Licensee Action on Previous Inspection Findings (Closed) Unresolved Item (483/79-12-01) - Code classification of welds:
The inspector reviewed the ASME Code committee interpretation regarding this unresolved matter and determined them to be acceptable and have no further questions on this matter at this time.
(Closed) Noncompliance Item (483/80-02-01) - Weld material control:
The inspector reviewed the revised procedures and the monitoring records.
It was determined that they are acceptable.
(Closed) Unresolved Item (483/80-02-02) - Indication on inside surface of weld: The inspector reviewed Westinghouse Electric Corporation and the licensee's disposition of this unresolved matter and has no further ques-tions at this time.
(Closed) Unresolved Item (483/80-04-01) - SD Radius bend in excess of 90 degrees: The inspector reviewed the nonconformance report which was initiated after it was determined that the misalignment exceeded the specification tolerances. The inspector determined that the corrective action taken appeared to be adequate; however, no action was indicated to prevent recurrence. The inspector stated that some form of corrective action to prevent recurrence should have been taken and emphasized that more attention be given in closing future NCR's.
