July 17, 1955, was the first time electricity generated by a U.S. nuclear power plant flowed into a utility grid. The experiment required Utah Power & Light to disconnect itself from the power lines to the 1,200 residents of Arco, Idaho, and plug in the Argonne National Laboratory experimental boiler water reactor, BORAX-III. The plant produced merely 2 megawatts for more than an hour, as planned, after which linemen reconnected the town’s grid to the utility. Since then, the U.S. nuclear industry has demonstrated excellence in operations, but more than 50 years after that first nuclear power supply, it is lagging far behind even developing nations in new construction.
