Title | Alert Declared Due To Loss Of Main Control Board Annunciator Panels |
Event Description | An Alert was declared at 13:19 CST for Unit 2 due to a loss of all main control board (MCB) annunciator capability.

The Alert was terminated at 13:39 CST. Unit 1 [was not affected by this event and] is currently Mode 1, 100%." Unit 2 is currently defueled.
The licensee notified the NRC Resident Inspector along with State, local, and other government agencies. The licensee will be issuing a press release. Notified NRR Jim Dyer. External notifications also included HHS (Miller). |
