Title: Process for the preparation of concentrates with high salt concentrations from the waste solutions of nuclear power stations
Inventor: DROZDA TAMAS
IPC: G21F9/06
Filed: 1983-06-07
Abstract: Radioactive waste solutions from nuclear power stations, which wastes contain organic materials, boric acid or borates and other inorganic salts, acids and alkalis, are prepared as concentrates using a process wherein the concentration of potassium ions in the waste is maintained at the lowest possible level. The organic material is oxidised with the stoichiometric amount of alkali metal permangate - sodium rather than potassium - in an acidic solution, and the products of this reaction are further oxidised so as to form a precipitate which is removed from the solution, and the solubility of the borate remaining in the solution is increased by adjusting the molar ratio of alkali to boron. The solution so formed is then subjected to a concentration step.
