A licensee-identified finding of very low safety significance (Green) and associated
NCV of
10 CFR 50, Appendix B, Criterion V, Procedures, was identified on August 9, 2012. Station personnel performing a procedure review and walk-down identified that the jumpers in the staged jumper packet for QCOP 0250-02 had not been updated after installation of banana jacks on the installation terminals. Failure to update the jumpers after the modification was installed is a performance deficiency. The individual entered the issue into the
CAP as
IR 1386431. The finding is more than minor because it adversely affected the equipment reliability attribute of the
Mitigating Systems Cornerstone objective to ensure the availability, reliability, and capability of systems responding to
initiating events to prevent undesirable consequences (i.e., core damage). The extent of condition walk-down for this issue identified six other jumper packets that contained the wrong number or type of jumpers, the wrong type of relay blocks, or the wrong tools. Title
10 CFR 50, Appendix B, Criterion V, Procedures, requires in part that activities affecting quality shall be prescribed by procedures of a type appropriate to the circumstances and shall be accomplished in accordance with those procedures. Contrary to the above, jumpers supporting emergency procedure required actions were not updated after plant modifications were implemented. While inspectors deemed that the procedural action could probably have been accomplished using other materials available to the control room personnel, the wrong staged material could result in unnecessary delays or human performance errors that would impact emergency actions and result in undesirable consequences. As immediate corrective actions for this condition, the appropriate jumpers and relay blocks were placed in the staged packets.
