FUEL FOR FAST NEUTRON POWER REACTOR WITH CORE IN FORM OF MOLTEN SALT FOR CONVERTING THORIUM-232 TO URANIUM-233

摘要

FIELD: physics.;SUBSTANCE: fuel composition contains (wt %): potassium chloride - 24 + magnesium chloride -16 + thorium tetrachloride - 30 + plutonium trichloride - 30 and at operating temperature of 550-560°C has density of 2.53 g/cm. As an example, calculation data for a 400 MW(el.) nuclear reactor with core dimensions (D=H=180 cm) are given: core volume=4578120 cm.3, mass of salt filler=10772 kg. Uranium-233 conversion ratios can be KB_AZ=0.3, and when using a blanket region made from thorium dioxide, overall KB can reach 1.2.;EFFECT: enabling switching of the nuclear reactor to a mode of using uranium-233, obtained by converting thorium-232, with periodic filling of the core with thorium.
