Query: Plasma steering to avoid disruptions in ITER and tokamak power plants   Steering tokamak plasmas is commonly viewed as a way to avoid disruptions and
runaway electrons. Plasma steering sounds as safe as driving to work but will
be shown to more closely resemble driving at high speed through a dense fog on
an icy road. The long time required to terminate an ITER discharge compared to
time over which dangers can be foreseen is analogous to driving in a dense fog.
The difficulty of regaining plasma control if it is lost resembles driving on
an icy road. Disruptions and runaways are associated with three issues -- a
solution to one tends to complicate the solution to the other two: loss of
plasma position control, excessive heat deposition, and wall melting due to
runaway electrons. All three risks must be addressed for ITER to achieve its
mission and essentially eliminated before tokamak power plants can be deployed.
