3D Modelling and Static Structural Analysis of Bottom Reflector Experimental Power Reactor (RDE) using Solidworks Software

Abstract Bottom reflector design is important issue in BATAN's Experimental Power Reactor (RDE). The Bottom reflector is a pathway out of helium gas circulation to heat exchanger. It must sustain load of pebbles and structural itself. Solidworks software was used to perform 3D design and static simulation. 3D design was made in 6 layers and show that the model similar to HTR-10. Factor of safety was obtained in static simulation using 2 simplified parts. The result show that the minimum factor of safety are 153 in parts I and 151 in parts II. This static simulation result show that the model is suitable for RDE Farisy Yogatama Sulistyo1, Ari Nugroho2 and Syaiful Bakhri1
