Study of phosphate systems for high-level waste solidification. Part 2

This report represents a continuation of the systematic investigation of the system fission products + corrosion products + sodium in phosphate matrix to be used as the end product in high-level wastes solidification process. Data are included on properties of these solids prepared at various temperatures in the range 900 to 1200 degC, especially on their hydrolytic resistance. Data are given on crystallization ability, characteristics of crystalline phases and results of thermophysical measurements are presented. Orthogonal factorial analysis was used for the mathematical interpretation. (author)
