s CATAWBA NUCLEAR STATION REPORT NUMBER: SD 413-414/81-09 REPORT DATE: June $, 1981 FACILITY: Catawba Nuclear Station, Unit 1 IDENTIFICATION OF DEFICIENCY: Fillet welds incorrectly specified. INITIAL REPORT: On May 8,1981, Mr. J. Bryant of Region 11 was notified of this deficiency by Mr. W. O. Henry of Duke Power Company, Charlotte, NC 28242 DESCRIPTION OF DEFICIENCY: During fitup, improper weld sizes were found to have been issued on some welding process control. When the undersized welds were found at fitup and returned for correction, the weld sizes were again incorrectly specified: Two welds (1 SA 31-1 and 1 SA 31-2) were found to be undersized and in violation of design criteria (ASME Section 111). These welds are further identified as follows: Sys: SA-Main Steams Supply to Auxiliary Equipment Loc: Auxiliary FDW Pump Turbine Exhaust Piping Size: " 0.D. Sch. 80 Code: ASME Section lil, Class ll, Duke Class B l SAFETY IMPLICATIONS: Failure to indicate the proper size welds on process control could result in undersized welds that would not be detected during inspection. This condition might result in failure l of system function or reduced conservatism. l CORRECTIVE ACTION: The process control forms are originated and checked to insure accuracy. Personnel performing these functions will be retrained in the need for accuracy and independent second checks of this work. T raining will be completed by July 1,1981. l l 9PT k}}
