Definitions

  • the invention relates to a process for the production of spherical fuel or Hutzstoffp firmwaren from an oxide of the group of heavy metals uranium, thorium, plutonium or mixtures thereof comprising the steps of preparing a starting solution of the nitrates of at least one of the heavy metals, adding a first reagent from the group Urea and / or ammonium carbonate and / or ammonium bicarbonate and / or ammonium cyanate and / or biuret, adding at least one second reagent in the form of PVA and / or THFA to adjust the viscosity of the solution, dripping the solution into microspheres, at least superficial solidifying the Microspheres in an ammonia-containing atmosphere, collecting the microspheres in an ammonia-containing solution and then washing, drying and thermal treatment.
  • the object of the present invention is to develop a process which retains the known good properties of fuel or hull cores, which are produced by the solution / gel process, but dispenses with the use of problematic organic substances. Also, a concentrated solution of water-soluble complex cations of heavy metals is to be provided to allow easy further processing while avoiding the disadvantages inherent in the prior art. It should easily be made a stable solution that is to drip.
  • the second reagent is added to the solution at room temperature, the second reagent should be dissolved in solid form to avoid dilution of the solution.
