THE EOF IS CONSIDERED UNAVAILABLE DUE TO PARTIAL LOSS OF POWER.
A partial loss of electrical power to the Emergency Operations Facility (EOF) occurred at 0212 CST. The partial loss of power resulted from opening a circuit breaker that appeared to be tripped. The failed circuit feeds lighting in the EOF as well as various other support loads. Based on the partial loss of electrical power, the EOF is being considered unavailable. Callout of electrical support is in progress for troubleshooting and repair.
The NRC Resident Inspector will be informed.
