An Experimental Power Reactor called RDE (Reaktor Daya Eksperimental) is small size non-commercial power reactor with the thermal power of 10 MW is being designed based on high-temperature gas cooled reactor (HTGR). The purposes of the RDE designed is to generate electricity for supplying electricity in Serpong research area and to supply thermal energy for experimental purposes. The design of energy conversion system in the RDE design is designed in cogeneration configuration with a Rankine cycle. To meet the design goals, the configuration of the energy conversion system for RDE is designed in a cogeneration configuration with a Rankine cycle. The reactor coolant temperature at the outlet is designed at 700 oC, and the steam temperature at the outlet of the steam generator is designed at 530 oC. The analysis of RDE cogeneration energy conversion system performance is concentrated on two parameters namely the thermal efficiency parameter and the parameter that states the energy utilization factor (EUF). The aims of this research aims is to calculate and analyze the optimal of the two parameters in the design of RDE energy conversion system. The calculation of these parameters and analysis of the performance of RDE energy conversion system are performed by simulation using computer code ChemCad. The simulation results show that the energy utilization factor of the cogeneration configuration for the RDE energy conversion system can increase the energy utilization factor by more than 60%. From these results it can be concluded that the energy conversion system in the cogeneration configuration can increase the energy utilization factor and can save the reactor fuel.
