Abstract:
Nuclear power plant technology has been growing rapidly. Nowadays, research and development had been taken place especially passive utilization of safety feature.
The purpose of this research is to assess a natural convective heat transfer characteristic at containment AP1000 model by using natural air circulation. The analysis method used in this research is finite volume byusing computational fluid dynamic (CFD) code. Based on numerical analysis result, the containment of AP1000 model becomes cooler with existence of baffle. This result indicated that the baffle as air director work properly and a better cooling system is achieved. The new concentric cylinder heat transfer correlationderives from containment model with baffle is proposed in the form of : Nu = f (Ra)*
