Abstract
The Compact Materials Irradiation Facility (CMIF) project will provide a high-energy, high-flux neutron source for material irradiation research which will be indispensable for the long-term Accelerator-Driven Advanced Nuclear Energy (ADANE) project in China. CMIF is a Be(d, xn) neutron source driven by a 10 mA @ 50 MeV continuous wave (CW) deuteron beam with a granular flow target. This paper presents numerical studies of a granular beryllium target which adopts inclined granular flow to serve as both the target body and also the heat carrier. First of all, the flow constancy of the chute flow is investigated. Next the relationship between the irradiation conditions and the beam-target parameters is studied. To investigate the heat processing ability of this kind of target, the heat deposition and transfer in the target are simulated numerically. Finally, the heat removal for the backplate and also irradiation damage are investigated.
