Application of a Two-Fluid Theoretical Plasma Energy Confinement Scaling to Current Tokamak Reactor Designs

A two-fluid theoretical model of heat transport in tokamaks is developed based on microinstabilities. A τ_E scaling of the form has been determined from this transport model. The theoretical τ_E scaling is used to determine the smallest size tokamak fusion reactor for two cases, ignition and Q = 5 steady state. Parameters are in good agreement with Tokamak Ignition/Burn Experimental Reactor II designs based on empirical Kaye-Goldston τ_E scaling.
