Rezumat:

One of the main directions from the Romanian R&D radioactive waste management program, initiated in 1992, four years before the start-up of the Cernavoda Nuclear Power Plant, is to establish the treatment and conditioning technologies for low and intermediate radioactive waste generated from operation of the plant.

Researches for the treatment of the liquid radioactive wastes from the Decontamination Center have showed the ion-exchange method as the best solution for their treatment.

The treatment or conditioning of the spent resins have to consider both the presence of the large number of radionuclides and the organic base of the ion exchangers. The adopted solution should not significantly increase the costs of waste management but has to limit at a maximum practicable extent the contamination and irradiation of the operating staff, population and the environment. The dose limits for workers and population are approved by the Regulatory Body

The selected conditioning process is the bituminization using industrial bitumen, I 60-70, made in Romania, having good characteristics.

The paper presents stages of the research project, technical conditions for the process and advantages of the bituminization of spent resins.
