A new approach to modeling fissile solution densities is developed and applied to arbitrary solutions of UO22+, Th4+, Pu4+, H+, and NO3- in water. The model is based on the semiempirical method of Pitzer for describing electrolyte solution thermodynamics. This new density model has been included in the recent release of the SCALE 5 code system as the default for criticality calculations of fissile solutions.
