| Title | Licensee-Identified Violation |
| Description | Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that instructions, procedures, or drawings include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished. Contrary to this requirement, ANO identified that in 2010, maintenance work orders installing safety-related circuit breakers in motor control centers D-15 and D-25 did not have appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished. Specifically, Engineering Change 5832 was completed to replace seven safety-related existing and obsolete Gould circuit breakers inside safety-related motor control centers D-15 and D-25 with Siemens ED6 series molded case circuit breakers, using work orders 122821 and 122823. Subsequent review of these work orders confirmed that the installation instructions properly included specific torque values for the breaker mounting hardware, but the specified torque values were not recorded in the work orders, and the torqueing operations were not verified by quality control as required by procedures. ANO documented this issue in the CAP as CR-ANO-1-2015-02230. The team determined that this issue was of very low safety significance (Green) after reviewing IMC 0609, Attachment 0609.04, Appendix A, Exhibit 2 Mitigating Systems Screening Questions. Specifically, the team answered no to each of the questions in Exhibit 2. |
