Problems will require in-depth examination and ‘time and budget’ to repair October 2022 file photo of the 30-metre-deep pit in the tokamak building being prepared for the Iter machine itself. Courtesy Iter. Defects have been identified in two key First-of-a-kind tokamak components for the International Thermonuclear Experimental Reactor (Iter) nuclear fusion plant under construction at Cadarache in southern France, with the €20bn project facing potential delays while repairs are carried out.

Iter said in a project update that the two components are the vacuum vessel thermal shields and the vacuum vessel sectors.

The issues “demand in-depth examination, creativity in devising corrective actions, and time and budget to repair”, Iter said.

The vacuum vessel thermal shields are actively cooled silver-plated elements, 20 mm thick that contribute to thermally insulating the plant’s superconducting magnet system operating at 4K, or minus 269C.
