Finding

Title

Failure to Follow Station Work Control Procedure Results in Unavailable Equipment

Description

The inspectors documented a self-revealing finding for station electrical maintenance personnel\'s failure to adequately implement station Procedure ENWM- 102, Work Implementation and Closeout, Revision 4. Specifically, station personnel performing Work Order 00182908-01, removal/reinstallation of the C-8A isophase fan motor, did not stop work and get a scope change for the work order when a condition that was not identified in the work order was discovered. This issue was entered into the licensee\'s corrective action program as Condition Report CR-ANO-1-2010-2260. The performance deficiency was determined to be more than minor because it affected the human performance attribute of the Initiating Events Cornerstone, and it directly affected the cornerstone objective to limit the likelihood of those events that upset plant stability during power operations. Using Manual Chapter 0609.04, Phase 1 - Initial Screening and Characterization of Findings, the inspectors determined that the finding was determined to have very low safety significance because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or function would not be available. The finding was determined to have a crosscutting aspect in the area of Human Performance, associated with work practices in that the licensee failed to communicate human error prevention techniques, such as holding pre-job briefs, self- and peer-checking, and proper documentation of activities.
