OMAHA, Neb. (AP) – The Cooper Nuclear Station in southeast Nebraska is operating as normal despite flooding along the Missouri River. Nebraska Public Power District spokesman Mark Becker says workers continue to monitor flood barricades and the protections are holding up well.

The Columbus-based utility on Sunday issued a “notification of unusual event” for the plant. Such a declaration is required when the Missouri River rises to 42.5 feet, or 899 feet above sea level. Cooper is at 903 feet elevation, and the river would have to climb to 902 feet before officials would shutter the plant.

Becker says the river is forecast to crest there at a little over 900 feet. At such a level, officials would need to barricade internal doorways at the plant to protect equipment.
