_y ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 FAILURE TO IMPACT TEST SUPPORT MATERIALS BLRD-50-438/84-36, BLRD-50-439/84-33 NCR BLN CEB 8407 10 CFR 50.55(e) FIRST INTERItt REPORT t Description of Deficiency Bellefonte pipe support material impact test requirements are specified by the ASME B&PV Code Section III, subsection NF-5211, and Bellefonte Design Specification BLNP-DS-1915-2992-01. From these sources, ASME safety classes 1, 2, and 3 seismic pipe supports located in areas where the ambient service temperature can fall below 400F are required to be constructed from materials meeting impact test requirements. Due to misinterpretation of the Bellefonte design specification, various pipe supports in such areas are constructed from materials not qualified to impact test requirements. Interim Progress TVA is currently reviewing the deficiency to identify all nonconforming materials used. TVA will then evaluate the nonconforming materials to determine the corrective action. 9 e ,}}
