-LENGTH OF INCORE MONITORING SYSTEM PIPING AND GAUGE BLRD-50-438/84-05 1
NCR 2684 10 CFR 50.55(e)
FIRST INTERIM REPORT Description of Deficiency All incore monitoring system. piping for unit 1 was cut approximately 1-1/2 inches too long as a result of an error in establishing the length of the gauge used to measure each pipe. The cause of this deficiency was misinterpretation of lengths of the certified chain. The first foot is graduated in tenths of a foot and site engineering and QC persormel interpreted this as inches which resulted in this deficiency.
Interim Progress TVA has submitted a sequence control chart (SCC) to Babcock and Wilcox (B&W) for concurrr.nce of the method to be used in remeasuring all of unit 1 incore piping. Final dimensions will be submitted to TVA's Division of Engineering Design (EN DES) and B&W for their determination of resolution.
Further action will be taken as a result of recommendations made by EN DES and B&W.
