| Title | Licensee-Identified Violation |
| Description | Title 10 CFR Part 50.65, Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants, Section (a)(4), requires, in part, that before performing maintenance activities, the licensee shall assess and manage the increase in risk that may result from the proposed maintenance activities. Contrary to these requirements, on July 8, 2015, ANO identified that they failed to assess and manage the increase in risk that may result from the proposed maintenance activities. Specifically, ANO failed to assess and manage the risk associated with removing and cleaning the Unit 2 SW system pre-screens for maintenance. ANO documented this violation in the CAP as CR-ANO-2-2015-01865. Additionally, ANO added guidance to procedure COPD-024 to address this issue. The team determined that this issue was of very low safety significance (Green) after reviewing IMC 0609 Attachment 0609.04, and Appendix K, Maintenance Risk Assessment and Risk Management Significance Determination Process, dated May 19, 2005. Specifically, the team determined the incremental core damage probability deficit was not greater than 1E-6. |
