| The study of the retention and desorption of hydrogen isotopes and helium atoms in first wall materials is key for the design of future fusion reactors, not only for their effect on the degradation of the wall properties but also for the implications in T management strategies. A diffusion model of the implanted H,D, T and He species in a 1mm thick first wall of Tungsten for the two initial phases of the proposed European laser fusion Project HiPER (namely, phase 4a and phase 4b) has been implemented using Tritium Migration Analysis Program, TMAP7. The effect of the prompt and working temperatures and the operational pulsing modes on the diffusion are studied. Although a detailed treatment of the different trapping mechanisms has been omitted, meaningful quantitative results on the accumulation, desorption and time intervals to reach a stationary state are presented and discussed. | |
