| Title | Failure to Follow Station Planning Procedure Results in an Inadequate Work Instructions |
| Description | The inspectors identified a finding associated with a station planners failure to follow procedure which resulted in inadequate work instructions. This is not a violation because the isophase blower is not safety-related equipment. Specifically, contrary to Station Procedure EN-WM-105, Revision 5, Planning the work instructions generated to replace worn parts for isophase blower C-8A, did not provide sufficient details, nor provide references to appropriate instructions which provided sufficient detail, concerning reassembly of the damper positioner. This resulted in the positioner being incorrectly reassembled during the maintenance which caused the damper to not open or shut reliably. The licensee entered this issue into their corrective action program as Condition Report CR-ANO-1-2009-865. The performance deficiency was more than minor because it affected the procedure quality 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 Inspection Manual Chapter 0609, Significance Determination Process, Phase 1 Worksheet, this 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 functions would not be available. The finding was determined to have a crosscutting aspect in the area of human performance associated with work practices H.4(b), in that the licensee failed to define and effectively communicate expectations regarding procedural compliance and personnel followed procedures. Specifically, station planners failed to follow Procedure EN-WM-105 when developing work instructions for a reference level work package which resulted in an inadequate work package for the planned activities for the isophase blower |
