| titleOfInvention | METHOD FOR RADIOACTIVE WASTE DISPOSAL |
| abstract | 1. A method for the disposal of radioactive waste, including contacting the initial sample of radioactive waste with a selective sorption agent for the estimated time until the maximum possible extraction of radioactive components, subsequent immobilization of the mixture in the place of production storage, characterized in that as a selective sorption agent for recovery from waste, containing predominantly long-lived isotopes of technetium and neptunium, they use powdered depleted uranium dioxide, the dispersion of particles of which it does not exceed 50 microns, in the form of an aqueous suspension with a ratio of solid phase to liquid phase, respectively 2.0-2.5 g / l, the sorption process is carried out in the temperature range from room temperature to 95 ° C and normal pressure under aerobic or anaerobic conditions . ! 2. The method according to claim 1, characterized in that before the contacting of the initial sample of radioactive waste with a selective sorption agent, the valence state of the sorbed isotope ions is determined spectrophotometrically, and after contacting the solution of radioactive waste with an aqueous suspension of depleted uranium dioxide, the solution is filtered and liquid spectrometry is carried out control the degree of sorption, which is calculated by the following mathematical formula:! ! where I is the registered count rate of the solution after filtration (imp / min); ! I0 is the count rate of the initial solution (imp / min). |
