Federal inspectors plan to review how well a Nebraska nuclear power plant handled a water service safety problem blamed on a silt buildup from the Missouri River.
The river overwhelmed levees along its length last spring. The Nuclear Regulatory Commission said in a news release Thursday that the Cooper Nuclear Station near Brownville was operating Dec. 6 when employees detected that water wasn't flowing through a pipe connected to the plant.
Nebraska Public Power District soon determined that silt had built up and blocked the pipe outfall. The district had the silt removed within a week.
