[en] The International Symposium on Management of Low and Intermediate Level Radioactive Wastes, organized jointly by the International Atomic Energy Agency with the Commission of the European Communities, was held in Stockholm, Sweden, from 16 to 20 May 1988. All basic stages of management of low and intermediate level radioactive wastes (treatment, conditioning, waste form characterization and quality control, and disposal options) were addressed at the symposium. For the first time in IAEA practice the subject of treatment and conditioning of mixed radioactive and chemically and biologically hazardous wastes was also included in the programme. The papers presented at the symposium showed that substantial progress is still possible in the further development and improvement of the numerous existing technologies for waste treatment and conditioning. Much effort is being made to minimize the volume of waste, to reduce the total cost of waste management, and to improve the quality of immobilized wastes and the reliability of disposal. A great number of techniques available worldwide for the treatment and conditioning of radioactive wastes and several new treatment processes being developed in different countries were reported. The range and the novelty of this work indicate that substantial effort is continually being devoted to the improvement of treatment and conditioning techniques. It was strongly confirmed by many contributions at the symposium that waste product composition and quality should be adjusted to meet the disposal criteria and therefore depend on the disposal option selected. A range of disposal options were discussed at the symposium. Depending on many factors, including the geology and geography of the country concerned, waste composition, availability of appropriate abandoned mines and socio-political factors either deep underground disposal or shallow land burial or a combination of the two is being adopted for the disposal of radioactive wastes. The extensive description of the new Swedish repository for radioactive waste, the SFR, constructed in rock caverns below the sea-bed, was a highlight of the symposium. Refs, figs and tabs
