Response
M Ultrasonic testing (UT) performed on the #3 Control Rod Drive Mechanism (CRDM) nozzle p
(location G9) revealed Indications of through wall axial flaws in the weld region. CR 02-00891 L
was Issue to document this condition. Response to the CR will evaluate crack size, location and E
other aspects of the failure. Boric acid found on the reactor head did not originate from CRDM M
flanges. This was verified by videotape examination of CRDM flanges performed by FTlISYME on E
2/25/02 and 2/26/02. Since all aspects of nozzle cracking will be discussed In CR 02-00891 N
response, this CR 02-00685 is dosed to CR 02-00891.
