' Contrary to the above, on October 29, 1982, three radiographs approved for the weld number FW12S-SEN were not permanently traceable to the correct system and weld, but were etearly mis-identified as FW11S-SEN.
RESPONSE
1.
The following corrective action was taken to correct the identified violation: All final radiographic packages have been reviewed to verify proper identification.
2.
In addition to the action listed above, Niagara Mohawk Power Corporation will, in the future, identify all welds on the piping in the vicinity of the weld. Also, the radiograph reader sheets will be stamped and signed " Joint ID Verified",
thereby insuring permanent identification traceable to the component, plant and weld seam as required.
3.
Due to these actions, Niagara Mohawk Power Corporation is presently in full compliance.
Very truly yours mff
