ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 BOLTS AND NITIS FAIL TO MEET ASTM SPECIFICATIONS NCR'S 1597 AND 1598 BLRD-50-438/81-64, BLRD-50-439/81-62 10 CFR 50.55(e)
FIFTH INTERIM REPORT Description of Deficiency j
10,000, 3/4" stainless steel nuts (furnished by Chattanooga Bolt and Screw, Chattanooga, Tennessee) and 10,600, 3/4" x 3-1/2" stainless steel bolts (furnished by Challenge Enterprises, Chattanooga, Tennessee) were received not marked in accordance with ASTM specifications. Subsequent testing of the subject material by Singleton Materials Engineering Laboratory revealed the material failed to meet ASTM specifications. The associated documentation received with the material erroneously indicated that the nuts and bolts do meet ASTM specifications. Approximately 450 of these bolts and 1300 nuts have been issued to the field for installation.
Nonconformance report (NCR) 1597 pertains to the bolts and NCR 1598 pertains to the nuts.
Interim Progress After intense investigation and thorough searching for the missing nuts and bolts, TVA has determined that all of the bolts and nuts could not be located. TVA will perform an engineering evaluation to weigh the consequences of providing acceptance to use the bolts and nuts as is based on results of an analysis by TVA's Singleton Laboratory. The analysis results are in, but no engineering interpretations nor recommendations have been made. More information will be provided in our next report.
