Global thermal model of DEMO tokamak

The DEMO tokamak is composed of systems operating at very different temperatures, which in addition vary depending on the operational state. The relative thermal expansions/contractions as well as the heating/cooling power exchange between different tokamak systems (in-vessel components, magnets and thermal shields) need to be determined to ensure a consistent tokamak design. Numerical analyses of components and systems performed at JSI represent a key input at development of DEMO tokamak design.
