MANAGEMENT OF OPERATIONAL ACTIVE WASTES ON JET
Activity levels of first wall components on JET and in the vacuum vessel are low during D-D operations and all maintenance and associated waste handling tasks can be carried out using "hands-on" techniques. Activation resulting from the production of 14 MeV neutrons during tritium pulses in the D-T phase necessitates the use of remote handling equipment for maintenance and waste handling. In addition to activation products and tritium, waste management will be affected by the presence of beryllium used as a first wall material. Studies have been carried out to estimate the volumes and characteristics of the wastes generated in both phases. The disposal options for the differing waste streams have also been investigated. The conceptual design of facilities for active handling and waste management tasks, required for the support of torus maintenance and intervention work, has been completed. These facilities, which include areas for decontamination of tools and equipment, equipment maintenance and storage, will be operational before the start of the D-T phase. A quality assurance plan has been developed for the identification and safe disposal of the active wastes.
