First wall, limiter, and magnetic coils in compact concepts

Concern over the dominance in mass and cost of the fusion power core (FPC, i.e., first-wall/ blanket/ shield/ coils) for many large, low-powered density MFE approaches has led recently to serious consideration of the compact option. Power densities within the FPC approaching those of light-water fission reactions (i.e., 10-30 times greater than for superconducting MFE systems); projected costs relatively insensitive to large changes in unit costs ($/Kg) used to estimate FPC and associated reactor plant equipment (RPE) costs, as well as uncertainties in the associated physics and technology; considerably reduced size and mass of the FPC with potential for block (single or few-piece) installation and maintenance; and the potential for rapid, minimum-cost development are general characteristics being sought through the compact reactor options
