    Abstract

    The electrical conductivities are reported for pure copper as well as
    for four different types of copper alloys, viz. CuNi, CuNiBe, CuCrZr and CuAl2O3, the latter three of which are under consideration for their applications in the structural components of ITER (International Thermonuclear Experimental Reactor). The alloys have undergone different pre-irradiation heat treatments which simulate the possible thermal histories of the material in ITER, and have been irradiated with fission-neutrons in the DR-3 reactor at Risø at temperatures in the range 100 - 350°C up to doses of 0.3 dpa. In some cases postirradiation annealing at 300°C for 50 hours has been carried out. The CuNi and CuNiBe have the lowest conductivities (£ 40% and £ 55% of that of pure Cu), and Cu-Al2O3 the highest (75-90% of pure Cu). The results are discussed with reference to equivalent Transmission Electron Microscopy results on the microstructure of the materials and to data from mechanical testing.
