FIELD: power industry.
SUBSTANCE: method and device are implemented when quasineutral axial symmetric multiple-component flow of plasma is obtained by means of plasma accelerator, during transportation of flow through azimuth device with transverse radial magnetic field, flow of plasma flow divided into masses through separating volume with stationary radial electric and homogeneous longitudinal constant magnetic fields, collection of ions of two groups of spent nuclear fuel (SNF) to ion receivers located on cylindrical surfaces. Ions of the third group of SNF are collected to annular end receiver.
EFFECT: group of inventions allows enlarging functional capabilities of plasma optic mass-separator owing to minimising negative impact of power and angular spreads of ions of various chemical elements in plasma flow and proper selection of the shape, quantity and location of receivers of groups of ions.
