Prediction of performance in ITER-FEAT

Matsumoto, Hiroshi; Barabaschi, P.*; Murakami, Yoshiki*

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.
