Compatibility of improved confinement regimes with reactor requirements
The reactor physics requirements are outlined in terms of characteristic performance measures. Four reactor designs of different scope are taken as examples. ITER is based on the edge localized mode (ELM)y H-mode as an operating regime demonstrated over many energy confinement times. Designs for power producing reactors require higher power densities and bootstrap current fractions, and therefore higher values of normalized beta. The capability of different enhanced confinement regimes, combining internal transport barriers with the L- or H-mode edge to satisfy these demands, together with the requirements on helium pumping and divertor power load, is discussed.
