Title: Nuclear Fuel Element
IPC: G21C3/33
Filed: 1966-10-15
Abstract: In a nuclear fuel element assembly comprising a plurality of longitudinally extending fuel elements, the fuel elements are secured to a support plate at one end of the assembly by means of spring pins which extend partially into holes in the ends of the fuel elements and partially into holes in the support plate, which latter holes are in alignment with those in the assembled fuel elements. The spring pins may be slotted, tubular pins of C-shaped cross-section, or be spirally shaped. A second support plate is secured to the other end of the fuel elements, extensions on these ends protruding into holes in the support plate which are larger in diameter than the extensions and these are thus free to move upon thermal expansion of the fuel elements. Rods extend between and are bolted to the support plates to hold them in position with respect to each other.
Patent ES-338574-A1 (ES)
Title: Process for making nuclear fuel materials
IPC: G21C3/62
Filed: 1967-03-28
Abstract: Nuclear fuel particles containing fertile and fissile material in oxide form are made by treating gel particles containing fertile material with a liquid containing the fissile material and calcining the resulting gel particles, which may have a fissile content of up to 15 atom per cent. For example thoria sol is dried by evaporation or is converted to spheroids by passing droplets through a dehydrating solvent, the gel particles formed being graded according to size the particles are contacted with aqueous uranyl nitrate solution (containing U235) by stirring together, by passing the solution over a column of the gel particles, or, preferably, by allowing the particles to fall freely through the treating solution and then into a body of wash and dehydrating liquid, for example a mixture of acetone with carbon tetrachloride or trichlorethylene. The gel particles are calcined at above 1100 C. in an argon-hydrogen atmosphere, placed in a tubular container and compacted to high density by vibration or swaying to form a fuel element. Uranyl fluoride, acetate, chloride, or sulphate may be used in the treating liquid instead of uranyl nitrate. Fuels comprising U238 as the fertile material and U233, U235, or Pu as the fissile material may be made by similar processes.
