Yes I have seen the advocacy for Liquid Fluoride Thorium reactors and there are some apparent tantalizing advantages over current Uraniumreactor designs like ability to burn plutonium as a starter fuel, less production of transuranics, higher fuel burn efficiencies, etc.
Professor Egil Lillestol of Bergen University has been pushing thorium for some years now, and thinks that Norway should set the trend in building a prototype accelerator-driven reactor in which a massive particle accelerator converts thorium-232 to uranium-233 by irradiating it with slow (spallation) neutrons generated by the impact of a 1.6 GeV proton beam on a lead target.
