The development of nuclear power in the future is tied to the development of fast reactors, including homogeneous reactors. The present paper proposes a new design for a homogeneous fast nuclear reactor (Fig. 1). A suspension consisting of uranium dioxide in the form of fine solid powder in a metallic alloy with the composition 52.5% Bi, 32% Pb, and 15.5% Sn with melting temperature 96℃ is proposed as the fuel. The density of this liquid is 10.2 g/cm~3, which is almost identical to the density of uranium dioxide 10.96 g/cm~3. This is important because settling, separation, and accumulation of powder decrease. Analysis of the change in the density of the medium and the powdered fuel as a function of the temperature shows that within the indicated temperature limits no strong difference in the density of the medium (Bi + Pb + Sn) and the fuel in the form of powder is observed (Fig. 2). This shows that the fuel and the medium should be compatible within the indicated temperature range. However, all preliminary calculations must be checked experimentally.
