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)
SECOND 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 hunger 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 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 is in the process of reviewing ~ all weld documentation and hanger drawings for ASME Section III, Class 2, supports to determine if the proper weld inspection was performed.
ITT Grinnell is reviewing all ASME Section III, Class 2, supports for adequacy of inspection code specified.
