Abstract

Pellet injection to D-T burning plasmas was analyzed using an integrated equilibrium-transport simulation code, TOTAL, for both tokamak and helical reactors. The condition of pellet injection required for the formation of an internal transport barrier and the dependence of plasma parameters in the steady self-burning state on the D/T ratio in the pellet were investigated. A simulation with different D/T ratios in the pellet revealed that the operational region of temperature and density varies with the D/T ratio. When a deuterium-rich pellet was employed, the amount of tritium to be used in the reactor was approximately 30%-40% less than that when the D/T ratio was 1.
