[ RadSafe ] Ft. Calhoun

[Jeff Terry]

As a precaution, they started the backup diesel generators. They did not lose off-site power, but made the switch in case water got to close to the electrical switching gear. They are deciding whether or not to switch back to offsite power according to the NRC link in the last message. 

If all power from offsite is lost and the on-site backups fail, the coolant eventually stops circulating.
