THERMODYNAMIC MODELING OF RADIONUCLIDE BEHAVIOR DURING HEATING (BURNING) OF RADIOACTIVE GRAPHITE IN VAPOURS OF WATER

Radionuclides behavior at combustion of radioactive graphite in water vapors is examined by thermodynamic model analysis. It is determined that radioactive chlorine is present in the form of both HCl vapor and Cl atoms; radioactive americium — in the form of Am vapor; radioactive carbon — in the form of both CO vapor and CO2 vapor; radioactive nickel — in the form of Ni atoms and NiOH, NiO2H2, NiH vapors; radioactive uranium — in the form of UO3 and UO2 vapors; radioactive plutonium — in the form of PuO2 and PuO vapors; radioactive beryllium — in the form of Be(OH)2 and BeOH vapors; radioactive calcium — in the form of Ca(OH)2, CaOH vapors, and Ca atoms, and calcium oxide; radioactive strontium — in the form of Sr(OH)2, SrOH vapors, and strontium oxide, and Sr atoms; radioactive cesium — in the form of both Cs vapor and CsOH vapor.
