MONTHLY REPORT FOR BRAIDWOOD UNIT 2 A.
Summary of Operating Experience Braidwood Unit 2 entered the month of October 1993 at approximately 100% capable. The Unit tripped on October 3,1993, as a result of a failed feedwater regulating valve positioner. The positioner was rebuilt and the Unit retumed to service on October 13,1993, operating routinely through the end of the month. The Station continues to monitor RCS activity levels to monitor status of a small fuelleak present since beginning of this refuel cycle.
