Specify in Abstract below or in Two qualified technicians were performing this activity. The cables that were switched were correctly labeled as "REC I CH 3" and "REC 2 CH 3." Both Step 7.1.6.7 and Step 7.1.7.6 were required to be concurrently verified. The technicians failed to positively identify the correct recorder cable ends prior to performing the steps and failed to vocalize and repeat back the cable identification nomenclature to ensure the correct cables had been selected. This rendered the concurrent verification ineffective.

Although properly labeled, the technique employed did not include reference to the specific procedure steps which directed cable installation. As a result, the cables could easily be switched. More effective labeling could have reduced the potential for this event.

Safety Assessment

The safety significance of this event was minimal. EDG 1 started and loaded per design. Unit 1 and 2 equipment functioned per design. There was no interruption of Unit 1 shutdown cooling as a result of this event. Per design, no Unit 2 isolations or actuations occurred.

Corrective Actions

The following corrective actions were completed.

The two technicians were coached and counseled on the importance of using human performance tools in the performance of their duties. The appropriate personnel accountability measures were taken.

A site-wide stand down was conducted to re-focus personnel on the importance of using verification tools properly so tasks would be completed right the first time.

The following corrective actions to prevent recurrence are planned.

0 EDG loading test procedures (i.e., OMST-DG11 R, OMST-DG12R, OMST-DG13R, and OMST-DGl4R) will be revised to provide instructions on flagging cables and to incorporate a method to record cable assignments to respective procedural steps. These revisions are currently scheduled to be completed by September 20, 2012.

Previous Similar Events

A review of LERs and corrective action program condition reports for the past three years did not identify any similar previous occurrences.
