II. Monthly Report for Braidwood Unit 2 A. Summarv of Operatino Exoerience The unit entered the month of March in Mode 3. On March 8 at 1150 the unit reached initial criticality and by March 14 the unit was at 3% reactor power. On March 16, the reactor was shut down due to main generator seal leakage and to replace Limitorque valve operator grease based on environmental qualification concerns. The unit remained in Mode 5 through the end of the month.
