| Title | Licensee-Identified Violation |
| Description | Technical Specification Table 3.3-1, functional Unit 20, requires the reactor trip system trip logic to be operable. Technical specification 3.0.3 requires that action be taken within one hour to place the unit in Hot Standby within the next six hours. Contrary to the above, for the period from July 14 2008, until October 11, 2008, reactor trip system logic for undervoltage protection was not operable, and action was not taken to shutdown the unit as required. When discovered on October 11, 2008, an investigation was initiated, the reactor protection trip logic circuitry was altered and relays were replaced to restore the system to an operable configuration. The issue was documented in the licensees corrective action program as Condition Report 2009-28058. This finding was of very low safety significance because redundant reactor protection features remained available to assure safety should an undervoltage condition occur |
