Iter nuclear fusion project reaches key halfway milestone

After a series of set backs the international project is back on track, say scientists, giving tentative hope for a major new source of clean power by 2025

An international project to generate energy from nuclear fusion has reached a key milestone, with half of the infrastructure required now built.

Bernard Bigot, the director-general of the International Thermonuclear Experimental Reactor (Iter), the main facility of which is based in southern France, said the completion of half of the project meant the effort was back on track, after a series of difficulties. This would mean that power could be produced from the experimental site from 2025.
