1. Monthly R6,$ ort for Braidwood Unit 2 A. ' Sunstry_oL0 pent.ing_Lxperlene Braidwood Unit 2 entered the month of May, 1992 at approximately 99.5% power. The unit operated routinely througn May 8, 1992. Load was reduced on May 9 to allow identification of a main condenser tube leak. Load was reduced on May 15 to allow repair of the leak identified on May 9. On May 17 load was further reduced to make a containment entry to find sources of inleakage to the PRT.

The unit was shut down on May 23 to repair a leak identified on May 21. The unit remained shut @ wn th ough the end of the month.
