Licensee Action on Previous Inspection Findings (Closed) Unresolved Item (454/80-07-01) - Shop weld of bellow:
It was determined that the shop weld of the bellow element to the weld end of the pipe spool should be flushed with the pipe spool.
It was established
'
that the licensee has reinspected all such welds and repair was made to three welds thru a rework request. The inspector noted a nonconformance report was not initiated and emphasized that the QA manual requires that a NCR be written.
