| Title | Licensee-Identified Violation |
| Description | A licensee-identified violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, associated with the SI pump oiler modifications performed in 1995, was identified. The details of this issue are discussed in section 4OA3.2 On February 27, 2011, during testing of the Unit 2, SI Train A, an operator took initiative to inspect SI Train B. The operator found that the oiler for SI Pump B had rotated, resulting in a loss of lubricating oil to the pump inboard bearing. As a result of this condition, the licensee declared Train B inoperable. With Train A inoperable for testing, and Train B inoperable for the oiler deficiency, the licensee entered TS 3.0.3. The licensee took immediate corrective actions to restore Train B to service by refilling and reinstalling the oiler. Subsequently, the licensee performed a root cause evaluation for the issue and determined that the oiler was modified in 1995 and that the modification introduced a latent design/configuration flaw that rendered the oilers susceptible to inadvertent bumping events. The licensee instituted corrective actions to modify the design to make to oiler less susceptible to becoming inadvertently dislodged. The inspectors considered this issue as a licensee-identified violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, because the issue was identified as the result of an operator performing a deliberate and focused observation of the SI system, and because the issue was not discovered as a result of the condition being self-revealing. Documents reviewed are listed in the Attachment to this report. |
