The Hallam plant was a sodium cooled, graphite moderated reactor with a 256 MWt output (Allen, 1977). It started up in 1962 and was permanently shut down in 1964. Atomics International, a subsidiary of Rockwell Aerospace, designed the core and coolant system for this plant. The aggressive effects of the sodium coolant on several alloys were not fully appreciated when the reactor started up. As a result, corrosion on the stainless steel cladding of individual fuel elements led to this plant s shutdown after just over 1 year of operation (Anon., 1972). 

More recent experiments with the Ixinetic Experiment for Water Boilers (KEWB-1), operated by Atomics International for the U. S. Atomic Energy Commission [9], have verified the self-controlling features of a solution-type reactor. It was found that automatic shutdown due to the temperature increase and formation of gas bubbles in the reactor fuel solution occurs under all abnormal operating conditions te.stcd.

The first solution-type research reactor for industrial use went into operation in June 1956. The general features of this reactor, which Atomics International built for the Armour Re.scarch Foundation at the Illinois Institute of Technology, Chicago, Illinois, are shown in Fig. 7-2. 

This is the most extensive discussion of hquid-metal fuel reactor development yet published in the United States. Emphasis has been placed on the Liquid Aletal Fuel Reactor being developed by Brookhaven National Laboratory and Babcock Wilcox Co. because it is the most advanced project. Work on various phases of liquid-metal fuel reactors is being carried out by Los Alamos Scientific Laboratory, Raytheon Manufacturing Co., Argonne National Laboratory, Ames Laboratory, and Atomics International. The editor would like to have given more coverage to work at the last three locations but was unable to because time was lacking. 

The results of design studies, calculations, and experiments for the reactor types selected for investigation in the post-Wodd War II period were collected in the multivolume proceedings of several international conferences at Geneva (24). The U.S. Atomic Energy Commission (AEG) sponsored the pubhcation of individual books between 1958 and 1964 describing the status of several reactor types (9,18,33—36).
