Application of Simulink in Fast Calculation for Marine Reactor Parameters

The Simulink emulation model was established based on the six-group delayed neutron point reactor model and the core lumped parameter model with two sections to emulate the dynamic process of marine reactor, and the results were compared with those of related literature. The results show that precise emulation can be accomplished using Simulink with rather long average steps, and pre-time calculation of physical and thermal parameters can be achieved in ordinary micro-computer which is of significant meaning to the marine reactor operation.
