Abstract :
The ARIES-RS reversed-shear tokamak power plant was designed with β=5% and a high bootstrap current fraction of 88%. Three RF current drive systems are required to maintain the plasma equilibrium. They are ICRF fast waves, high-frequency fast waves and lower hybrid waves for seed current drive in various regions of the plasma. Based on a set of top-level requirements, the three RF systems have been envisaged and their launchers fitted into a special blanket sector. Structural materials chosen for the RF in-vessel components do not appear to pose a waste disposal issue for the blanket lifetime. The RF system for mid-plasma current drive is a topic for future research
