A Nuclear Regulatory Commission spokesman told The Iowa Independent Friday that dry cask storage of spent nuclear fuel rods at two Nebraska facilities are not being protected from flood waters because the situation poses no public or environmental threat. Victor Dricks, an NRC Region 4 spokesman, said by phone Friday afternoon that the regulatory agency continues to closely monitor conditions along the Missouri River where floodwaters are rising at the Cooper and Fort Calhoun nuclear power stations. Flooding, brought on by heavy rainfall and snow melts in northern states, is expected to continue for several weeks.
