The paper continues studies of the capabilities of plasma treatment of spent nuclear fuel and radioactive waste. The study is devoted to the problem of integration of the plasma source and separator, while the initial conditions of the substance input are considered by taking into account the possibilities of the process implementation. The results of calculations are presented in the one-particle approximation of 3D trajectories of the substance ions simulating the components of spent nuclear fuel. The calculations have been performed for the magnetic field generated by the coils and for the model configurations of the electric field approximated for the experimental capabilities. The electric potential configurations and the initial conditions pertinent to plasma injection along the magnetic field have been proposed, which allow efficiently separating singly charged ions of model substances characterized by masses of 150 and 240 amu, energies in the range of 0.02–20 eV, and an initial angular spread in velocities of 60°. The distance between the separated beams with different masses is found to be 10 cm for the characteristic separator size of 1 m.
