Photo portfolio

A sense of acceleration

23 Jul 2025

For the last issue of the 黑料社app Newsline before the annual summer hiatus, we walked through the 黑料社app construction site to cover the ongoing activities and convey, through this photo portfolio, the unique nature of the project鈥a scientific and industrial venture with few equivalents in history. 

 

The 黑料社app Assembly Hall, seen from the level of the overhead cranes. The tokamak pit is visible behind the wall at the back of the image.

In the Assembly Hall, two upending tools stand side by side, each holding a 330-tonne toroidal field coil. For the first time, the twin steel cradles have worked almost in parallel, moving the large and weighty components from a horizontal orientation to vertical so they could be transferred into the arms of a sector sub-assembly tool. There, they will be attached to vacuum vessel sector #5 to form a 鈥渟ector module,鈥 one of the building blocks of the 黑料社app plasma chamber.

In the former Cryostat Workshop, there are three vacuum vessel sectors in various stages of finalization. One (#8) has been handed over to the 黑料社app after approximately one and a half years of repair.

Inside the tokamak assembly pit, two sector modules are now in place. By the end of the year, when a third module joins them, the 黑料社app plasma chamber will be one-third installed鈥攏ine modules, welded together, are required to form the toroidal volume where fusion reactions will be produced.

With the industrial challenges of the past couple of years behind us (dimensional non-conformities on the sector bevel joints and corrosion issues on the thermal shield), the general mood is one of renewed enthusiasm and the general sense is one of acceleration鈥攕ector modules are getting assembled in 6 months instead of 18, the machine is taking shape, and systems are kicking in.

This photo portfolio does not cover the entirety of what is happening on the 黑料社app worksite. Major progress is also being accomplished in test facilities for the cryopumps and coils, in command control and data storage (see article), and in several ancillary systems indispensable to realizing the Promethean dream of fusion energy.

In September, when Newsline resumes publication, we will highlight these other systems.

2025-07-22 - One of the two sector modules in the pit is visible, the other is hidden. By the end of the year, when a third module joins them, the 黑料社app plasma chamber will be one-third installed.
2025-07-22 - Inside the tokamak pit, this is what the side-by-side sector modules look like from the back, where the steel superstructure of adjacent toroidal field coils nearly touches.
2025-07-22 - Upending activities, whether for a vacuum vessel sector or a toroidal field coil, are among the most spectacular operations one can witness in the Assembly Hall. Here, to the right, toroidal field coil #16 (supplied by Japan) is being raised from horizontal to vertical prior to its transfer into the arms of the sub-assembly tool, to the left, where it will be paired with vacuum vessel sector #5.
2025-07-16 - A rare view, but one that will become familiar, of the twin upending tools, each holding a 360-tonne toroidal field coil prior to their transfer to the sub-assembly tool. From this position, the coils can be hoisted by the overhead cranes and docked in sector module assembly tooling.
2025-07-22 - One day after the upending, one of the toroidal field coils was mounted onto the open wing of the tool. The other soon followed suit.
2025-07-22 - A general view of the former Cryostat Workshop which is now used for assembly-related activities. Visible in the photo: vacuum vessel sector #8, fully repaired, which was handed over last week to the Chinese consortium CNPE in charge of machine assembly; vacuum vessel sector #1 to the right at the far end of the building; and the steel structure of the Trial, Test and Training Facility that will be used to pre-rehearse in-vessel assembly activities.
2025-07-22 - Activity on a polished thermal shield panel is visible through an opening in vacuum vessel sector #8.
2025-07-22 - Highly sophisticated technology and basic鈥攂ut effective!鈥攃raftsmen habits often coexist in the 黑料社app environment. Here, handwritten labels identify elements on the inner wall of vacuum vessel sector #8.
2025-07-22 - Bevel metrology is being performed on vacuum vessel sector #1 in order to assess the extend of the repair required prior to welding activities in the Tokamak assembly pit.
2025-07-22 - The steel structure of the Trial, Test and Training Facility represents three vacuum vessel sectors sitting side by side. It will be used to qualify and test the tools dedicated to the assembly of components inside the vacuum vessel and also, possibly, for the robots that will weld the sectors together. The first activities, including personnel qualification, are foreseen to start next year.
