The materials in a nuclear fusion reactor will face extreme conditions of particle bombardment and power load. Tungsten is widely considered the only appropriate material for plasma facing components due to its high melting temperature, good thermal conductivity and low sputter yield. The interaction of ionizing radiation with tungsten will lead to atomic displacements and thus to the...
The neutron damage of structural materials in fusion reactors is a crucial challenge. Present knowledge of the accumulated neutron doses and neutron fluxes indicates that new materials need to be developed and experimentally proved. For this purpose neutron source facilities for material tests are strongly required. They have to be capable of offering (i) continuous irradiation to get required...
The plasma-facing components in a nuclear fusion reactor have to withstand irradiation by 14 MeV neutrons, which are released in the fusion reaction of deuterium and tritium. A critical requirement of a future fusion reactor will be tritium self-sufficiency. A primary concern of tritium management is the potential for tritium trapping within or diffusion through the first wall of the reactor....
