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.

OMAHA, Neb. (AP) —
A berm holding back floodwater at a Nebraska nuclear power plant has collapsed.
The U.S. Nuclear Regulatory Commission says the 2,000-foot berm at the Fort Calhoun Nuclear Station collapsed about 1:30 a.m. Sunday.
There is no danger. The plant has been shut down since early April for refueling, and the commission says there's no water inside.
Also, the Missouri River isn't expected to rise past the flood level the plant was designed to handle.

NRC spokesman Victor Dricks says the plant remains safe. NRC Chairman Gregory Jaczko will visit the plant Monday.

"The water level at Ft. Calhoun nuclear plant reached a height of nearly 1,007 feet above sea level at the plant yesterday."
"The NRC responded in its October 2010 letter that once flooding reached 1,004 feet, water would have entered the plant and the ability of emergency workers to move around the site would “significantly degrade.”
"At 1,010 feet, water would begin to enter the auxiliary building, “shorting power and submerging pumps. The plant could then experience a station blackout with core damage estimated within 15 to 18 hours,” under a worst-case scenario, the NRC said. "
The berm's collapse didn't affect the reactor shutdown cooling or the spent fuel pool cooling, but the power supply was cut after water surrounded the main electrical transformers, the NRC said. Emergency generators powered the plant Sunday while workers tried to restore power.
