Contrary to the above, on November 30, 1984, general procedures for control of repair work were not properly implemented in that:
inconel welding wire was stored with identically. boxed stainless steel welding material in the warehouse and_ tool room; warehouse personnel and tool room personnel entered
.a heat number for inconel material on a stainless steel Inventory Material
. Request and Weld Material Requisition and issued inconel material - for stainless steel; and-the welder did not verify the type of welding material issued.. These procedure violations resulted in inconel material, in lieu of the required stainless steel, being used to weld 2 1/2 passes on RECIRC system overlay weld 28-A-10.
This is a Severity Level IV violation (Supplement I).
RESPONSE
Admission or denial of alleged violation: The violation occurred.
Reason for-the violation:
The welding of inconel material on Recirc system overlay weld 28-A-lO, In lieu of the required stainless. steel, was the result of a series of personnel errors involving a' failure to ~ follow procedure.
The inconel material was -improperly stored and issued in both the warehouse and toolroom due to a failure to pay attention to detail' by key personnel.
Welding personnel incorrectly assumed that because the inconel spools of' wire were packaged in boxes identical to the boxes of stainless. steel wire, only stainless steel spools were available.
Corrective steps which have been taken and the results~ achieved:
A Limiting Condition for Operation (LCO) was initiated -upon discovery.
The inconel filler was ground out and the affected area acid etched to. verify total removal of the inconel per procedure HNP-1-10273.
All warehouse, toolroom, and welding ' personnel involved ~ were counselled by their supervisors.
In addition, the responsible personnel participated in a seminar on performance.
of the weld material control procedure and attention to. detail.
' Corrective steps which will be taken to avoid future violations:
The above actions are-sufficient to prevent recurrence.
