  • Based on a three-equation model,the real-time thermal-hydraulic simulation code for plate type fuel reactors introduced proper constitutive equations which calculate the heat transfer coefficient,friction pressure drop and other parameters of plate type fuel reactors’ rectangle coolant channels.A transient flow distribution for multi-channel model and a solution of core flow among coolant channels was established,looking up table method is used to solve water-steam corporality parameters.The Reactivity Insertion Accident(RIA) and Loss of Flow Accident(LOFA) which had been defined in the IAEA 10MW MTR benchmark program is analyzed by the code programmed and executed with the real-time simulation support system SimExec.The result shows that the code is precise and proper for real-time thermal-hydraulic simulation of plate type fuel reactors.
