Subsequent imrstigation identified that the feedback spring retaining bolt on #21 Main Fced Regulating Vahr positioner had broken, causing the valve to close. The valve was repaired and the unit was returned to operation on 11/20/96 at 0640. The root cause of the trip (broken bolt) is still under imestigation.

SUMMARY
OF OPERATING EXPERIENCE November 1996 The unit began the month at 100% power.
On 11/09/96 at 0357, power was reduced to approximately 95% due to a loss of a circulating water pump.
Power was returned to 100% at 1640.
j On 11/17/96 at 1059 an automatic reactor trip occurred due to a low steam generator water level. Based j
on the indications received, the operators believed that a feedwater regulating valve had closed while operating at 100% power. Subsequent investigation identified that the feedback spring retaining bolt on the positioner for #21 Main Feedwater Regulating Valve had broken. This caused the valve to close and thus caused the trip. Repairs were made to the valve and the unit was returned to operation on 11/20/96 at 0634. The unit reached 100% on 11/21/96 at 0600.
The unit remained at 100% power for the remainder of the month.
