Right now, we think they're taking an appropriate approach. This is a plant that is operating safely and meeting our standards," he added.The plant is located about 80 miles south of Omaha, where snow melt and heavy rains have forced the waters of the Missouri River over its banks, although they have not flooded the plant and receded slightly on Sunday.Jaczko said he was not doing an official plant inspection. He was briefed by NRC resident inspectors -- the agency staff who work on-site every day -- plant officials and executives, said Mark Becker, a spokesman at the Nebraska Public Power District, the agency that runs the plant.The power plant sat about 4 feet above the river's level on Sunday. The river had surged over its banks near the plant and filled in low-lying land near the Cooper plant.Water levels there are down after upstream levees failed, Becker said, relieving worries that water will rise around the Brownville plant as it has at another nuclear plant north of Omaha in Fort Calhoun.Art Zaremba, director of nuclear safety at Cooper, backed the assessment."The plant is very safe right now, and we've taken a lot of steps to make sure it stays that way," Zaremba said.
