Times Cited Count：0 Percentile：0(Physics, Applied)He minority ICRF Heating in ITER was simulated by the 1.5 D tokamak simulation code PRETOR and ICRF heating simulation code PION. It was found that the best heating efficiency in terms of the fusion power output is achieved with the smallest miority concentration ratio、0.5%, when the fuel dilution effect by the minority ions was taken into account. The overall heating efficiency is insensitive to the location of the resonance layer over a wide range of the minor radius position. Very efficient heating of the ITER plasma with He minority ICRF heating by spreading the RF depostion at three resonant locations was demonstarted by the PRETOR/PION simulation. In the Q=10 reference operation regime, ICRF is better than NBI by 8%, better than pure electron heating by 20%. In the low density region, ICRF is better than NBI by 15%, and better than electron heating by 50%.

Times Cited Count：3 Percentile：27.1(Nuclear Science & Technology)Recently, technical objectives of ITER were redefined aiming at the cost reduction of about 50% from the 1998 ITER design. Machine parameters which would satisfy the revised technical requirements under the engineering constraints were specified using a system code. The performance of these machines were studied and compared. As a result of these studies, final machine parameters were determined with revised conservative physics assumptions. This machine is referred as ITER-FEAT. It was shown that ITER-FEAT would achieve Q=10 in inductive operation with reasonable and conservative assumptions. Also, with an efficient current drive system and modest confinement improvement, possibility of Q=5 non-inductive operations in a steady state was shown.
