Integrated design and performance analysis of the KO HCCR TBM for ITER

다국어 초록 (Multilingual Abstract)

<P><B>Abstract</B></P> <P>To develop tritium breeding technology for a Fusion Reactor, Korea has participated in the Test Blanket Module (TBM) program in ITER. The He Cooled Ceramic Reflector (HCCR) TBM consists of functional components such as First Wall (FW), Breeding Zone (BZ), Side Wall (SW), and Back Manifold (BM) and it was designed based on the separate analyses for each component in 2012. Based on the each component analysis model, the integrated model is prepared and thermal-hydraulic analysis for the HCCR TBM is performed in the present study. The coolant flow distribution from BM and SW to FW and BZ, and resulted structure temperatures are obtained with the integrated model. It is found that the non-uniform flow rate occurs at FW and BZ and it causes excess of the design limit (550°C) at some region. Based on this integrated model, we will perform the design optimization for obtaining uniform flow distribution for satisfying the design requirements.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Integrated analysis is performed with the conventional CFD code (ANSYS-CFX). </LI> <LI> Overall pressure drop and coolant flow scheme are investigated. </LI> <LI> Manifold design is being performed considering flow distribution. </LI> </UL> </P>
