J. G. Koppler letter to B.
Lee, Jr.
dated March 12, 1979
Dear Mr. Keppler:
Reference (a) transmitted IE Bulletin 79-03 regarding welding defects in certain longitudinally welded pipe spools.
In accordance with that bulletin, we have reviewed the LaSalle County 51ation piping specifications and supplied material and determined the following:
1.
Only seamless ASME SA-312 or electric-fusion welded ASME SA-358 is permitted to be used in safety-related systems.
2 Piping supplied for the NSSS does not contain SA-312 material.
3.
Piping supplied for balance of plant aafety-related systems does not contain questionable SA-312 material from Youngstown Welding and Engineering Co.

Commonwealth Edison NRC Docket Nos. 50-373/374 Mr. James G. Keppler:
2-May 10, 1979 r
Based on this review, we conclude that ASME SA-312 stainless steel pipe welded without filler metal manufactured by Youngstown Welding and Engineering Company is not in use or planned for use in safety-related systems at LaSalle County Station Units 1 and 2.
Please address any questions you may have concerning this matter to this office.
Very truly yours, Cordell Reed Assistant Vice-President cc:
