FORT CALHOUN, Neb. -- The hail storm that hit Blair last month caused roughly $5 million damage to the Fort Calhoun nuclear power plant. The June 3rd storm damaged homes and vehicles with baseball-sized hail and winds stronger than 90 mph. OPPD spokesman Jeff Hanson says the storm didn't disrupt the nuclear power plant's operations, but the hail did damage the roof of the administration building, broke some windows and also damaged rooftop air conditioners and other equipment. The storm also caused significant damage to utility vehicles that parked at the complex.
