SECOND INTERIM REPORT Description of Deficiency An internal lack of fusion, approximately 1/8 inch wide and 21 inches long, was discovered during the installation of a spool piece supplied by NAVCO. This internal lack of fusion was found during the radiography of a circumferential butt weld. The radiograph overlapped an adjacent longitudinal weld of the spool piece and indicated that it exhibited the lack of weld fusion. The spool piece is 12 inches in diameter, stainless steel SA312 TP304 welded pipe located in the Spent Fuel Cooling System.
Correctito Actions TVA is performing an analysis in order to determine the safety significance of this condition. The spool piece has been removed and is being evaluated at TVA's Singleton Materials Laboratory.
