Friday afternoon, the Wolf Creek nuclear power plant in Kansas shut down automatically following loss of offsite power due to a failure in the plant’s switch yard. The reactor’s Emergency Diesel Generators activated in response to the incident. All Wolf Creek reported this morning was that the loss of power was expected to last more than the fifteen minutes that triggers a Notice of Unusual Event. The reactor is still at zero per cent output this morning, according to today’s Reactor Status Report. No word yet on whether Wolf Creek is still operating on generator power today.
