Predictions of ITER Steady State Scenario Using Scaled Experimental Edge Profiles in DIII-D*

The DIII-D ITER demonstration shots replicated leading features of the ITER steady state scenario, including noninductive fraction ($f_{NI}$) above 100\%, $q_{95}\sim 5$, plasma shape, aspect ratio and $I_p/aB$. Integrated modeling with a theory-based (GLF23) model is used to extrapolate these results to the ITER steady state scenarios. The boundary conditions for GLF23 are set at $\rho = 0.8$ while the edge profiles at $0.8 < \rho < 1.0$ are scaled with the experimental local $\beta_N(\rho)$. The predicted values of $f_{NI}$ and fusion gain ($Q$) using the ITER Day-1 heating and current drive capability are close, but still somewhat short (by $\sim$10\%) in achieving the $f_{NI} =\,$100\% and $Q = 5$ goal. Sensitivities of $f_{NI}$, $Q$, edge and core stability, and gyrokinetic stability to plasma current, density, and density peaking, etc.\ will be discussed. Possible heating and current drive upgrades will also be explored.
