  • Patent number: 7267754
    Abstract: An improved process and device for the recovery of the minor actinides and the transuranic elements (TRU's) from a molten salt electrolyte. The process involves placing the device, an electrically non-conducting barrier between an anode salt and a cathode salt. The porous barrier allows uranium to diffuse between the anode and cathode, yet slows the diffusion of uranium ions so as to cause depletion of uranium ions in the catholyte. This allows for the eventual preferential deposition of transuranics present in spent nuclear fuel such as Np, Pu, Am, Cm. The device also comprises an uranium oxidation anode. The oxidation anode is solid uranium metal in the form of spent nuclear fuel. The spent fuel is placed in a ferric metal anode basket which serves as the electrical lead or contact between the molten electrolyte and the anodic uranium metal.

  • Patent number: 7250104
    Abstract: The methods and systems described provide for radiation assisted material deposition, removal, and planarization at a surface, edge, and/or bevel of a workpiece such as a semiconductor wafer. Exemplary processes performed on a workpiece surface having topographical features include radiation assisted electrochemical material deposition, which produces an adsorbate layer outside of the features to suppress deposition outside of the features and to encourage, through charge conservation, deposition into the features to achieve, for example, a planar surface profile. A further exemplary process is radiation assisted electrochemical removal of material, which produces an adsorbate layer in the features to suppress removal of material from the features and to encourage, through charge conservation, removal of material outside of the features so that, for example, a planar surface profile is achieved.
