| Title | Improper Installation of Grounding Trucks |
| Description | A finding of very low safety significance was self-revealed when plant operators attempted to install incorrect components (motor test devices instead of bus grounding trucks) into two 4160 volt breaker cubicles during the implementation of a clearance associated with planned maintenance on the 2R station auxiliary transformer. No violation of NRC requirements was identified. The licensee took immediate corrective actions and entered the issue into their corrective action program. The inspectors determined that the performance deficiency affected the cross-cutting area of Human Performance, having work practices components, and involving aspects associated with ensuring supervisory and management oversight of work activities, including contractors, such that nuclear safety is supported. H.4(c) The finding was more than minor because it could reasonably be viewed as a precursor to a significant event. The finding is not suitable for SDP evaluation, but has been reviewed by NRC management and is determined to be a finding of very low safety significance because the repeated attempts to install the wrong components (motor test devices instead of bus ground trucks) into 4160 volt breaker cubicles did not adversely impact the operation of electrical buses 12 and 13, nor did it result in a significant plant transient. Therefore, the finding was considered to be of very low safety significance. (Section 4OA2.3) |
