The JT-60SA tokamak—a joint program of fusion research and development agreed and co-financed by the European Atomic Energy Community (Euratom) and the government of Japan—could restart cooldown operations and coil energization as early as March 2023, according to an  published by Fusion for Energy (Barcelona), the implementing agency for Euratom.

In 2021, a short circuit at the terminals of one of the machine's largest poloidal field coils had necessitated a pause in commissioning and a thorough assessment and analysis. One year of repair and further testing is now behind the joint Japan-Europe team, and plans are being laid for the restart of commissioning and possible first plasma next year.
