The calculation of charged particles motion trajectories of SNF at magnetoplasma separation stage

Abstract

Currently the problem of spent nuclear fuel (SNF) reprocessing is relevant and studied in many countries. Existing methods of radiochemical reprocessing can not fully meet all the economic, energy and environmental needs of humanity [1]. Recently, the physical principles of magnetoplasma (MP) method of SNF separation is actively developed and investigated in NSC KIPT. This method consists in separation of nuclear fuel (NF) from fission products (FP) in the plasma phase [2]. During MP method application it is also expected the preliminary purification of SNF from some FP at the thermal heating stage [3]. At the next stage - the ionization stage - the complex multicomponent substance is converted into the plasma. Then directly NF is separated from FP at the magnetoplasma separation stage in plasma rotated in crossed electric and magnetic fields. The motion trajectories of NF and FP charged particles are greatly differ, therefore, NF and FP can be spatially separated [4]. Particles of NF and FP will get to the respective collectors, located in different places of SNF separation plant. Subsequently NF can be reused in different types of nuclear reactors.
