Flow network models of the upper plenum of reactor vessel and the primary inlet plenum of intermediate heat exchanger (IHX) of MONJU were advanced and each model was validated by the measured data obtained in the previous system start-up tests (SSTs). Then the whole plant dynamics in a plant trip transient of MONJU were simulated by incorporating these flow network models. The natural circulation in the primary and secondary heat transport systems were also validated by these test results. From these validations, we concluded that the plant dynamics model incorporated the advanced models in Super-COPD code could simulate the whole plant dynamics in good accuracy both in the transients and natural circulation conditions and that it was applicable to predict the next SSTs.
