CONDITIONING TECHNOLOGY FOR RADIOACTIVE WASTERESULTED FROM THE TREATMENT OF LIQUID WASTEFROM THE ROMANIAN NUCLEAR POWER PLANT

摘要

For the conditioning of spent resins contaminated with radionuclides, such as: 137Cs, 134Cs, 60Co, 58Co, 57Co,54Mn, etc., techniques of direct immobilization in cement, bitumen and organic polymers have been tested. Theselected process was the bituminization using industrial bitumen, I 60-70, made in Romania, which had verygood characteristics.The paper presents stages of the research project, technical conditions for the process andadvantages of the bituminization of spent resins.
