RICHLAND, Wash. (AP) — A nuclear power plant in Washington state was shut down over the weekend for a planned 40-day refueling outage, welcoming about 1,400 new temporary jobs to help staff the outage. The Tri-City Herald reported that the Columbia Generating Station near Richland was disconnected on Saturday so workers can replace about a third of the fuel in the reactor’s core. The temporary workers will assist about 1,000 permanent employees at Energy Northwest, the public utility company that operates the generating station. The plant is expected to supply power again in June.
