The development of a novel particle transport and thermal-hydraulic calculation chain for the European DEMO

• A new multiphysics calculation chain has been developed by Aalto University and VTT. 2D fusion product distribution was obtained with the ASCOT source integrator. Serpent hybrid models featured homogeneous CAD-based STL geometries. Power deposition profiles were meant for Apros T/H WCLL breeding unit model. versatile under development at VTT University, featuring Monte Carlo orbit-following suite of codes, particle transport code Apros® thermal-hydraulic system code. This project aims to establish a comprehensive analytical environment that can aid researchers multiple stages during maturation DEMO. Plasma term have generated using code, providing input subsequent neutron calculations Serpent. These studies utilized geometry equatorial Water-Cooled Lithium-Lead (WCLL) blanket. Efforts towards optimization made, investigating leakages scalability these external simulations. Preliminary results reported along methodology converting tallied data into Apros-relevant input.
