| ENS 51158 | 17 February 2015 12:00:00 | 10 CFR 50.55(e) | Quality Assurance Programmatic Issues | 10 CFR 50.55(e) initial notification for a failure to comply with requirements of 10 CFR 50 Appendix B associated with AP1000 nuclear power plant construction by Chicago Bridge & Iron Company (CB&I) at the V.C. Summer Units 2 & 3 construction site. This 50.55(e) initial notification addresses a failure to comply by CB&I, an agent of South Carolina Electric & Gas Company (SCE&G) for V.C. Summer Units 2 & 3, to meet the requirements of Appendix B, Criteria V and XV. It is concluded that Quality Assurance programmatic issues, as identified by CB&I Root Cause Analysis 2015-0539, could have produced a defect and this condition is reportable in accordance with 10 CFR 50.55(e)(3)(iii)(C). Root Cause Analysis 2015-0539 investigated the causes that lead to impingement of safety related reinforcing steel and the steel containment vessel during concrete core drilling operations within the Unit 2 containment structure. No defect has been identified. This condition is associated with NRC special inspection report number 05200027/2015-009. This notification closes the Interim Part 21 report submitted on April 16th, 2015, by CB&I. This 50.55(e) Initial Notification is being submitted pursuant to the requirements of 10 CFR 50.55(e)(3)(iii)(C). The licensee notified the NRC Resident Inspector. | ||
| ENS 50815 | 25 August 2014 12:00:00 | 10 CFR 50.55(e) | Breakdown in the Quality Assurance Program for V. C. Summer 2 & 3 Construction Project | 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 V. C. Summer 2 & 3 Construction Project. In August 2014, deviations were found in sub-modules CA03-06, -08, and -09 for the Vogtle 3 Construction Project, 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(e)(4)(iii) and 10 CFR 50.55(e)(5)(i). The NRC Resident Inspector has been notified.". | ||
| ENS 50442 | 13 March 2014 12:00:00 | 10 CFR 50.55(e) | Welding Program Deviations During Construction | This is a 10CFR50.55(e) initial notification for a significant breakdown in the Quality Assurance (QA) program of Chicago Bridge & Iron (CB&I) Lake Charles facility, a sub-supplier of CB&I. CB&I Lake Charles supplies safety-related structural sub modules for the Virgil C. Summer Units 2 and 3 construction project. In March, 2014, CB&I Lake Charles issued a root cause analysis report for welding program deviations associated with the fabrication of sub-modules being supplied to domestic AP1000 construction projects. 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 10CFR50.55(e)(4)(iii) and 10CFR50.55(e)(5)(i). The licensee notified the NRC Resident Inspector. | ||

CB&I Lake Charles supplies safety-related structural sub modules for the Virgil C. Summer Units 2 & 3 construction project. In September 2013, CB&I Lake Charles issued a root cause analysis report for deviations associated with sub-modules being supplied to domestic AP1000 construction projects. 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(e)(4)(iii) and 10 CFR 50.55(e)(5)(i). The licensee will notify the NRC Resident Inspector. | ||
| ENS 48910 | 6 December 2012 12:00:00 | 10 CFR 50.55(e) | Failure to Comply with Conditions of Construction Permit | 50.55(e) initial notification for failure to comply with requirements of 10 CFR 50 Appendix B, Criterion VII for procurement of safety-related components associated with AP1000 Nuclear Power Plant construction by CB&I (formerly Shaw Nuclear). This 50.55(e) initial notification addresses a failure to comply by CB&I, an agent of South Carolina Electric & Gas (SCE&G) for Virgil C. Summer 2 & 3, to meet the requirements of Appendix B, Criterion VII. It is concluded that the QA programmatic issues, as identified by the root cause analysis associated with NRC violation 05200025/2012-004-02, could have produced a defect and this condition is reportable in accordance with 10 CFR 50.55(e)(3)(iii)(C). The root cause of the programmatic procurement problems was that the existing Shaw Nuclear procurement and quality oversight and inspection program did not include a sufficiently strategic, integrated, and graded approach to assure the required quality of material, equipment, and services. This notification closes the interim report submitted on February 4, 2013 by SCE&G. This 50.55(e) initial notification is being submitted pursuant to the requirements of 10 CFR 50.55(e)(3)(iii)(C). The licensee has notified the NRC Resident Inspector. |
