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.

The €20bn Iter (International Thermonuclear Experimental Reactor) project will replicate the reactions that power the sun and is intended to demonstrate fusion power can be generated on a commercial scale.
The steel and concrete superstructures nestled in the hills of southern France will house a 23,000-tonne machine, known as a tokamak, capable of creating what is essentially an earthbound star.
Millions of components will be used to assemble the giant reactor, which will weigh 23,000 tonnes and the project is the most complex engineering endeavour in history. Almost 3,000 tonnes of superconducting magnets, some heavier than a jumbo jet, will be connected by 200km of superconducting cables, all kept at -269C by the world’s largest cryogenic plant.

The Dynamic SNC consortium announced, 25 March, that it had completed a successful dry run of using an upending tool required to build the world’s largest tokamak nuclear fusion reactor for the ITER project under construction in France.
