| Title | Failure to Properly Implement Steps Outlined in Technical Specification Surveillance Procedure |
| Description | A finding of very low safety significance and associated non-cited violation of Technical Specification 5.4.1., Procedures, was self-revealed on March 14, 2013, when an unexpected isolation of the reactor core isolation cooling (RCIC) system occurred as a result of the licensee s failure to properly implement the steps outlined in TS Surveillance Procedure LIS-RI-201, Unit 2 RCIC Steam Line High Flow Isolation Calibration. Specifically, during performance of the surveillance, a conditional step was inappropriately answered which led to bypassing the remaining sections in the applicable surveillance procedure for resetting the RCIC high steam flow isolation signal and resulted in the Unit 2 RCIC steam supply outboard isolation valve (2E51-F008) going shut upon closure of its associated breaker, 2AP71E-B4. The licensee s failure to properly implement the steps in the procedure was a performance deficiency that was determined to be more than minor, and thus a finding, because it was associated with the Mitigating Systems Cornerstone attribute of equipment performance and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The finding was determined to be of very low safety significance (Green). This finding has a cross-cutting aspect in the area of human performance, work practices, for failing to communicate human error prevention techniques, such as, performing the proper self and peer checks. Specifically, the licensee committed a human performance error by inappropriately performing a procedural step without performing the proper self and peer checks, which resulted in an isolation of the RCIC system. |
