Overview of progress on the EU DEMO magnet system design

The DEMO reactor is expected to be the first application of fusion for electricity generation in the near future. To this aim conceptual design activities are progressing in Europe (EU) under the lead of the EUROfusion Consortium in order to drive on the development of the major tokamak systems. In 2014 the activities carried out by the magnet system project team were focused on the Toroidal Field (TF) magnet system design and demonstrated major achievements in terms of concept proposals and of consolidated evaluations against design criteria. Several magnet system R&D; activities were conducted in parallel, together with broad investigations on High Temperature Superconductor (HTS) technologies. In this paper we present the outcomes of the work conducted in two areas in the 2014 magnet work program: (1) the EU inductive reactor (called DEMO1) 2014 configuration (power plant operating under inductive regime) was the basis of conceptual design activities, including further optimizations; and (2) the HTS R&D; activities building upon the consolidated knowledge acquired over the past years.
