SUMMARY

OF OPERATING EXPERIENCE FOR OCTOBER 1995 The unit began the month at 100% power.

A slight power decrease occurred on 10/22-23/95 due to indications of turbine governor valve movements.

Visual inspection showed very little movement occurred, and #3 Governor Valve servo was found to have a broken wire, similar to an incident that happened last cycle.

Power was returned to 100% until 10/28 2038 hours0.0236 days <br />0.566 hours <br />0.00337 weeks <br />7.75459e-4 months <br /> when a

power reduction was made to support turbine governor val Vl= repairs.

At 0212 on 10/29 during valve repairs, unexpected governor valve movement caused a step change to 73%,

where power was stabilized.

Power was stabilized at 73%.

Power was returned to 8 6% for further work on the remaining valves.

Power escalition to 100% began on 10/30 at 0400 hours0.00463 days <br />0.111 hours <br />6.613757e-4 weeks <br />1.522e-4 months <br /> and the reactor reached 100%

power at 0643 hours0.00744 days <br />0.179 hours <br />0.00106 weeks <br />2.446615e-4 months <br /> for the remainder of the month.
