Emissivity evaluation of gray gases for radiation calculations model was developed for the boiling and drying out accident analysis code FATE. The correlation equations for the gray gases emissivity depending on “temperature” and “pressure x gas thickness” were obtained using the absorption line spectrum calculation database HITRAN.
