The shutdown happened Friday afternoon. Wolf Creek officials say the plant’s two emergency diesel generators automatically started, supplying power to all safety-related equipment.
Plant officials declared a “notification of unusual event,” which is the lowest of 4 emergency classifications defined by the Nuclear Regulatory Commission.
Wolf Creek is owned by Kansas City Power & Light Co., Topeka-based Westar Energy and the Kansas Electric Power Cooperative. During a shutdown, the companies rely on other generating plants they own or buy electricity from other utilities.
