Power exhaust scenarios for EU-DEMO

F. Subba, W. Van Uyten, S. Wiesen2025年8月Nuclear FusionIF 3出版社

We present an analysis of possible power exhaust scenarios for EU-DEMO. We employ the SOLPS-ITER code with the newly developed advanced fluid neutral model to scan a relatively wide range of neutral pressure divertor and impurity concentration in the core to test the existence of a suitable finite-extension operational space. Ideally, such a region should provide low target power fluxes, negligible erosion, high He divertor compression, and low impurity core concentration. Within the approximations of our model, we identified a non empty region where this long set of constraints can be satisfied. Here we use the constraints , and  eV, the latter being a proxy for detachment. This region corresponds to an upstream density within the range (large but not necessarily prohibitive), Ar separatrix concentration and divertor neutral pressure ranging from 40 to 50 Pa. This is encouraging, in view of a more detailed analysis to be performed on the best-performance area.

This paper analyzes possible power exhaust scenarios for the EU-DEMO fusion reactor. It uses advanced simulation tools to identify a suitable operational space that balances factors like low target power fluxes, negligible erosion, high helium exhaust, and low impurity concentration in the core plasma. The study found an encouraging region with specific ranges of upstream density, argon concentration, and divertor neutral pressure.
