Conditioning of Radioactive Waste Resulted From the Treatment of Liquid Waste From the Romanian Nuclear Power Plant

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. The selected process was the bituminization using industrial bitumen, I 60–70, made in Romania, which had very good immobilizing characteristics. The paper presents stages of the research project, technical conditions for the process and advantages of the bituminization of spent resins.
