| Title | Licensee-Identified Violation |
| Description | Technical Specification 3.0.4 requires, in part, that entry into a mode or other specified condition in the applicability shall only be made when the associated actions to be entered permit continued operation for an unlimited period of time, or after performance of a risk assessment addressing inoperable systems, or when specifically allowed by the specification. Contrary to the above, in April 2010 and November 2011, Unit 2 transitioned from Mode 4 to Mode 3 without all required equipment being operable, without performing a risk assessment, and when not allowed by the specification. Specifically, the turbine trip signal from the reactor trip breakers, the turbine trip signal from the reactor trip signal, and the turbine trip signal from a steam generator HI-HI level were all inoperable due to a jumper being installed for testing when the plant transitioned from Mode 4 to Mode 3. The inspectors used Manual Chapter 0609, Appendix A since the finding was identified after residual heat removal was secured, and determined that the finding was of very low safety significance because the finding did not contribute to both the likelihood of a reactor trip and the loss of mitigation equipment. The licensee entered this issue into the corrective action program as Condition Report 11-27377. |
