Operation with tritium plasma led to contamination of the JET in-vessel components with tritium at a level exceeding 12kBq/g, which is the Low Level Waste (LLW) threshold in the UK. Carbon tiles used at JET for protecting the pumped divertor and inner wall against heat and neutron flux create one of the Intermediate Level Waste (ILW) streams to deal with during the JET decommissioning in the future. To reduce quantity and cost of ILW disposal from JET, the study has been initiated for development of detritiation techniques. This paper presents a brief description of the study of the JET carbon tiles detritiation using flame heating.
