Tritium generation rate in the Li20Sn80 neutron irradiation experiments

In order to obtain the tritium diffusivity and solubility in the Li20Sn80 alloy, neutron irradiation experiments for the alloy have been performed. A diffusion model is used to account for the experimental results. The tritium generation rate was calculated by the Monte Carlo Nuclear Particle code (MCNP-4B) with the nuclear data library ENDF/BV to confirm the validity of an assumption in the model. The calculated results agreed with the experimental values within ±10% error. The tritium generation rate in the alloy is almost uniform. It means the assumption of the model is valid.
