Managing complexity for integrated fusion reactor design using a differentiable graph-based MDAO framework: PROCESS as a case study
Timo J. Bogaarts, Willem Rutten, Felix Warmer
Integrated design of nuclear fusion reactors requires combining an increasingly large number of models from different disciplines self-consistently, with model selection and parame…
Geodesic torsion of the magnetic field line and other predictors of coil non-planarity in QI stellarators
Andrea Pavone, Sehyun Kwak, Felix Warmer
Stellarator magnetic fields are often realized with non-planar modular coils with their out-of-plane bending being one of the main engineering challenges. We ask whether the non pl…
A novel discontinuous-Galerkin deterministic neutronics model for Fusion applications: development and benchmarking
Timo Jos Bogaarts, Felix Warmer
Neutron interactions in a fusion power plant play a pivotal role in determining critical design parameters such as coil-plasma distance and breeding blanket composition. Fast predi…
Global gyrokinetic analysis of Wendelstein 7-X discharge: unveiling the importance of trapped-electron-mode and electron-temperature-gradient turbulence
Felix Wilms, Alejandro Bañón Navarro, Thomas Windisch +8
We present the first nonlinear, gyrokinetic, radially global simulation of a discharge of the Wendelstein 7-X-like stellarator (W7-X), including kinetic electrons, an equilibrium r…
