| Title | Licensee-Identified Violation |
| Description | Title 10 CFR Part 50, Appendix B, Criterion XI, Test Control, requires, in part, that a test program shall be established to assure that all testing required to demonstrate that structures, systems, and components will perform satisfactorily in service is identified and performed in accordance with written test procedures which incorporate the requirements and acceptance limits contained in applicable design documents. Test results shall be documented and evaluated to assure that test requirements have been satisfied. Contrary to these requirements, from April 16, 2009, through January 31, 2015, ANO identified that a test program had not been established to assure that all testing required to demonstrate that structures, systems, and components will perform satisfactorily in service was identified and performed in accordance with written test procedures which incorporated the requirements and acceptance limits contained in applicable design documents. Specifically, the failure to monitor the flow rate through the Unit 1 SW to SFP makeup line, which is subject to biofouling, to demonstrate this line would perform satisfactorily in service to meet the design flow rate. The 18 month surveillance flow test was not sufficient to monitor, predict and take actions to correct for the loss of flow caused by biofouling, consequently, line blockage occurred that resulted in the loss of the capability to provide full design makeup flow rates. ANO documented this violation in the CAP as CR-ANO-1-2014-01628. The team determined that this issue was of very low safety significance (Green) after reviewing IMC 0609, Attachment 0609.04, and Appendix A, Exhibit 3 Barrier Integrity Screening Questions. Specifically, the team answered no to each of the SFP questions in Exhibit 3. |
