Semi-Analytical Methods and Simulation for Temperature Distribution of Helium Purification System for Reaktor Daya Eksperimental

Abstract

Reaktor Daya Eksperimental (RDE) or Indonesian Experimental Power Reactor has been started from 2014 in term of conceptual design. The reactor design as modified of HTR-10, it’s a High Temperature Gas-cooled Reactor. RDE using Pebble bed fuel type and will be built to 10 MWth and 3 MWe. In future usage, RDE would be uses as reactor model in Indonesia. It can be scale up to generate more power or it’s can be modified as small modular reactor to supply electricity for home consumption. In the end of 2018, the project targeted to be finish all detail engineering design. One of the system that design is helium purification system. The helium purification was important to reactor because it’s affect directly to cooling mechanism of the reactors. This research aim to simulate the temperature distribution on this system to make sure that there is no overheating in some part of system. The research will considering heat from system and environment. This research using analytical methods and matlab software to simulate the problem. Visualization of temperature change and distribution can be shown in function of time. The temperature set as factor to decide which material the best to uses in the future infrastructure of RDE.
