Physics and technology issues in our present view of design of a Tokamak reactor

Abstract

The present conceptual designs of Tokamak reactors are generally driven by economical reasons towards steady state operation, smaller plasma current and reduced size. This evaluation finds its justification in the assumption of more or less optimistic improvements in physics and technology with respect to the present situation. Hopefully most of the problems associated with power and particle exhaust, ash removal, plasma disruptions, burn control will be solved in ITER. Therefore these problems will only be touched upon in this lecture? The physics needs about confinement, beta, profile control, will also be shortly analysed and compared with the already achieved results. The physics issues will be the argument of most of the lecture in this workshop. More attention will be devoted to what extrapolation is needed and can be foreseen in the technology of magnets, first wall, blanket. The requirements on structural and protection materials with respect to mechanical properties, heat transmission capability, fatigue, neutron damage and activation lifetime will be analysed and the necessary developments and R&D outlined.
