Zusammenfassung:Title screen
The central problems of using ceramic nuclear fuel fabricated from uranium dioxide enriched in uranium-235 are low thermal conductivity, high disposal costs, and limited natural reserves of uranium-235. A potential direction for the further development of nuclear power in Russia is the use of mixed uranium-plutonium dispersion fuel consisting of fissile materials (uranium and plutonium dioxides) uniformly distributed in a matrix of metal oxides, which have a high thermal conductivity and a low neutron absorption cross section. The methods used to obtain complex oxide compositions (sol-gel, separate preparation, mechanical mixing, and others) are multi-stage, do not provide a uniform distribution of phases, and are characterized by high energy and labor costs. This article proposes a plasma-chemical method of synthesizing nanosized complex oxide compositions in an air-plasma flow from dispersed water-organic nitrate solutions, which provides a significant reduction in energy consumption, a uniform distribution of phases, and the required phase composition.
