Uranium bismuth solutions or dispersions of USn3 in liquid bismuth- lead-tin are proposed as fluid fuels for a power breeder or converter. These fuels offer advantages of high specific power, unlimited burn up, good neutron economy, and low over all operating costs which might lead to truly economical nuclear power. A simple and effective chemical process based on the extraction of liquid metal with fused salts will remove fission products in a concentrated form for use or storage. A process for the continuous separation of U233 from thorium in the blanket is described. Several design possibilities are discussed.
