The effect of uniform slurry settling on reactivity in one-region thorium breeder reactors of economic interest was investigated. The fuel considered was a mixed slurry of UO₂ and ThO₂ suspended in D₂O. It was found that when settling occurred, thermal reactors of possible economic interest (10 to 12 ft diameter containing 200 to 300 g Th/liter) became subcritical.
