Description
Summary:A temperature control mechanism is presented for the nuclear material design of a breeding blanket module. It aims at exploring the acceptable material fractions maintaining the thermal balance inside a blanket module, which support the temperature requirement for tritium release and inventory. One-dimensional neutronics model is utilized to discuss the calculations. It is found that there is a mutual influence in the blanket interior by using the multi-layers structure. Firstly, the pure Li 4 SiO 4 zones in the front area are the relative independent zones and have little thermal influence to other zones. The Beryllium zones only affect the adjacent zones, but the effect can be ignored. The second beryllium zone and the first mixed pebble zones are mainly limited to the reduced activation ferritic/martensitic material due to the lower temperature limitation. It indicates that the structural casing for nuclear materials should be reckoned in detail because of no cooling with it. It is confirmed that there is a temperature control methodology for the design of blanket nuclear materials using the linear variation of the temperature profile.
