The Fort Calhoun nuclear power plant reported to the NRC today that it has lost communications with 21 of its 101 emergency sirens. The siren problems mean that two Iowa counties would not be alerted if there were a problem at the Nebraska nuke.
Unfortunately, attempts to reactivate the faulty sirens will require a complete reboot of Forth Calhoun’s warning system, which will cause more outages. According to the Event Report: “During the reboot, sirens in Washington County, Nebraska, will also lose communications and therefore will not be functional.”
Fort Calhoun says that it will institute compensatory measures in the event of an emergency, although the report is a bit vague as to how this will be accomplished. I envision a town crier with a bell, shouting: “Run for your lives!”
It’s kind of a moot point, since the Fort Calhoun nuclear power plant hasn’t been up and running on a regular basis since last April, when floods shut down the facility.
