| Title | Failure to Test of Evaluate the Seismic Critical Characteristic for a Commercial Grade Circuit Breaker |
| Description | The inspectors identified a finding of very low safety significance and an associated non-cited violation of Title 10 of the Code of Federal Regulations, Part 50, Appendix B, Criterion III, "Design Control," for the licensee's failure to verify commercial grade circuit breakers were suitable for use in safety-related applications. Specifically, the licensee failed to verify, either through seismic testing or justification, that the circui
breakers being dedicated on purchase order 02309726 would be able to perform their intended safety function during a seismic event. The licensee entered this finding into their Corrective Action Program as condition report 01986727 and 01987616. An extent of condition review was performed and concluded that these circuit breakers were not yet installed at Duane Arnold and a seismic test would be performed on these types of breakers prior to installation. The performance deficiency was determined to be more than minor because, if lef uncorrected, the performance deficiency would have the potential to lead to a more significant safety concern. Because the finding did not represent an actual loss of function (circuit breakers were not currently installed), the finding screened as very low safety significance (Green). The inspectors did not identify a cross-cutting aspect associated with this finding because the finding was not representative of licensee's current performance. |
