Plasmachemical synthesis and the assessment of the thermal conductivity of fuel compounds “UO2–MgO”

Abstract

The process of plasma-chemical synthesis from water-organic nitrate solutions of uranium and magnesium of fuel compositions including a matrix of magnesium oxide with a high thermal conductivity and low neutron absorption is investigated. The compositions of the solutions, including acetone (ethanol), as well as the regimes that providing the direct synthesis of "UO2-MgO" fuel compositions of different concentrations in air plasma are determined. The calculation of their thermal conductivity and comparison with experimental data are presented.
