文摘

We have studied the core design of neutron transmutation doping (NTD) silicon reactors using material testing reactor (MTR) fuel elements. Silicon ingots are irradiated in the reflector area, outside the core. A large core has a small leakage of neutrons and thus burns fuel efficiently. However, since a large core has less neutron leakage, the irradiation efficiency of neutrons in the reflector area is also lower. We discuss the most efficient design of a reactor core based on our calculations of fuel consumption and level of silicon doping.
