Title | Licensee-Identified Violation |
Description | TS 5.4.1(A) requires that written procedures recommended by Appendix A of RG 1.33, Revision 2, be established, implemented and maintained by the licensee. Section 1.c of RG 1.33, Appendix A, specifies the requirement for procedures that control equipment clearance and safety tagging, and the licensee implements this requirement with procedure OP-AA-109-101, Clearance and Tagging. On February 11, 2008, operations personnel conducting a plant inspection in the Unit 1 FW heater bay discovered DEHC system valve 1EH067 in the full open position. Contrary to the requirements contained in OP-AA-109-101, this valve was tagged with a clearance order Danger Do Not Operate card and should have been in the closed position. The objective of the Initiating Events Cornerstone of Reactor Safety is to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. In accordance with NRC IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening, the inspectors determined that the violation was of more than minor significance in that it had a direct impact on this cornerstone objective, one of the key attributes of which is equipment configuration control. The violation was further determined to be of very low safety significance because at the time of the event the entire DEHC system was completely shutdown and removed from service for extensive refueling outage work, and no hydraulic fluid or hydraulically-controlled valve movement could have occurred as a result of 1EH067 being out of its intended position. The licensee briefed all craft workers during their next pre-shift briefings on this incident, and entered the issue into their CAP as IR 734294. Additional corrective actions by the licensee included a CAP human performance investigation, which determined that the mispositioning of this valve was apparently the result of unintentional casual contact by a member of the station staff or contract workforce |
