The world’s oldest operating nuclear reactor, the Graphite Reactor at Oak Ridge National Laboratory, was shut down last month after twenty years of continuous operation. Advancing technology has provided more modern means for performing its functions. In the two decades that it has functioned, the reactor has operated about 90 percent of the time, with shutdowns for routine maintenance accounting for the 10 percent time out.
