Prospect of Spherical Tokamak towards a Power Reactor -Challenge towards the Lowest Aspect Ratio Tokamak- 6. Feasibility of Advanced Fuel Fusion Reactor

Abstract

Feasibility of D-³He fusion reactor has been investigated by using 0-dimensional power and particle balance equations and the IPB98(y,2) scaling. A self burning spherical tokamak (ST) D-³He reactor requires the high Ti mode and low impurity contamination. The beta value, the confinement improvement factor (H_H98y2) and the superconducting magnet should be improved from the present level.
