| Title | Failure to Follow Compliance Work Order for Corrective Maintenance on Safety Related Equipment |
| Description | The inspectors indentified a Green noncited violation of Unit 1 Technical Specification 5.4.1.a for a failure to perform proper placekeeping and to revise a compliance work order for the replacement of the auto-manual pushbutton, PB-2613, emergency feedwater steam admission valve. Specifically, the electrician had completed critical steps in a compliance work order without following the work order as written as required in Section 5.15 of station Procedure EN-MA-101, Fundamentals of Maintenance, Revision 9. The electricians also failed to stop and revise the work order when encountering an unexpected wiring configuration that was different than was specified in the work order. This was also not in accordance with the station Procedure EN-MA-101. The licensee took immediate corrective action to restore compliance. This issue has been entered into the corrective action program as Condition Reports CR-ANO-C-2011-0284, CR-ANO-C-1695, and CR-ANO-C-2011-1673. The inspectors determined that the failure to follow and revise the compliance work order as required by station Procedure EN-MA-101, Fundamentals of Maintenance, Revision 9, was a performance deficiency because it was within the licensees ability to foresee and correct and is also a violation of technical specifications. The performance deficiency was determined to be more than minor because it was associated with the human performance attribute of the Mitigating System Cornerstone and adversely affected the cornerstone objective to ensure availability, reliability and capability of systems that respond to initiating events to prevent undesirable consequences and is therefore a finding. Specifically, not following compliance work orders while working on safety related equipment could adversely affect the system or component if required to respond to an event. Furthermore, working on safety related equipment without proper procedural guidance could also adversely affect the system or component. Using Manual Chapter 0609, Exhibit 1, Phase 1 Initial Screening and Characterization of Findings, the finding was determined to be of very low safety significance (Green) because it did not result in the loss of operability or functionality; did not represent a loss of system safety function; did not represent an actual loss of function of a single train for greater than its technical specification allowed outage time; did not represent an actual loss of safety function of any risk significant system for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />; and did not screen as potentially risk significant due to external events. The finding was determined to have a cross-cutting aspect in the area of human performance, associated with work practices in that the licensee failed to use human error prevention techniques, such as self and peer checks, and questioning attitude, to ensure that the compliance work order was being followed and revised as required. |
