NIAGARA M0 HAWK POWER CORPORATION NINE MILE POINT - UNIT 2 DOCKET NO. 50-410 Interim Report for a Problem Concerning Unqualified Weld Filler Material (55(e)-85-16)
Description of the Problem The welding of attachments to the primary containment liner requires the use of weld filler material quali fied by impact testing.
- However, welded attachments to the liner were made using an unapproved grade of weld filler material which was not impact tested.
Also, since an unapproved grade of weld filler material was used, the welding procedure was no longer qualified.
The matter is still under investigation, and a final report will be submitted by December 2, 1985.
