PLUTONIUM SIMULATOR AT BURNING Russian patent published in 2003 - IPC

FIELD: investigation of processes of burning and distribution in atmosphere radioactive materials at emergency, namely almost complete simulation of process of burning and propagating plutonium during fire. SUBSTANCE: invention is realized due to using alloy containing (mass%): uranium, 88.2; ferrum, 11.8 for simulating process of plutonium burning. Such alloy allows to predict after-emergency conditions and to evaluate degree of environment contamination as melting temperature of plutonium is 640 C and melting temperature of alloy according to invention is 725 C; density of liquid plutonium is equal to 16.64 g/cub.cm and density of simulating alloy is equal to 15.1 g/cub. cm; heat quantity for generating combustion product of PuO₂ is equal to 1059 kJ/mol and that of combustion product of UO₂ is equal to 1086 kJ/mol. EFFECT: possibility for satisfactory predicting of after-emergency conditions and evaluating degree of environment contamination due to simulating characteristics of burning and aerosol formation, physico-chemical properties of plutonium. 1 tbl
