| description = The inspectors identified a finding of very low safety significance (Green) for the failure to incorporate human performance standards when developing work package instructions in accordance with MAAA716010,Maintenance Planning, Revision 23. Specifically, the licensee did not assure the cable vault dewatering system installation and maintenance work order (WO) included the appropriate details to troubleshoot and install the cable vault sump pumps and float switches. This resulted in installation of the equipment in a manner that prevented detection and removal of water from the cable vaults, allowing cables to remain submerged undetected. The licensee entered this issue into their CAP as AR 02668245. The corrective actions performed by the licensee included placing the sump pumps in the right location and adjusting the float switches to ensure the indications would alert operators when the vaults needed to be pumped. The inspectors determined that the failure to incorporate human performance standards when developing work package instructions in accordance with MAAA716010, Maintenance Planning, Revision 23, was a performance deficiency. The performance deficiency was determined to be more than minor because if left uncorrected the performance had the potential to lead to a more significant safety concern. Specifically, by not appropriately installing the sump pumps and float switches, the cables would be allowed to remain submerged undetected. The finding was screened against the Mitigating Systems cornerstone and determined to be of very low safety significance (Green) because the inspectors answer Yes to the question does the SSC maintain its operability or functionality?. This finding has a cross-cutting aspect in the area of human performance in the aspect of conservative bias, where individuals use decision making practices that emphasize prudent choices over those that are simply allowable. Specifically, because the licensee classified the cable vault dewatering system as a maintenance tool, they decided it was not necessary to include specific instructions within the WOs related to ensure the troubleshooting and re-installation activities were performed appropriately.
