Survey of the Static Nuclear Characteristics of Small, One-Region Slurry Reactors
- Oak Ridge National Laboratory (ORNL), Oak Ridge, TN (United States)
Survey calculations were made of the criticality characteristics of some small one-region thorium-oxide slurry reactors. Fuels considered were U235 and U233, and both D2O and H2O moderated systems were studied. Critical fuel concentrations were calculated as functions of size, temperature, and thorium concentration. For 4- to 5 1/2-ft diameter spherical ThO2-D2O reactors fueled with U235, the minima in the U235/Th ratio curves occurred at about 200 gm Th/liter. The critical ratio obtained for a 5-ft diameter bare D2O reactor at 280°C increased from 0.08 to 0.10 g U235/g Th as a thorium concentration was increased from 200 to 400 gms per liter.
