Description
Summary:The possibility of using a direct-flow plasma centrifuge for separating the spent nuclear fuel is considered. The equations which describe the characteristics of the azimuthal motion and radial expansion of a fully ionized plasma jet under the action of a rotating transverse magnetic field of dipole configuration in the longitudinal static magnetic field are obtained. The analysis is performed both in the multicomponent approximation and on the basis of the one-component magnetohydrodynamic equations with account for the Hall effect. The computations are carried out for different values of the magnetic field confining the plasma. Based on the obtained dependences of circumferential and radial velocities of ions on the values of high-frequency magnetic fields , the separation characteristics of the plasma centrifuge are estimated in separating a two-component mixture modeling the spent nuclear fuel.
