A pyrolysis process was developed for treating radioactive spent organic solvent.On the basis of preliminary laboratory study, a pilot unit was constructed. The performance of the pilot unit was examined. The feature of the process was its high efficiencies of phosphorus fixation and radioactivity decontamination.A continuous run of 14 d was carried out successfully. A formula was recommended for the cementation of pyrolysis residue. The specified technical requirements were met for the cementation product and grout with the recommended formula.
