A separation apparatus for separating a supply of high-level nuclear waste (HLW), where the HL nuclear waste is separated into high-mass and low-mass portions. The high-and-low mass portions of the HLW have respective atomic masses that are above and below an atomic mass cut-off point of the separation apparatus. The separation apparatus includes first and second ICP torches that are respectively mounted to and within an apparatus housing. The apparatus housing defines a cylindrical separation chamber and includes first and second magnetic elements which generate a magnetic field along the length of the separation chamber, and a plurality concentric ring electrodes which generate an electric field that is perpendicular to, and which crosses the magnetic field. The supply of HLW is subject to a mass separation process within the separation chamber using the set of crossed electric and magnetic fields.
