Article

This work is devoted to the application of a numerical method of solving Boltzmann’s equation for modeling the behavior of radionuclides (Kr, Xe, Rb, Sr, Cs, Ba) in the cavity of the interelectrode gap of a multielement electricity generating channel. Modeling methods were developed and software system implemented in the course of this work. Calculations were performed for two structural arrangements: with uni- and bilateral extraction of radionuclides into the vacuum-cesium system. Data on the pressure and flow distributions were obtained. The krypton and xenon pressure near the collector as functions of their flow and the cesium gas pressure at the gap exits were determined computationally.
