| Title | Procedure User Errors Result in Loss of an Electrical Bus. |
| Description | A self-revealing NCV of TS 5.4.1.(a), Procedures, was identified in that FENOC failed to properly implement procedures and required actions in planning, tagging, and electrical system operation. A series of procedural use errors in control of maintenance, equipment control and electrical system operation resulted in the inadvertent loss of the 1G 4160VAC (4kV) electrical bus. The licensee remediated the operating crew and communicated station expectations regarding organizational interfaces and procedural compliance. This was also communicated to all station crews, maintenance, and construction services departments. This finding is more than minor because it is similar to Inspection Manual Chapter (IMC) 0612, Appendix E, example 3b, since the procedural use errors resulted in the loss of the 1G Bus. Traditional enforcement does not apply because the issue did not have an actual safety consequence or the potential for impacting NRCs regulatory function, and was not the result of any willful violation of NRC requirements. In accordance with IMC 609, Attachment 609.04, Phase 1 - Initial Screening and Characterization of Findings, the finding was determined to be of very low risk significance. The cause of this finding is related to the cross-cutting area of human performance, in that FENOCs failed to follow station procedures resulting in a loss of the 1G bus [H.4.(b)]. (Section 4OA2.1) |
