ENCIDSURE HARTSVILLE AND PHIPPS BEND NUCLEAR PLANIS FILLET WELD MISSPECIFICATICN HTRD-50-518, -519, -520, -521/81-01 PBRD-50-553, -554/81-01 10 CFR 50.55(e)
REPORT NO. 1 (INTERIM)
Description of Deficiency In a number of TVA nuclear plant systems, fillet welds were specified, in lieu of beveled groove welds, to connect members whose angle of intersection is outside the limits for fillet weld application as stipulated-in the American Institute of Steel Construction (AISC) Standards. 'Ihe AISC Standatti states that the welds which are made joining members at an angle of 600 or less are to be defined as acute angle welds. Acute angle welds should be specified as beveled groove welds according to AISC.
Interim Procress TVA is in the process of evaluating the AISC Standards and the affected welds in order to determine a satisfactory resolution.
