SUMMARY:Core transport model validation towards building the physics b
 asis for the SPARC tokamak\, Plasma Physics (Physics/ECE/NE 922) Semin
 ar\, Pablo Rodriguez-Fernandez\, Massachusetts Institute of Technology
DESCRIPTION:The validation of turbulent transport simulations and inte
 grated modeling frameworks is essential for the design of fusion devic
 es that operate in unexplored burning plasma regimes. This talk presen
 ts work devoted to understanding the validity of the local transport a
 pproximation\, widely used in current predictive frameworks. Cold-puls
 e experiments have long been considered strong evidence of the existen
 ce of dominant non-local effects in the core of tokamak plasmas\, sugg
 esting 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 b
 e recovered by a fully local turbulent transport model\, as long as mu
 lti-channel stiff transport is considered. This provides confidence in
  the predictions of SPARC performance\, revealing an ample margin to n
 et fusion gain in a medium-size tokamak.<br>
