Braidwood Unit I entered the month of Februcry, 1992 at approximately 96% reactor power. The unit has manually shut down on February 5, 1992, to repair a crack in a weld in the Electro-Hydraulle main oil supply line, The enit returned to

service on February 7, 1992. The unit operated routinely

during the rest of the month with no significant outages or power reductions, I
