Abstract

Burning criteria for a D-³He fusion reactor have been investigated by using the 0-D power and particle balance equations and the IPB98(y,2) scaling law. A spherical tokamak (ST) configuration with the internal transport barrier (ITB) and the bootstrap current fraction of 100 % are assumed. As main results, the hot ion mode (T_i/T _e>1) and the high central beta are essential to realize a D-³He fusion reactor, and the confinement improvement does not reduce the requirement of the hot ion mode. The reactor size, the magnetic field, confinement improvement factor and the heat flux may be attainable if the hot ion mode is realized
