Description of the Heat Removal System

    Without heat removal the anticipated pumping power of 1000 hp for the primary salt pump would raise the temperature of the approximately 100 ft3 of circulating salt nearly 6 °F per minute. A study was made of an open cycle system designed to remove 3-82 X 10^s Btu/hr, that is, to accommodate 1500 hp pumping power.
    Several different heat removal systems were investigated to provide a tolerable noise level, reasonable physical size, safety, economical and simple construction and operation, and minimum maintenance. Systems investigated included (l) thermal convection salt-to-air radiator, (2) forced circulation salt-to-air radiator, (3) salt-to-steam heat exchanger
