Static Structural Analysis of Ceramic Internals Experimental Power Reactor (RDE)

Abstract

In 2018, BATAN propose detail engineering design of Experimental Power Reactor (RDE). An important issue of RDE is Ceramic Internals or Reactor Pressure Vessel (RPV). Ceramic Internals is pathway of helium gas, control rod, absorber ball and also pebble fuel. Its structural component must sustain by the load of 27000 pebbles fuel. A preliminary static structural analysis of bottom reflector, a part of Ceramic Internals, has been studied before, the result was satisfying and could be scale-up to analyse the Ceramic Internals with same methods. Design and static structural simulation are performed by using Solidworks software to study the factor of safety distribution in Ceramic Internals. The design was made in 16 layers with small dowel as the component to endure the movement. Factor of safety was obtained in static simulation using single simplified parts. The preliminary result show that the minimum factor of safety can handle the load of Ceramic Internals structural. This result show that the model is suitable for RDE design.
