Thermodynamic simulation of the oxidation of radioactive graphite in the Na 2 CO 3 –K 2 CO 3 –NiO and Na 2 CO 3 –K 2 CO 3 –CuO melts

The oxidation of radioactive graphite in the Na2CO3–K2CO3–NiO and Na2CO3–K2CO3–CuO melts in the temperature range 373–3273 K is subjected to a thermodynamic simulation. The behavior of radionuclides is studied and the equilibrium constants of the reactions occurring in these systems are calculated.
