Abstract

In this work, the entry to burn, flat-top burning plasma operation and exit from burn have been investigated with improved modelling capabilities. Feasible high Q burning plasma operation scenarios have been developed for the ITER baseline operation within its operation constraints, such as the coil limits and heat loads. It has been observed that the W concentration needs to be maintained at a low value (n_w/n_e < ∼1.0×10^-5) to avoid the radiative collapse and early termination of the discharge. This work will be the basis for further optimization study, which will be necessary as the understanding of burning plasma physics improves. Disclaimer: ITER is the Nuclear Facility INB no. 174. This paper simulates plasma physics processes, neutron production and fusion performance during ITER operation; nevertheless the nuclear operator is not constrained by the results of this paper. The views and opinions expressed herein do not necessarily reflect those of the ITER Organization.
