Experimental contamination and decontamination studies on JET remote handling tools and materials when exposed to tritium
Tests were performed to investigate the tritium release processes occurring when using remote handling tools on tritium contaminated INCONEL 600 material. Tritium surface contamination of these tools after operation on tritium contaminated material and following exposure to HTO was also investigated. One remote handling tool, in particular, was decontaminated using a high temperature technique. Additional tests were performed to evaluate the degree of contamination of materials including INCONEL 600, Aluminium alloy, PVC rigid and Stainless steel 316 and 304 exposed to tritium gas and/or tritiated water. Exposure time and temperature of exposure, post-exposure off-gassing time and tritium concentration were varied during the experiments. The effectiveness of various decontamination techniques on materials exposed for different periods of time was also assessed.
