Overview:

The lecture covers the overall system of fusion power plants,

composed of fusion reactor system, heat transfer & fuel cycle system, and power conversion system, based on the tokamak concept and its design. Issues and current status of fusion power plants development are addressed. The course deals with physics of burning plasmas and steady state operations in the fusion reactor system. For the heat

transfer & fuel cycle system, blanket technology including the material science are covered.
