FIRST INTERIM REPORT Description of Deficiency Because of the relatively large amount of weld required for lug attachment, it is suspected that stainless steel pipe (2-inch diameter and less) in the areas where lugs are attached may not meet ASME Code parts NB-NC-ND4200 ovality tolerances and may exhibit burn-thru or oxidation.
Interim Progress b
TVA is investigating this matter to determine the likelihood of the suspected conditions-and to determine if these conditions are attributable to improper workmanship, procedures, or design.
i More information will be forwarded to you in our next report.
