Real-time simulation of response to load variation for a ship reactor based on point-reactor double regions and lumped parameter model

► We calculate the variation of main parameters of the reactor core by the Simulink. ► The Simulink calculation software (SCS) can deal well with the stiff problem. ► The high calculation precision is reached with less time, and the results can be easily displayed. ► The quick calculation of ship reactor transient can be achieved by this method.
