Abstract

As a part of IAEA collaborative research project, thermal stratification in MONJU hot pool has been predicted for the event of turbine trip. Predicted temperature distribution has been compared against the data measured in MONJU reactor. It is observed that stratification prevails in the pool for a shorter duration than that observed in the plant. Also, predicted axial temperature gradient at the stratification interface is larger than that measured in the reactor. Predictive capabilities of various turbulence models and the effect of thermal capacity of hot pool structures on stratification have been assessed by parametric studies.
