The additional plant, the Cooper Nuclear Station, sits on higher floor,Ralph Lauren Polo Shirts, and the plant's landlords say they propose to continue operating.
The flooding near the plants has heaved comparisons to the Fukushima nuclear plant in Japan, where an earthquake and tsunami in March marred and swamped the facility, knocked out electricity and resulted in serious problems keeping the plant's nuclear oil cool. That led to meltdowns and radiation releases.
But nuclear regulators and plant officials have said such cares are out of location.
"There's no likelihood of a Fukushima-like incident here," said Tim Nellenbach, director of the Fort Calhoun plant.
Elsewhere, up to 6 inches of rain that fell in parts of the Midwest on Sunday exacerbated problems.
