- Plasma Physics (Physics/ECE/NE 922) Seminar
- Core transport model validation towards building the physics basis for the SPARC tokamak
- Time: 12:00 pm
- Place: Zoom Meeting
- Speaker: Pablo Rodriguez-Fernandez, Massachusetts Institute of Technology
- Abstract: The validation of turbulent transport simulations and integrated modeling frameworks is essential for the design of fusion devices that operate in unexplored burning plasma regimes. This talk presents work devoted to understanding the validity of the local transport approximation, widely used in current predictive frameworks. Cold-pulse experiments have long been considered strong evidence of the existence of dominant non-local effects in the core of tokamak plasmas, suggesting that the core transport models used to predict burning plasmas in SPARC and ITER would need to be revisited from the ground up. This work demonstrates that the complete behavior of such experiments can be recovered by a fully local turbulent transport model, as long as multi-channel stiff transport is considered. This provides confidence in the predictions of SPARC performance, revealing an ample margin to net fusion gain in a medium-size tokamak.
