MANUAL REACTOR SCRAM DUE TO LOSS OF FEEDWATER HEATING
At 2256 CDT on 6/10/17, Clinton operators manually scrammed the reactor from 99 percent power due to a loss of feedwater heating. The scram was uncomplicated and the plant is stable and in mode 3. All rods inserted and decay heat is being removed by the condenser. All offsite power is available. The cause of the loss of feedwater heating is under investigation.
The NRC Resident Inspector and the State of Illinois have been notified.
