Experimental devices in Osiris reactor to study effects of radiations on fusion reactor materials

Within the framework of Technology Research Program on controlled fusion initiated by European Communities, the services des Piles de Saclay (S.P.S.) of Commissariat a l'Energie Atomique (C.E.A.) have been requested to realize some necessary irradiations to study the under flux behaviour of materials which are possible candidates for controlled fusion reactor. This paper describes the devices, generally adapted from a standard model ''the COLIBRI'', which allow to carry out, in the OSIRIS reactor, irradiations on the three great families of fusion reactor materials: lithium containing materials of breeding blanket for in situ tritium production, protection materials, structural materials
