Definitions

  • the present invention relates to a method for immobilizing ion exchange resins originating from the secondary circuits of pressurized water nuclear reactors and graphite-gas reactors.
  • the present invention relates to a process for the immobilization, with a view to their storage, of said resins.
  • the immobilization process chosen is that of concreting, that is to say the general process - known in itself - consisting of coating the products to be immobilized in a hydraulic binder.
  • the problem consists in carrying out a pretreatment of the resins making it possible to implement this immobilization process and, if possible, to obtain a product having the best properties.
  • the pretreatment process according to the invention is characterized in that the ion exchange resins are saturated with a base, preferably sodium hydroxide, under conditions such that the pH of the medium is greater than approximately 9 and that the release of ammonia is favored.
  • a base preferably sodium hydroxide
  • base a compound such as sodium, potassium, calcium or barium hydroxides.
  • sodium hydroxide is preferred. This product can be used in solid form or in solution.
  • the base used in the present invention is intended to ensure, by ion exchange, saturation of all the sites of the resins comprising an NH4+ ion, it is obviously necessary to carry out this exchange in an aqueous medium which can be consisting wholly or in part of the water which is generally present in the charge of the resins to be treated.
  • the pH of the (aqueous) medium should be above about 9; in fact, the pH must be high enough for the NH4+ ions released from the resins by exchange with the basic cation (Na+) not to remain in the dissolved state in said medium but to give rise to gaseous ammonia which will emerge from said medium
  • the amount of "base” used must be at least that which allows total displacement of the NH4+ ions by the cation of said base. In practice, since the proportion of cationic resins contained in the resins to be treated is often ignored, an amount of "base” is used which is at least sufficient for the cation of said base to saturate all the sites of the resins, assuming that all the resins treated are cationic it will be noted that the use of a quantity of base greater than that necessary to ensure the saturation of the sites can, to a certain extent, promote and accelerate the phenomenon of saturation.
  • the process as described above only causes ionic exchanges on the cationic resins contained in the resins to be treated. It turns out that, given the very low radioactivity of the resins treated and the specifications current to be respected, it has been determined that the anionic resins did not have too great harmful effects on the phenomena of setting of the hydraulic binder.
  • the process according to the invention can be improved by also stabilizing, by ion exchange, the anionic resins present in the resins to be treated.
  • This stabilization can be done by carrying out the ion exchange of OH ⁇ contained in the anionic resins with ions such as NO4 ⁇ , SO4 ⁇ , CH3COO ⁇ ...
  • ions such as NO4 ⁇ , SO4 ⁇ , CH3COO ⁇ ...
  • NO3 ⁇ ion the most interesting, because of the stability obtained, because of the ease of its use and because of its inertia with respect to the anions present during concreting, is the NO3 ⁇ ion.
  • the quantity of this anion (NO3 ⁇ preferably) to be used can advantageously be calculated by assuming that all the treated resin is of anionic type and that one aims at the saturation of all the sites of this resin.
