Computation research of high temperature reactor’s prompt neutron generation time

High temperature nuclear reactor in the field of MHD power generation and nuclear rockets have good application prospects. High temperature reactor has a pile of high core temperature, complex structures, whose physical performance parameters are rather difficult to compute. This paper studies the high temperature nuclear reactor prompt neutron generation time calculation method, introduces the calculation principle of a variety of methods and a new high temperature nuclear reactors calculation results. The results show that for the same reactor model, calculation results of several methods are in good agreement and the calculated results are credible.
