ITER R&D: Auxiliary Systems: Introduction

ITER R&D: Auxiliary Systems: Introduction T. Mizoguchi * ITER Naka Joint Work Site, 801 -1 Mukouyama, Naka-machi Naka-gun, Ibaraki-ken 311 -0193 Japan
The auxiliary systems supporting the tokamak core also include fusion-specific technologies especially in the plasma heating and current drive system, the fueling and pumping system, the tritium system, the magnet power supply system and the plasma diagnostic system. These systems do not always relate to the critical path of the ITER construction, and some of them will possibly be improved or upgraded even after starting the plasma operation. The demonstration of the
full industrial production of these systems is not required, but it is, however, necessary to establish the technical feasibility of certain critical parts of these systems. Therefore, only critical components of these auxiliary systems have been developed during the ITER-EDA. In the following sub-sections, the progress and status of the R&D of these critical components are summarized, as well as the R&D relating to safety issues for ITER.
