THERMODYNAMIC MODELING OF RADIONUCLIDE BEHAVIOR DURING HEATING (BURNING) OF RADIOACTIVE GRAPHITE IN THE CARBON DIOXIDE ATMOSPHERE

Thermodynamic modeling method was used to study the behavior of radionuclides during the combustion of radioactive graphite in the atmosphere of carbon dioxide. It has been established that radioactive carbon is present in the form of vapor, CO and CO2; radioactive uranium in the form of vapor UO2, UO3, ionized UO2  , UO3 and condensed U3O5; radioactive chlorine in the form of vapor Cl, CaCl, CaCl2 and condensed CaCl2; radioactive calcium as vaporous Ca, CaO, CaCl, CaCl2, ionised Ca+, CaO+ and condensed CaO, CaCl2, CaCO3; radioactive nickel in the form of vapor Ni, NiO, NiCl, NiCl2 and condensed Ni3C, NiCO3, NiO, NiCl2; radioactive cesium vapor as Cs, CsCl, Cs and ionized condensed CsCl; radioactive plutonium in the form of vapor PuO, PuO2, ionized PuO+ and condensed PuO2; radioactive beryllium in the form of vapor Be, BeO, Be2O, Be2O2, Be3O3, Be4O4, BeCl, BeCl2, ionized Be+ and condensed BeO, BeCO3; radioactive americium in the form of vapor and condensed Am, AmO2, Am2O3; radioactive strontium in the form of vapor Sr, SrO, SrCl, SrCl2, ionized Sr+, SrO+, SrCl+ and condensed SrO, SrCl2, SrCO3; radioactive europium in the form of vapor Eu, EuO, EuCl3, ionized Eu+ and condensed EuO, EuOCl, EuCl2, Eu2O3.
