For the record: Ft Calhoun

-■Virtually every article about the flooding mentions that the Fort Calhoun plant was shut down on April 9. On May 27, the Omaha World-Herald reported, "The Omaha Public Power District said its nuclear plant at Fort Calhoun, which is shut down for maintenance, is safe from flooding." The implication is that being shut down makes a plant safe. But as the ongoing crisis in Fukushima demonstrates, nuclear fuel remains hot long after a reactor is shut down. When Fort Calhoun is shut down for maintenance and refueling, only one-third of the fuel in the reactor core is removed. Besides the hot fuel remaining in the core, there is even more fuel stored in the spent-fuel pool, which is not shut down. According to a May 2011 report PDF by Robert Alvarez at the Institute for Policy Studies, there are an estimated 1,054 assemblies of spent fuel, weighing 379 tons, at Fort Calhoun. The oldest of these assemblies are in dry-cask storage, which does not require any water or electricity for cooling. Like the dry casks at Fukushima, which survived the tsunami unscathed, the Fort Calhoun casks do not appear to be in any danger from flooding.
