Abstract: A rotating tritium target used in high intensity neutron generator (HINEG) with 1o1 n/s neutron intensity was proposed in this paper. The technical challenges, mechanical and cooling design of the rotating tritium target were introduced and the key design limit value was given. The heat transfer process of the rotating tritium target system was simulated and analyzed by CFD method. The results showed that the maximum temperature was about 48C when the target system was under steady operation. That means the cooling design can realize the cooling of this rotating tritium target effectively, which makes no release of the tritium and melting of the target.
