Subject: Recirculation Riser Piping Weld Crack Repairs
Reportable Event Number: 36416

Discussion:

During routine inspections performed on reactor vessel recirculation
riser piping, the licensee identified two of the eight risers had cracks
in welds. The cracks were in the safe-end to nozzle portion of the "B"
and "D"recirculation risers. There were a total of three cracks
identified. The licensee is currently in the process of performing weld
over-lays at the crack locations. The plant was shut down on October 22,
1999, to initiate refueling outage 16. The weld over-lays will be
completed prior to start-up. Contact: Melvin Leach - (630)829-9705
