The D-3He fuelled field reversed configuration reactor ARTEMIS-L

A neutron lean D-3He fuelled field reversed configuration fusion reactor is studied on the basis of the former high efficiency ARTEMIS design. Certain improvements such as effective axial contracting plasma heating and cusp type direct energy converters as well as an empirical scaling of the energy confinement are introduced. The resulting total neutron load onto the first wall of the plasma chamber is as low as 0.1 MW/m2, which enables the life-time of the first wall or the structural materials to be longer than the whole life of the reactor. The attractive characteristics of the neutron lean reactor follow these of the ARTEMIS design: it is socially acceptable as far as radioactivity and fuel resources are concerned, and electricity is cheaper than that from a light water reactor. Critical physics and engineering issues of the ARTEMIS-L reactor are clarified. (author). 6 refs, 3 figs
