IONIZATION EQUILIBRIUM AND COMPOSITION OF LI-H-U PLASMA

Abstract

In this paper composition of a non-ideal lithium-hydrogen-uranium plasma was studied using the Saha equation. The results obtained in this paper can be used both in theoretical calculations and in the implementation of various experimental projects related to non-ideal plasma, in particular, for studying the thermodynamic properties of nuclear fuel detected in gaseous plasma form in nuclear jet engines. The degree of ionization of lithium, hydrogen, and uranium atoms was determined as the ratio of the number of free electrons to the total number of nuclei in the plasma. The composition of the ionized plasma was calculated in the framework of the system of the chemical model of plasma. A system of nonlinear Saha equations is obtained, which was solved by numerical methods. The calculations were carried out in the Debye approximation, taking into account the screening effects. As a result, the dependence of the degree of ionization of lithium, hydrogen, and uranium atoms on concentration and temperature at different percentages of these atoms in the substance is presented: 10-85-5%, 9-90-1%, respectively.
