10 CFR Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, and drawings. On December, 27, 2007, operations Component Cooling Water (
CCW) system valve, TCV-14-4B failed its quarterly
stroke time surveillance. The cause of this failure was attributed to the installation of an o-ring not designed for the application. This installation of an unapproved o-ring was a deviation from the requirements of site procedure QI-8-PR/PSL-1. This violation is of very low safety significance because it did not result in actual loss safety function for the B Train ICW for greater than its Technical Specification allowed outage time.
