Description | |
A reactor at the Beaver Valley Nuclear Power Station was shut down Tuesday morning in a rare forced outage caused by a malfunctioning generator. A spokesman for the Nuclear Regulatory Commission confirmed that Unit 2 was taken offline by plant operator FirstEnergy because of vibrations in the main generator. The vibrations resulted from parts in the main generator stator, a stationary part of the rotary system used in an electric generator, that had either broken or become loose, said Neil Sheehan of the NRC. “Remember that these machines rotate at 1,800 rpm and will have some wear from actual mechanical vibrations, as well as from repeated heating and cooling cycles,” he said. “The generators are large electrical components that are cooled by hydrogen.” The shutdown of the 846-megawatt reactor subtracted 0.2 percent from the nation’s electric grid, moving nationwide nuclear power production to 84 percent capacity, according to NRC data compiled by Bloomberg. As of Tuesday evening, the reactor remained offline, NRC data showed. The NRC’s resident inspectors for the Shippingport plant “will keep close watch on the company’s efforts to troubleshoot the vibration issue as well as any repairs that are made,” Sheehan said. Unit 2 is a pressurized water reactor, which means that steam created in the plant’s steam generators is piped to the turbine to spin it and, via the generator, converts that energy to electricity that is then sent out into the grid, officials said. Unit 2 came online in 1987. The plant’s other reactor, Unit 1, came online in 1976. Thanks to: http://familysurvivalprotocol.com |
