Flood berm collapses at Nebraska’s Fort Calhoun nuke plant; facility shut down since April
“FORT CALHOUN, Neb. — A berm holding back floodwater at the Fort Calhoun Nuclear Station has collapsed.
The U.S. Nuclear Regulatory Commission says it’s monitoring the Missouri River flooding at the plant, which has been shut down since early April for refueling.
The 2,000-foot berm collapsed about 1:30 a.m. Sunday, allowing the swollen river to surround two buildings at the plant. The NRC says those buildings are designed to handle flooding up to 1014 feet above sea level. The river is at 1006.3 feet and isn’t forecast to exceed 1008 feet.
The NRC says its inspectors were at the plant when the berm failed and have confirmed that the flooding has had no impact on the reactor shutdown cooling or the spent fuel pool cooling.
NRC Chairman Gregory Jaczko will visit the plant Monday.”

According to the NRC’s Burnell, the added flood barriers will protect the plant even if the river rises beyond where it is currently projected to go.
