Two Nebraska Nukes in Unplanned Shutdowns
LCG, Oct. 16, 2000Two nuclear power plants in Nebraska shut down Saturday taking 1,300 megawatts of generation with them, according to the Nuclear Regulatory Commission daily plant status report.The 800 megawatt Cooper Nuclear Station in Brownville, Neb., tripped off line at 3:40 a.m. on Saturday when its main generator shut down for unknown reasons. The plant's owners, the Nebraska Public Power District, said the facility would be placed in cold shutdown while operators figure out what went wrong with the dynamo.Operators at Cooper said that nobody was working on the generator at the time of the shutdown and that all automatic shutdown and safety systems operated as designed.Also on Saturday, operators of the 500 megawatt Fort Calhoun nuclear plant owned by the Omaha Public Power District manually shut down their facility because of apparent degradation of a reactor coolant pump seal.Officials said there was no leakage at the seal and the plant was placed in cold shutdown so the faulty seal could be replaced. The event was classified as an unplanned maintenance outage.
