OF OPERATING EXPERIENCE 10-1 At the beginning of the report period the plant was ope ating at 209 MWe. Plant load was administratively limited in order to conserve fuel for winter peak loads. The plant was following load to the extent possible while staying within administrative limits. .
10-3 During surveillance testing "B" rod block monitor (RBM) was found to be inoperable and generating a continuous rod withdrawal block. "A" RBM was tested and found to be operable.
R0 79-028 10-15 The "A" feed pump was started. Plant load was increased due to increasing system demand.
10-20 Plant load was reduced due to lack of demand and to conserve fuel for 1 winter peak loads.
10-23 The "B" feedwater pump seal water return line was found leaking. The leak was in an unisolable location so preparations for a plant shutdown were begun.
10-24 The main generator was tripped at 0117 hours0.00135 days <br />0.0325 hours <br />1.934524e-4 weeks <br />4.45185e-5 months <br />. The reactor was subcritical at 0215 hours0.00249 days <br />0.0597 hours <br />3.554894e-4 weeks <br />8.18075e-5 months <br />. The RCIC turbine was operated from 0348 hours0.00403 days <br />0.0967 hours <br />5.753968e-4 weeks <br />1.32414e-4 months <br /> to 0520 hours0.00602 days <br />0.144 hours <br />8.597884e-4 weeks <br />1.9786e-4 months <br /> for vessel pressure control.
10-25 Repairs were completed and plant startup begun. The reactor was critical.

The main generator was placed on the line at 0607 hours0.00703 days <br />0.169 hours <br />0.001 weeks <br />2.309635e-4 months <br /> and a power increase was begun. The plant was at 388 MWe at 2230 hours0.0258 days <br />0.619 hours <br />0.00369 weeks <br />8.48515e-4 months <br />.
A fuel preconditioning ramp was begun at 2345 hours0.0271 days <br />0.651 hours <br />0.00388 weeks <br />8.922725e-4 months <br />.
10-26 At 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br /> "B" rod block monitor was found inoperable. An R0 investigation is in progress.
During the performance of a special test of standby diesel generator 1G-21, the fuel oil level in the diesel fuel storage tank dropped below the 35,000 gallon technical specification limit. An R0 investigation is in progress. .
10-28 The plant was operating at 508 MWe. ,
10-29 The RCIC system was declared inoperable due to a packing leak on CV-2409.
A seven day LCO was started.
10-30 CV-2409 was repaired and the RCIC system tested with satisfactory results.
The seven day LC0 was cancelled.
10-31 At 2214 hours0.0256 days <br />0.615 hours <br />0.00366 weeks <br />8.42427e-4 months <br /> a turbine trip and reactor scram occurred during turbine stop valve testing. The turbine supervisory instrument system first hit was EHC low pressure. An investigation was begun.
