  JOREK 3D non-linear MagnetoHydroDynamic (MHD) simulations of pure Deuterium
Shattered Pellet Injection in ITER are presented. It is shown that such a
scheme could allow diluting the plasma by more than a factor 10 without
immediately triggering large MHD activity, provided the background impurity
density is low enough. This appears as a promising strategy to reduce the risk
of hot tail Runaway Electron (RE) generation and to avoid RE beams altogether
in ITER, motivating further studies in this direction.
