I ENCLOSURE BELLEFONTE NUCLEAR PLANT UNIT 1 DEFICIENT WELD 0LETS ON NAVC0 SPOOL PIECES NCR 1740 - BLRD-50-43B/82-19 10 CFR 50.55(e)
SECOND INTERIM REPORT Description of Deficiency Five weldolets on spool pieces 1ND-196,1ND-198,1ND-200,1ND-202, and 1NV-242 exhibit welds that do not conform to the ASME Code Section III Subsection NB (for class 1 components) or Subsection NC (for class 2 components) requirements for fabrication. The welds are typically below flush 1/64 inch to 3/32 inch. In addition, a weld at the upper apex of a special thermowell boss on spool piece 1NV-241 was ground down below flush. The subject weldolets are installed in the Decay Heat Removal (ND) System and Makeup and Purification (NV) System piping.
The vendor of these items was National Valve and Manufacturing Company (NAVCO) of Pittsburgh, Pennsylvania.
Interim Progress TVA is investigating an apparent discrepancy between the weld requirements for the subject weldolets specified in the ASME Code and TVA's site inspection procedures outlined in General Construction Specification G-29C, " Process Specifications for Welding, Heat Treatment, Nondestructive Examination, and Allied Field Fabrication Operations." TVA will supply additional information on this deficiency upon completion of this investigation.
