Abstract. Nonlinear MHD simulation results of pellet injection show that MHD
forces can accelerate large pellets, injected on the high field side of a
tokamak, to the plasma center. Magnetic reconnection can produce a reverse
shear q profile. Ballooning instability caused by pellets is also
reduced by high field side injection. Studies are also reported of the current
quench phase of disruptions, which can cause 3D halo currents and
runaway electrons.
