Abstract  

The possibility of applying chemical treatment prior to evaporation was discussed in the present work. Using titanium hydroxide-cobalt ferrocyanide as coprecipitants allows fixation of high percentage of radioactive nuclides present (e.g. Cs 98%, Ru 90%, Sb 95%, Ce 98%, Am 95% and Pu 95%). Hence using such simple chemical separation before evaporation improves the process and leads to several advantages, e.g. raising the decontamination factor, reducing radioactive aerosol production and solving the problem of medium active waste treatment by adding the chemically precipitated solids to the high-active waste and the supernatant to the low-active waste, are examples for these advantages.
