【Abstract】 The fast neutron burst reactor is a chain reactor that can operate upon prompt critical state. In this paper, the kinetics characteristics of fast neutron burst reactor are described., the kinetics eqation and analytical solution upon prompt critical state are developed. The results of experiment are described, measurements of the pulse characteristic parameter that fast neutron burst reactor operated upon prompt critical state are presented, and the basic kinetics parameters are obtained. The theory accords well with the experiments.更多还原
