A difficult technical problem of importance in processing reactor fuels involves criticality of uranium rods in uranium solution (problem of uranium dissolution). The material buckling for such a mixture is difficult to evaluate by standard methods. MONTE CARLO techniques were used to evaluate the material bucklings for 3 wt% enriched uranium water lattices with various uranium concentrations in the moderator. The maximum material buckling that may be obtained under optimum geometry conditions was calculated to occur with uranium absent from the moderator. These results apply to solid rods only since tubular fuel elements were not considered.
