NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE 1

I MONTH: FEBRUARY 1996 For February Unit 2 was base loaded, there were no shutdowns and only one power reduction.

On Saturday, the 10th, at 0213 the Unit started a ! cad reduction, to approximately 40% reactor i

power, to clean condenser tubes and Amertap screens. During this period a turbine valve test was also conducted. On the 11th at 0220 the Unit started to retum to full power operation when I

turbine control valve, CV-4, closed unexpectedly. The power ascension was halted and power was held at approximately 71% until valve repairs were completed. The valve was repaired by 1040 and by 1330 the Unit was at full power operation.
