Abstract

The ARIES study is a community effort to develop several visions of tokamaks as fusion power reactors. The aims are: To determine their potential economics, safety, and environmental features; to identify the physics and technology areas with the highest leverage for achieving the best tokamak reactor. The ARIES-III design is the subject of this paper. The ARIES-III research activity focuses on the potential of D-3He-fueled tokamaks because they may offer even greater environmental and safety advantages than DT-fueled reactors. Analyses have shown that the plasma power-balance window for D-3He tokamak reactors is small and requires a first wall (or coating) that is highly reflective to synchrotron radiation and small values of rajfc/r£ (the ratio of ash-particle to energy confinement times in the core plasma). Both first and second stability regimes of operation have been considered. The second stability regime is chosen for the ARIES-III design point because the reactor can operate at a higher value of t^Jtb - 2 (twice that of a first stability version), and because it has a reduced plasma current (30 MA), magnetic field at the coil (14 T), mass, and cost (also compared to a first-stability D-3He reactor). The major and minor radii are, respectively, 7.5 and 2.5 m. In this paper, a description of the ARIES-III research effort is presented and the general features of the ARIES-III reactor are described. The plasma engineering and fusion-power-core design are summarized, including the major results, the key technical issues, and the central conclusions.
