Licensee Actions on IE Bulletins (Closed) IE Bulletin (461/83-06-BB):
IE Bulletin 83-06, " Nonconforming Materials Supplied by Tube-Line Corporation." The inspector reviewed the licensee's final response dated June 11, 1985.
IP identified all Tube-Line materials supplied to Clinton Power Station.
The Tube-Line material installed in ASME or safety-related systems was either analyzed and found acceptable for use in the safety-related application or replaced.
A "Potentially Unacceptable Materials Log" has been establi.shed by the licensee to assure that any material purchased and not yet accounted for is detected and reported as an NCR.
This item is considered closed.

The NRC inspector also reviewed quality records, including travelers, NCRs, and welding and NDE reports on the following welds:
Loop A (B33G001A)
Loop B (B33G0018)
Weld Nos. B4, B19
The NRC inspector determined that the specified inspections were completed, weld history records were satisfactory, and that the records reflected adequate weld quality.
During the visual examination, weld splatter (Weld Hos. A7 and B7), rust (Weld Nos. 84, B6 and 88), and hammer marks (Weld No. A8) were noted by the NRC inspector.
As a result, IP issued Condition Report No. 1-85-09-041 to evaluate the severity of the weld spatter, rust and hammer marks.
This is an unresolved item pending NRC review of the IP evaluation.
(461/85034-01)
No violations, deviations or unresolved items other than those discustSd above were identified.

Loop B (B33G0018)-
Weld No. B19 - Linear indication found by P.T. removed by minor
'
buffing Weld No. 84 - Defect found by P.T. removed by minor buffing.
'
The NRC inspector determined that the weld repairs were conducted in accordance with the applicable requirements and specified procedures.
The inspector also reviewed the NDE records and found them to be acceptable.
No violations or deviations were identified.
5.
