User Perceptions of Large Versus Small Fusion Devices and Electric Power Research Institute-Funded Compact Reactor Studies

The rationale for Electric Power Research Institute interest in small fusion systems is discussed from two points of view: economic demonstration of the competitive features of fusion energy and end use application. The physics base is summarized for five fusion schemes, which might enhance the prospects for a small fusion reactor, and scaling laws, which connect small systems with high-power-density systems are derived.
