| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.4.1, Procedures, required that written procedures be established and implemented covering activities specified in Appendix A, Typical Procedures for Pressurized Water Reactors, of Regulatory Guide 1.33, Quality Assurance Program Requirements (Operation), February 1978. Regulatory Guide 1.33, Appendix A, Section 9.a, required procedures for performance of maintenance. Contrary to the above, on September 13, 2007, work instruction W219154 for the rebuild of the turbine-driven auxiliary feedwater pump trip throttle valve was not followed. Specifically, the beveled thrust washer within the valves split coupling was installed bevel side up contrary to the work instructions. Consultation with the vendor confirmed that the installation error would add significant friction to the operation of the valve. This finding was entered in the licensees corrective action program as Callaway Action Request 200904216. This finding is greater than minor because it was associated with the Mitigating Systems Cornerstone attribute of procedural quality and it affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Manual Chapter 0609.04, Phase 1 Initial Screening and Characterization of Findings, the issue screened as very low safety significance because it was not a design or qualification deficiency that resulted in a loss of operability or functionality, did not create a loss of system safety function of a single train for greater than the technical specification allowed outage time and did not affect seismic, flooding, or severe weather initiating events |
