Title | Breakdown in the Quality Assurance Program for Vogtle 3&4 Construction Project |
Event Description | This is a 10 CFR 50.55 initial notification for a significant breakdown in the Quality Assurance (QA) Program of Chicago Bridge & Iron (CB&I), an agent for the Licensee of the Vogtle 3&4 Construction Project.
In August 2014, deviations were found in sub-modules CA03-06, -08, and -09, which initiated the discovery and evaluation processes for both Part 21 and 10 CFR 50.55 . The conditions were determined to be not reportable by CB&I under 10 CFR 21, but an evaluation of the root cause analysis results concluded that a significant QA program breakdown had occurred that could have produced a defect. No defect has been identified. This initial notification is being made in accordance with 10 CFR 50.55 (4)(iii) and 10 CFR 50.55 (5)(i). The NRC Resident Inspector will be notified. |
