Approach to Integrated Plasma and Engineering Modeling for Fusion Reactors

A seminar by Cami Collins

Abstract: The Fusion REactor Design and Assessment (FREDA) SciDAC project is developing a flexible, integrated modeling framework for design, assessment, and optimization of fusion reactors. FREDA leverages a model hierarchy combining theory-based plasma physics and multiphysics engineering models from both fusion and fission communities. FREDA uses IPS-FASTRAN as a backbone for plasma modeling, enhanced by newly developed Core-Edge Pedestal-SOL (CESOL) workflows extending from plasma core to plasma-facing components. The engineering suite, FERMI, provides self-consistent analyses including structural mechanics, thermal hydraulics, fluid dynamics, electromagnetics, and nuclear performance, enabling detailed evaluation of reactor components including the first wall, blanket, and magnets. Parametric CAD generation facilitates rapid, iterative geometry adjustments in response to evolving plasma and structural load requirements. Uncertainty quantification methods are being incorporated to assess sensitivity and robustness of design points. An overview and status of project goals will be presented.
