Transport simulations of ITER with empirical heat diffusivity scaling

摘要

Radiative mantle scenarios of the ignited ITER Engineering Design Activity(EDA) with argon and neon influxing are explored by computer experiments using special versions of the 1.5 dimensional(1.5-D)BALDUR predictive transport code. An empirical scaling law for the effective heat diffusivity, compatible with the ITERH-2 ELMy H mode scaling and validated against exper- iments, is applied. The prescribed flat density profiles, conductive heat loss across the separatrix of 200 MW and ratioτ_He/τE,r, of 10 are reached in the simulations.
