Abstract: A two-group three-dimension space-time neutron kinetics model is applied to the RELAP5 code,which replaces the point reactor kinetics model.A visual operation interface is designed to convenience interactive operation between operator and computer.The calculation results and practical applications indicate that the functions and precision of improved RELAP5 are enhanced and can be easily used.The improved RELAP5 has a good application perspective in nuclear power plant simulation.
