Abstract

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