Review of Nonroutine Event Reported by the Licensee Tne inspector reviewed licensee actions with respect to the below listed Reportable Occurrence (RO).
This review was to verify that the event was reviewed and evaluated by the licensee as required by Technical Specifications.
The inspector examined Operations Comittee minutes, material test reports, nondestructive examination reports, and interviewed selected personnel. The R0 reviewed and the inspection findings were as follows:
R0-79-1/lP: Butt-weld failure in the Reactor Water Cleanup System return line (loop "B").
The licensee's corrective action, delineated in Job Order package No. R-013-79, involves complete removal of the defective weld.
This was acccmplished by cutting through two welds Nos. CUBJ-10 and CUBJ-11 (the failed weld) and removing an 18" long section of pipe.
Preliminary evaluation by the licensee indicates the probable cause of failure to be intergranular stress corrosion cracking.
However, a metallographic analysis will be performed to determine the exact cause of failur.
The inspector audited documentation associated with this repair to verify compliance with procedural / specification requirements.
Based on this audit and discussions with cognizant personnel the inspector determined that repairs were-being made as stipulated in the Job Order package.
The inspector has no further questions regarding this repair at this time.
