DescriptionAEC-71-9136 THE REACTOR CONTAINMENT VESSEL FOR DIABLO CANYON'S UNIT 1 was brought ashore at a special barge landing site near Avile Beach, California, on September 17, 1970, after a barge-ship-barge trip had brought it from Chattanooga, Tennessee. Built by Combustion Engineering for the Pacific Gas & Electric Company, the 345-ton vessel was barged down the Tennessee, Ohio, and Mississippi Rivers to New Orleans where it was loaded aboard a ship. After passing through the Panama Canal, the reactor component was again trans-shipped at San Francisco for a barge trip back down the coast to Avil Beach. For the last 7 miles, from the beach to the Diablo Canyon site, the vessel was aboard a 1922-wheeled trailer. The Westinghouse-built, 1,060-Mwe. pressurized water reactor is scheduled for 1972 operation; a twin unit, for which the PG&E received an AEC construction permit in December, has a planned 1973 operational date.
