Numerical simulation of MONJU plant dynamics by Super-COPD using previous startup tests data

Yamada, Fumiaki; Ohira, Hiroaki

The advanced flow network models of the RV upper plenum and the IHX inlet plenum of MONJU were explained and validated by the previous SSTs. The whole plant dynamics of MONJU were also predicted using the validated flow networks. The natural circulation experiments both in the PHTS and the SHTS were conducted applying the previous SST conditions. The whole plant dynamics model with the advanced IHX model was also validated by these test results. Through these validations, we concluded that the present plant dynamics model of Super-COPD could simulate the whole plant dynamics in good accuracy, which was applicable to the next SSTs.
