CALCULATED CRITICAL MASS FOR SPHERES OF 233UO2-H2O MIXTURES FOR NUCLEAR CRITICALITY SAFETY EVALUATIONS

摘要

In the absence of experimental criticality data, calculations of critical masses of spheres, which contain 233U as metal or oxide-water mixtures and which are unreflected or reflected by H2O or 2 in. of lead, have been made at full density and at reduced density.
