Application of a 1-D predictive model for energy and particle transport to the determination of ITER plasma-SOL interface parameters

The constraints of divertor operation have been applied to ITER core plasma simulations by imposing boundary conditions which describe the effect of the divertor. At the nominal average core density for ITER with the ICPS transport model stationary operation with a fusion power multiplier Q of 12 –16 is obtained and a reasonable operating range exists. The relaxation to these stationary conditions is very slow, and transient values of fusion multiplier are appreciably higher.
