On design and development issues for the FRC and related alternate confinement concepts

Two prior D-3He field-reversed configuration (FRC) reactor designs, ARTEMIS and SAFFIRE are reviewed to identify key physics, technology, and design issues for FRC development. It is concluded that the D-3He FRC can potentially offer a cost competitive and environmentally compatible power plant if the technology issues can be suitably resolved. The D-3He FRC also appears to be particularly attractive for non-electrical application such as 3He breeding or hydrogen production. An important developmental issue becomes whether or not a D-T version should be employed as the first-generation unit. If so, emphasis must be placed on methods to handle high neutron and heat first-wall loadings, e.g. by use of a liquid first wall. Also, the development of improved thermal energy conversion cycles such as the use of liquid metal MHD becomes an important goal.
