[Background]Fast neutron pulsed reactors are sensitive to wall scattering neutrons,and their waveforms are changed by reflected neutrons.In addition,their operation may be adversely affected when there are too many reflected neutrons.[Purpose]This study aims to solve the problem of fast neutron pulse reactor wall reflection neutron.[Method]The point reactor kinetic method containing the reflection effect,Monte Carlo method,and ANSYS were combined to analyze the Godiva-I transient process in fast neutron pulsed reactor with wall-reflected neutron effect.Firstly,the quench coefficient of the fas...
