Operating point selection and burn stability control for the International Thermonuclear Experimental Reactor

摘要

The selection and burn-stability control of near-ignited operating points for the International Thermonuclear Experimental Reactor (ITER) are considered. High-electron-density ( approximately 1-2*10/sup 20/ m/sup -3/), low-electron-temperature ( approximately 6-10 keV) operating points are preferred, based on considerations of proximity to magnetohydrodynamic (MHD) stability limits, divertor operation, and fueling even though those points are intrinsically thermally unstable. Results from simple 0-D transport simulations suggest that these operating points can be effectively stabilized at Q<50 if neutral beam feedback based on total neutron flux measurements is used.
