The inspector also talked with and interviewed several other licensee and contractor employees, including members of the Quality Control and craft.
Licensee Action on Previous Inspection Findings (Closed) Unresolved Item (2.!/79-08-03): Incorrect welding process. The inspector reviewed the new seld process data sheet for weld No. E11-3158-0W4 and established that this weld has been cut out and re-welded. The other welds with similar situation identified by Daniel International Corporation during their audit were also corrected by either requalifying the welder or the welding procedure and the DDRs were properly closed except DDR (W) 3423.
The density of the RT film of the test coupon was in question and the licen-see plans to reshoot the test coupon.
-(Closed) Unresolved Item (341/79-20-01): Weld crown reinforcement. The I
inspector reviewed the DDR initiated for this item.
It was determined that corrective action to prevent recurrence has been taken. However, the DDR is open because actual repair of the weld has not been completed.
