| Title | Part 21 - Piping Spool Weld Nonconformance |
| Event Description | The following is an excerpt from WECTEC LLC received via email:
Based on information contained in nonconformance and disposition (N&D) report, a piping spool that was supplied to Aecon Industrial for use in a portion of the Chemical and Volume Control System (CVS) for the V. C. Summer Unit 2 AP1000r project was found to have a weld with an underfill condition. The piping spool was fabricated by CB&I Laurens based on a purchase order from WECTEC LLC. The identified weld defect is associated with a Safety Class B piping spool as part of the containment penetration boundary for the CVS makeup line. Evaluation of the nonconforming weld condition was inconclusive, and therefore, this condition is conservatively assumed to result in the potential failure of the associated containment penetration if it had been left uncorrected. |
