[en] This annual report summarizes activities performed by the EURATOM-Cea association in 2003 but only those concerning plasma-facing components are detailed. A full scale prototype mock-up of the ITER divertor vertical target has been high heat flux tested. The reference solution CFC mono-blocks made of SEP NB31 tiles and CrCrZr tubes confirmed a good behaviour under fatigue testing. Studies on high flux tested primary first wall panels have showed that cracks can be directly related to a problem of manufacturing or welding. The applicability of the hot isostatic pressing (HIP) technologies for manufacturing primary first wall is being investigated through the fabrication and testing of mock-ups. Samples of nano-structured SiC have been obtained by HIP of green-compacts made up of nano-powders synthesized by laser pyrolysis. Another task has been to assess the risk of failure in cascade of flat tiles under convective heat flux. The expected phenomenon of cascade failure did not occur during the tests. Tests concerning the erosion of graphite tiles have been performed. Chamfering angles for the new tiles of the MKII-HD divertor have been optimized to insure a good shadowing of the edges for the 12 reference plasma configurations. Pre-tests of 3-dimensional calculations of JET divertor tiles have been performed. The detritiation of plasma-facing components through the use of a laser beam has been investigated. Thick tungsten coating by chemical vapor deposition had been studied for copper divertor component. (A.C.)
