Distribution and Elution of Fission Products upon ThO₂-UO₃ Slurry at Simulated Reactor Conditions

The adsorption of simulated fission products on slurries of ThO₂-UO₃ mixtures has been studied. Experiments were performed using tracer techniques employing slurries which had been previously pumped in order that the condition of the slurry as well as concentration of the fission products, temperature, and pressure might simulate reactor conditions. Results of some preliminary experiments designed to remove fission products by the use of eluting agents are also reported.
