SUMMARY
NOVEMBER 1995 UNIT TWO The month began with the unit offline for refueling outage 2R11.
At 1540 hours0.0178 days <br />0.428 hours <br />0.00255 weeks <br />5.8597e-4 months <br /> on the thirteenth, the plant heatup was halted due to leakage in the body to bonnet seal weld for pressurizer high point vent valve 2SV-4636-1. The unit was cooled back down in order to allow repair of the seal weld. Upon completion of this repair, plant heatup was resumed at 2035 hours0.0236 days <br />0.565 hours <br />0.00336 weeks <br />7.743175e-4 months <br /> on the fourteenth. A second cool down was initiated at 2036 hours0.0236 days <br />0.566 hours <br />0.00337 weeks <br />7.74698e-4 months <br /> on the sixteenth due to leaks on pressurizer spray valve 2CV-4651 and a blank flange on the top of the pressurizer. After the leaks were repaired, heatup was again resumed at 2145 hours0.0248 days <br />0.596 hours <br />0.00355 weeks <br />8.161725e-4 months <br /> on the eighteenth. The reactor attained criticality at 0412 hours0.00477 days <br />0.114 hours <br />6.812169e-4 weeks <br />1.56766e-4 months <br /> on the nineteenth, and the unit was placed on line at 0447 hours0.00517 days <br />0.124 hours <br />7.390873e-4 weeks <br />1.700835e-4 months <br /> on the twentieth marking the end of the refueling outage.
At 1146 hours0.0133 days <br />0.318 hours <br />0.00189 weeks <br />4.36053e-4 months <br /> on the twentieth, the unit was taken off lino to perform the main turbine overspeed trip test. Main turbine generator lockout relays 286-G2-8 and 286-G2-9 failed to reset and the test was halted at 1150 hours0.0133 days <br />0.319 hours <br />0.0019 weeks <br />4.37575e-4 months <br />. It was discovered that 286-G2-8 had a design flaw that would not allow it to be reset after it had been tripped.
After de-energizing the trip signal being sent to 286-G2-8, the lockout relays were able to be reset and the main turbine overspeed trip test was continued at 1708 hours0.0198 days <br />0.474 hours <br />0.00282 weeks <br />6.49894e-4 months <br /> on the ~wentieth.
The test was completed at 1900 hours0.022 days <br />0.528 hours <br />0.00314 weeks <br />7.2295e-4 months <br /> and work to modify 286-G2-8 lockout rey was started. Modifications to lockout relay 286-G2-8 were completed and the unit was ph ced on line at 2230 hours0.0258 days <br />0.619 hours <br />0.00369 weeks <br />8.48515e-4 months <br /> on the twenty-first. The unit performed normal power ascension to 30%
until 1710 hours0.0198 days <br />0.475 hours <br />0.00283 weeks <br />6.50655e-4 months <br /> on the twenty-second when the unit was taken off line due to excessive leakage past the main generator hydrogen seal. Following repairs to the seal, the unit was placed on line at 0102 hours0.00118 days <br />0.0283 hours <br />1.686508e-4 weeks <br />3.8811e-5 months <br /> on the thirtieth. The month ended with the unit at 30% power.
