Examination of the Entry to Burn and Burn Control for the ITER 15 MA Baseline and Other Scenarios

Authors: C.E. Kessel, S.-H. Kim, F. Koechl, V. Leonov

Abstract: The entry to burn and flattop burn control in ITER will be a critical need from the first DT

experiments. Simulations are used to address time-dependent behavior under a range of possible conditions that

include injected power level, impurity content (W, Ar, Be), density evolution, H-mode regimes, controlled

parameter (Wth, Pnet, Pfusion), and actuator (Paux, fueling, fAr), with a range of transport models. A number of

physics issues at the L-H transition require better understanding to project to ITER, however, simulations

indicate viable control with sufficient auxiliary power (up to 73 MW), while lower powers become marginal (as

low as 43 MW).
