Abstract

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.
