Application of Monte Carlo Methods to Neutron Space-Time Kinetics

The paper proposes a method of direct simulation, which is based on Monte Carlo methods, for solving the neutron space-time kinetics problems. By directly simulating the behavior of neutrons and precursors of delayed neutrons, results are obtained. Eliminating various approximate approaches that are always necessary for other methods, this method is universal. To check its validation, relevant program has been developed with appropriate approximations, and has been used to calculate the test problems. The calculation results show it is practical to deal with the kinetics problem by the direct simulation approach.
