June 13 With all three Reactor Coolant Pumps running and RCS temperature and pressure at 525'F and 1500 psig will begin heatup to normal temperature and pressure. At 2230 hours0.0258 days <br />0.619 hours <br />0.00369 weeks <br />8.48515e-4 months <br /> RCS temperature and pressure of 540*F and 2235 psig were achieved.

June 14 Holding RCS temperature and pressure at 547'F and 2235 psig for the performance of surveillance testing.

June 15 During the performance of RCS Full Flow Measurement testing, 1207 hours0.014 days <br />0.335 hours <br />0.002 weeks <br />4.592635e-4 months <br />, Reactor Coolant Pump 1A was shutdown due to high thrust bearing temperatures. At 1815 hours0.021 days <br />0.504 hours <br />0.003 weeks <br />6.906075e-4 months <br /> began to cool down the RCS to Cold Shutdown mode 5 for repair of the 1A Reactor Coolant Pump.

June 16 At 0410 hours0.00475 days <br />0.114 hours <br />6.779101e-4 weeks <br />1.56005e-4 months <br /> the station entered Hot Shutdown mode 4. The Residual Heat Removal system was placed back in service at 1031 hours0.0119 days <br />0.286 hours <br />0.0017 weeks <br />3.922955e-4 months <br />, at 1229 hours0.0142 days <br />0.341 hours <br />0.00203 weeks <br />4.676345e-4 months <br /> the station entered Cold Shutdown mode 5 and at 1229 hours0.0142 days <br />0.341 hours <br />0.00203 weeks <br />4.676345e-4 months <br /> the containment vacuum was broken.

June 17 Shutdown the 1C Reactor Coolant pump at 1125 hours0.013 days <br />0.313 hours <br />0.00186 weeks <br />4.280625e-4 months <br /> on June 17th .

through to bring down RCS temperature and pressure to 120*F and 200 psig June 21 in preparation for LA Reactor Coolant pump thrust bearing work.

NARRATIVE

SUMMARY

OF MONTHLY OPERATING EXPERIENCE - JUNE,1982 June 22 Began heating up RCS to about 120'F psig for future operation through of the 1C Reactor Coolant pump.

June 23 June 24 Began pressurizing the RCS to 320 psig. At 0615 hours0.00712 days <br />0.171 hours <br />0.00102 weeks <br />2.340075e-4 months <br />, during a vibration check, the IB Reactor Coolant pump was found to have a bad seal, so the pump was shutdown.

June 25 At 1700 hours0.0197 days <br />0.472 hours <br />0.00281 weeks <br />6.4685e-4 months <br /> the B Reactor Coolant Loop was isolated to begin draining and at 1932 hours0.0224 days <br />0.537 hours <br />0.00319 weeks <br />7.35126e-4 months <br /> draining began. A 90 minute test run on the LA Reactor Coolant Pump thrust bearing temperature was performed with good results.

June 26 At 0335 hours0.00388 days <br />0.0931 hours <br />5.539021e-4 weeks <br />1.274675e-4 months <br />, the B Reactor Coolant Loop Stop Valve Pressurization was placed in service and at 0800 hours0.00926 days <br />0.222 hours <br />0.00132 weeks <br />3.044e-4 months <br /> the B Reactor Coolant Loop was drained.

June 27 Station is in Cold Shutdown mode 5 with RCS temperature and pressure through at about 110*F and 320 psig. Awaiting the completion of maintenance

June 30 work on the 1B Reactor Coolant pump seal to resume heatup.

MAJOR SAFETY RELATED MAINTENANCE - JUNE 1982

1) Overhaul work on the Main Feedwater Pumps [FW-P-1A, IB] is complete.

2) The motor thrustbearing on the LA Reactor Coolant Pump [RC-P-1A] was repaired due to overtemperature.

3) The No. I seal, No. 2 seal runner and upper three segments of the floating ring seal on the IB Reactor Coolant pump were replaced and the seal injection and seal leakoff lines were flushed.

4) Motor bearings on Component Cooling Water Pump 1B [lCCR-P-1B] were replaced and the motor was realighned.

5) Realighned Component Cooling Water Pump 1C [lCCR-P-lC] and replaced motor bearings that were damaged from the lack of lubrication due to a low motor oiler which had been accidentally stepped on.
