| Title | Licensee-Identified Violation |
| Description | Title 10 of the Code of Federal Regulations, Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that activities affecting quality 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. Attachment 3 of Callaway Procedure APA-ZZ-01400, Appendix K, Tools for Event Prevention, is a procedure that affects quality. It states that workers shall identify conditions on a jobsite such as sensitive equipment in the work area, and continues on to state the worker needs to eliminate hazards, install appropriate barriers, or develop contingencies before proceeding with the task. Contrary to the above, on September 12, 2014, the licensee failed to accomplish an activity affecting quality in accordance with procedures
Specifically, maintenance technicians failed to follow Procedure APA-ZZ-01400, Appendix K, and identify that train A emergency diesel generator jacket water heater outlet relief valve was sensitive equipment in that it was a valve that could be accidentally repositioned if working in the area. As a result, they failed to protect the valve from inadvertent operation. During maintenance, the valve was bumped out of position during maintenance work, causing the jacket water system to slowly leak and rendered the diesel inoperable for approximately 25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> before being identified by operations personnel. Using NRC Inspection Manual 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, the finding was determined to be of very low safety significance because it did not affect the design of the system, did not result in a loss of system function, did not represent a loss of function of a single train for greater than its technical specifications allowed outage time, and did not cause the loss of function of one or more non-technical specification trains of equipment designated as high safety-significance. This violation was entered into the licensees corrective action program as Callaway Action Request 201406128. |
