| Title | Failure to Develop Adequate Post Modification Testing for the Alternate Seal Injection System |
| Description | An NRC-identified FIN was identified for the failure of the licensee to accomplish station procedures for development, review, and performance of adequate post modification testing of the alternate seal injection (ASI) system. The problem is in the licensees CAP as CR 13-00642. The inspectors determined that the failure to accomplish station procedures to develop, review and implement adequate post modification testing in accordance with station procedures was a PD, and was within the licensees ability to foresee and correct based on their existing knowledge of ASI designs at other plants. The inspectors reviewed IMC 0612 and determined the PD is more than minor and therefore a finding because if left uncorrected it would have the potential to result in a more significant safety event. Specifically, loss of the ASI system would lead to a reactor coolant pump seal loss of coolant accident during those events involving a loss of normal seal cooling such as a station blackout or fire. The inspectors reviewed IMC 0609, Attachment 4 and Appendix A, for the significance determination and determined the finding was of very low safety significance, or Green, because it did not involve a design deficiency and was not an actual loss of function. The inspectors reviewed IMC 0310 for cross-cutting aspects and determined the cause of the finding involved the area of human resources and the aspect of H.11, challenge the unknown, because the licensee did not identify the appropriate post modification testing when using a, first-for-the-station, ASI design. |
