ANALISIS DAN OPTIMASI DESAIN SISTEM REAKTOR GAS TEMPERATUR TINGGI RGTT200K DAN RGTT200KT

Abstract

Based on the mandatory of the Presidential Regulation No.5/2010, PTRKN-BATAN developing the conceptual design of cogeneration advanced power reactor based on High Temperature Gas-cooled Reactors (HTGR), those are named as RGTT200K and RGTT200KT. The design of the two variants RGTT system is not optimal yet and the thermal-flow specifications of both reactor cores are difference. Conceptual design of the RGTT200K and RGTT200KT systems should have the same thermal-flow core specifications, therefore no need to design two cores with different geometry of the core and fuel. To meet these requirements, the analysis and optimization of the conceptual design of RGTT200K and RGTT200KT system were performed in order to improve energy utilization factor (EUF) and unify the thermal-flow specifications of the reactor cores. Cyclepad software was used in the analysis of RGTT200K and RGTT200KT systems. The one dimension fixed control volume method is used in Cyclepad to solve the conservation equations that formulated for the control volume, therefore Cyclepad is very suitable for conceptual design of the thermodynamic cycle system. Optimization was carried out by solving of rising linear algebra equation of the RGTT200K and RGTT200KT models. This analysis and optimization resulting in the conceptual design of RGTT200K and RGTT200KT systems with same thermal-flow specification for the reactor cores, and an icrease in EUF to the level of 80.14% from 63% (for RGTT200K), and 78.02% from 63.6% (for RGTT200KT).
