  We present two-dimensional global simulations of mitigated and vertically
unstable disruptions in ITER in the presence of runaway electrons. An elongated
plasma in free-boundary equilibrium is subjected to an artificial thermal
quench and current-profile flattening, followed by one or more massive material
injections and RE avalanche. Scenarios of major disruptions as well as upward
and downward vertical displacement events are considered. Results provide
important insights into the effects of runaway electron formation, post thermal
quench current-profile, injection quantities and timings, and impurity flushout
on the overall evolution of disruption and the plasma vertical motion thereof.
Interplay between the various effects offers scope for potentially beneficial
runaway electron mitigation scenarios.
