e ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 INCORRECT INSPECTION CODE ON HANGER DRAWINGS BY ITT GRINNELL NCR 1748 BLRD-50-438/82-24, BLRD-50-439/82-21 10 CFR 50.55(e)
THIRD INTERIM REPORT Description of Deficiency During a review of weld documentation and pipe hanger drawings, plate and shell welds on safety-related hangers were discovered which did not receive a dye-penetrant inspection as required in ASME Section III, Class 2,. Subsection NF.
Two causes for this deficiency were determined.
1.
Inspection requirements were overlooked by TVA personnel reviewing the hanger drawings to generate the automated process control (APC) weld cards used in construction of the support.
2.
TVA's hanger vendor (ITT Grinnell, Providence, Rhode Island) specified some ASME Section III, Class 2, welded joints to the wrong inspection code paragraphs (NF-5231, etc.).
The vendor portion of this NCR is not applicable to other TVA plants since ITT Grinnell has a hanger contract only with Bellefonte. The improper inspection of the hanger drawings for weld inspection requirements may be of generic nature; and therefore, the NCR will be directed to other plants for consideration.
Interim Progress TVA's Division of Construction has completed the review of all weld documentation and hanger drawings for ASME Section III, Class 2 supports to determine if the proper weld inspections were performed. Sixty-three of the welds reviewed will require reinspection.
Reinspection of these welds will be initiated. To prevent recurrence of this deficiency, a second review of the APC weld cards is now performed before their issue for use.
ITT Grinnell has performed an initial review of the ASME Section III, Class 2 hangers listed in the NCR for adequacy of the specified inspection code. TVA is reviewing the deficiency and working with the vendor on a resolution.
