Плазмохимический синтез и исследование наноразмерных сложных оксидных композиций, имитирующих плутоний-ториевое дисперсионное ядерное топливо

Abstract

This paper presents the results of experimental studies of the process of plasmachemical synthesis of fuel oxide compositions for plutonium-thorium dispersion nuclear fuel. The precursors were modeling waterorganic nitrate solutions having a lower calorific value of at least 8.4 MJ/kg and including an organic component (acetone) and mixed water nitrate solutions of a matrix metal (magnesium), as well as samarium, and cerium, having similar physicochemical properties with fissile metals (plutonium and thorium). There were determined the compositions and modes of processing modeling solutions that provide plasmachemical synthesis of nanosized complex oxide compositions in the air-plasma.
