Tokamak experimental power reactor: basic considerations and initiation of studies at Oak Ridge

Scoping studies initiated at ORNL in August, 1974 are addressing basic questions: the objectives of the EPR, essential features, ranges of dimensions, research and development required to provide design input, and alternatives that must be pursued until information for firm decisions becomes available.Twelve task areas are: project definition, plasma engineering and physics, blanket and energy conversion, shielding, tritium systems, tokamak device engineering, tokamak support systems, materials and fabrication, design integration, assembly and maintenance, facility planning and project engineering, and program management.Initial results include delineation of major questions, identification of appropriate objectives and criteria, development of models and limited parametric studies of plasma characteristics, and preliminary conceptual design of an energyrecovery blanket with provisions for breeding experiments in interchangeable modules.
