Abstract

By use of the Los Alamos transport code, a parametric set of criticality conditions for one-dimensional geometries of light water solutions of the fissionable materials U/sup 233/, U/sup 235/, and Pu/sup 239/ wae determined. Minimum critical dimensions for slabs and cylinders and critical radius, mass, and volume for spheres as a function of solution concentrations (kg/l) and H/X atomic ratio are shown for bare and light water reflected solutions. Results of experimental studies for critical dimensions are given to support the study. (auth)
