Definitions

  • the present invention relates to a method for the transport and / or storage of chemical, radioactive or other waste.
  • the present invention provides an extremely simple and inexpensive solution to the problem, while providing security unknown until now.
  • waste in question provides for these purposes and according to the invention that an emulsion with a small volume of water, highly thixotropic, is prepared and that the additives are added to this emulsion.
  • waste in the form of a liquid, semi-liquid or muddy effluent.
  • the emulsion used also contains flame retardant additives and a catalyst which is stable in cold but active in hot.
  • this solution makes it possible to transport waste to an independent factory, freeing, for example, nuclear power plants from the problem of waste treatment.
  • the percentage of water in the emulsion is then reduced to a value allowing the addition of water or effluents. liquids accompanying the different forms of waste.
  • the emulsion will be of the maximum self-extinguishing type, by the use of all brominated, chlorinated, phosphated or other products from the manufacture of the base resin.
  • the emulsion can for example be mixed with cement to form blocks and to be coated for example according to the coating process described in Swiss patent no ........ (patent application no 2329/83, filed April 29, 1983).
  • This process consists in producing a mixture comprising waste (for example radioactive waste) in saturation in their storage water, a resin and a monomer, to form an emulsion with the waste, their water, the resin and the monomer and by adding to this emulsion a hydraulic binder to make a concrete.
