Core-edge integrated modeling of ARC: on the effect of impurity transport and detachment conditions
Marco Muraca, Pablo Rodriguez-Fernandez, Nathaniel T. Howard +5
Integrated modeling of ARC H-modes has been conducted to assess the feasibility of high-performance scenarios compatible with divertor detachment. The analysis incorporates self-co…
Impurity peaking of SPARC H-modes: a sensitivity study on physics and engineering assumptions
Marco Muraca, Pablo Rodriguez-Fernandez, Joe Hall +5
In this paper, an overview of the impurity transport for three H-mode plasmas in the upcoming SPARC tokamak has been provided. The simulations have been performed within the ASTRA+…
Integrated Modeling of SPARC H-mode Scenarios: Exploration of the Impact of Modeling Assumptions on Predicted Performance
Marco Muraca, Pablo Rodriguez-Fernandez, Nathaniel T. Howard +3
In this paper an extensive database of SPARC H-modes confinement predictions has been provided, to assess its variability with respect to few input assumptions. The simulations hav…
Combing physics-based and data-driven predictions for quantitatively accurate models that extrapolate well; with application to DIII-D, AUG, and ITER tokamak fusion reactors
Joseph Abbate, Emiliano Fable, Giovanni Tardini +3
Methodologies for combining the accuracy of data-driven models with extrapolability of physics-based models are described and tested, for the task of building transport models of t…
