ll-NRC MONTHLY OPERATING REPORT Operating Summary - February,1979 UNIT I The Unit was placed on line following repair of the Low Pressure Turbine.

It was necessary to rebalance the turbine during startup. The Unit opera-tion proceeded to 100% reactor power and operated without any significant occurrences until 2/9 when the temperature rise across the condenser ex-ceeded the Appendix B Technical Specification limit of 15 DEGF. The high temperature rise was due to a restriction of circulating water flow caused by a collection of trash and fish on the inlet tube sheets. The circulat-ing water inlet valves are being cycled, as necessary, to allow debris to wash off; thus improving the flow rate. (Reference Non-Routine Report No.

50-313/79-1.) On 2/15, the power level was reduced for a short period of time to allow maintenance on the P8 A and B heater drain pumps. The Unit operated throughout the remainder of the month without incident.
