Abstract (en)
[origin: WO9621933A1] A method for reducing radioactive waste, particularly oils and solvents in nuclear power stations and military research centres, and a device therefor, are disclosed. The method essentially comprises feeding the waste into a tank (1) in which it is continuously stirred, preheating the waste, performing a chemical precipitation treatment, feeding the mixture into a centrifuge (2), performing an electrostatic or conventional filtration step, and testing the level of radioactivity. The treatment is continuously repeated until the desired level of decontamination is reached.
