| Title | Operator Performed an Incorrect Response to an Unexpected Alarm in the Control Room |
| Description | On January 13, 2009, a Finding with no violation of regulatory requirements was self-revealed when an operator performed an incorrect response to an unexpected alarm in the control room that resulted in a reactor building ventilation isolation and a standby gas treatment system actuation. This action required entry into TS 3.6.4.1 Limiting Condition of Operation, Action A for reactor building low differential pressure. The finding was more than minor because it impacted the structures, systems, and components attribute of the Barrier Integrity Cornerstone objective. The finding was of very low safety significance because it impacted the reactor building differential pressure for a time period of less than one hour. The finding was placed into the licensees CAP as IR 866445. As an immediate corrective action, the individual was temporarily removed from licensed shift duties and no manipulation of any equipment in the plant or the control room was allowed without a peer check until January 18, 2009. The inspectors also concluded that this finding affected the cross-cutting issue of Human Performance (Personnel) because the operator failed to utilize human performance error prevention techniques, (H.4(a)) |
