Evaluation of Tritium Production in LiPb Blanket System Using Neutrons Analysis

摘要

Tritium production in LiPb blanket was evaluated by neutronics analysis with Monte Carlo code, MCNP using nuclear cross-section data from the FENDL-2.1 libraries. The result suggests the sufficient TBR (Tritium Breeding Ratio) can be obtained without using additional neutron multiplier such as beryllium. Based on the calculation, a plan for the integral experiment of a small LiPb system to verify it with our DD fusion neutron beam source was made. An integral experiment on LiPb with DD neutrons properly, transport and absorption of the neutron in a small test module was evaluated.
