Definitions

  • the present invention relates to the field of protection against radioactivity of materials, materials, contaminated objects or waste of any kind in general.
  • the invention provides a solution to the problem of preserving waste containing Cesium 137, Strontium 90 and other long-lived elements by providing a means of packaging for solid residues or solutions previously solidified by an appropriate means described in the application. Patent No. 79.07246 of the Applicant.
  • the process of the invention essentially consists in blocking the waste, introduced into containers of concrete or other material, using metallurgical slag with a glassy structure and finely ground.
  • slag with a particle size less than 2 mm, preferably ground to less than 0.1 mm and having a specific surface greater than 1500 cm 2 / g (measured according to the Blaine method).
  • the waste When the waste is coated in a slag slurry, the latter prevents the diffusion of radioactive elements.
  • the hypotheses put forward concerning the zeolitic effect of the silico-aluminum slags there exist in the network of free sites in which the alkaline and alkaline-earth ions are preferably housed, but also other ions (chromate , manganate zincate, etc.) which are also insolubilized, and the release of insoluble, precipitated and adsorbed adsorbed ions is extremely low.
  • slag and sqories are suitable for carrying out the process of the invention.
