This resulted in the energizing of pressurizer backup heaters, loss of automatic operations of the main feedwater pump lube oil temperature and loss of the first stage pressure input, requiring operator action to regain control of systems. The performance deficiency was determined to be more than minor because it was associated with the configuration control attribute of the Initiating Events Cornerstone and affected the objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during power operations, and is therefore a finding. Using Inspection Manual Chapter 0609, Phase 1 Worksheets, the finding was determined to be of very low safety significance because the finding did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not have been available. It was determined that the finding had 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 complianc |
