Reviews & Commentary

Fusion power is one of a very few sustainable options to replace fossil fuels as the world's primary energy source. Although the conditions for fusion have been reached, much remains to be done to turn scientific success into commercial electrical power.

Fusion research is driven by the applied goal of energy production from fusion reactions. There is, however, a wealth of fundamental physics to be discovered and studied along the way. This Commentary discusses selected developments in diagnostics and present-day research topics in high-temperature plasma physics.

Commentary | | Nature Physics

One way of realizing controlled nuclear fusion reactions for the production of energy involves confining a hot plasma in a magnetic field. Here, the physics of magnetic-confinement fusion is reviewed, focusing on the tokamak and stellarator concepts.

Energy-producing nuclear fusion reactions taking place in tokamaks cause radiation damage and radioactivity. Remote-handling technology for repairing and replacing in-vessel components has evolved enormously over the past two decades — and is now being deployed elsewhere too.

Commentary | | Nature Physics

Construction of the ITER tokamak, arguably the largest scientific project ever, is well under way in the south of France. Nature Physics spoke with ITER's Director-General, Bernard Bigot, about the challenges ahead — a conversation about physics, engineering, politics and culture.
