Cautious ITER chiefs opt for 2026 target

摘要

The redesign and recosting of the ITERfusion project took a step closer tocompletion last month when the project'scouncil approved a step-by-step approach to construction designed to reduce the risk of something going wrong. Under the new plan, only a stripped-down reactor will be ready In 2018 to produce a plasma of normal hydrogen. Researchers will not attempt to achieve a burning plasma, which requires a fuel of deuterium and tritium, until late 2026 - up to two years later than planned - after further components have been added.
