a plant runback to 44% power, caused by a spurious control signal being accidentally sent to the integrated control system during maintenance activities on the feedwater controls.
