Fusion energy

This paper presents an overview of the main challenges that fusion research is facing on the road to a demonstration power plant. The focus is on magnetic confinement fusion. Most of the challenges are being addressed in the context of the ITER construction and exploitation. These include the demonstration of high fusion gain regimes of operation, the management of high heat and particle loads and the integration of the main technologies of a fusion power plant. In preparation of DEMO, reliable solutions for the breeding blanket and neutron resistant materials have to be developed
