Title | Licensee-Identified Violation |
Description | Title 10 of the Code of Federal Regulations Part 50, Appendix B, Criterion V, Procedures, requires, in part, that 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, or drawings. On January 31, 2011, a licensee immediate operability evaluation failed to consider the potential effect of voiding discovered in the train A safety injection accumulator\'s fill line. On May 18, 2011, the licensee monthly void check surveillance, OSP-SA-00003, discovered the safety injection pump discharge header high point vent had more than normal voiding. An extent of condition check revealed that upstream of the high point vent the amount of voiding exceeded the licensees operability acceptance criteria. The licensees initial operability reviews failed to consider the accumulator fill line voiding as possibly affecting train A safety injection header operability per licensee Procedure APA-ZZ-00500, Appendix 1, Step 4.1.1. Initial corrective action was increased void monitoring and venting frequencies and manual isolation of the accumulator fill line from the pump discharge header. This finding was entered in the licensees corrective action program as Callaway Action Requests 201100850 and 201104102. This finding was of very low safety significance since it did not represent actual loss of safety function of a single train for greater than its Technical Specification allowed outage time, did not represent an actual loss of safety function and did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. |
