“Borée gas pipelines as long as a skyscraper”: Iter is preparing to purify the merger plasma with a titanic and daring project

The ITER project. Moreover, recognized as one of the largest world scientific companies, focuses on fusion energy, a promising and potentially inexhaustible source. Moreover, To achieve its objectives, the team has implemented an innovative system called Boronization. Additionally, Moreover, This technique is essential to maintain the purity of plasma, a key component of the fusion process. Nevertheless, Thanks to the application of a thin layer of “borée gas pipelines long skyscraper”: boron on the surfaces exposed to plasma. For example, this system strives to minimize impurities and ensure optimal operation of the reactor.

Boronization: a crucial innovation – "borée gas pipelines long skyscraper":

The boronisation is a sophisticated process that involves the use of diborane. In addition, a compound of hydrogen and boron. Nevertheless, This gas is injected into the Tokamak at a concentration of 5 % in a gas -carrying gas. Moreover, Once inside. Meanwhile, the diborane breaks down and deposits on the walls of the plasma thanks to a method assisted by luminescent discharge. Therefore, This process makes it possible to create a cold plasma which ensures a chemical bond of the boron on. Meanwhile, the surface of the material.

To carry out this operation on a large scale. more than a kilometer of pipes are installed inside the Tokamak building, with an additional 400 meters inside the vessel and 21 gas injection points. These “borée gas pipelines long skyscraper”: complex infrastructure reflect the magnitude and ambition of the ITER project. According to Gabor Kiss. an engineer in integration of refueling processes, these adaptations should not disturb the installation sequences of the factory.

International collaboration. design challenges – "borée gas pipelines long skyscraper":

The ITER project benefits from an unprecedented international collaboration to meet technical challenges. Although ITER design initially provided for a luminescent discharge cleaning for maintenance. the adaptation of this “borée gas pipelines long skyscraper”: technology for frequent boronization posed two major challenges. The first concerns the compatibility of the high energy anode design with frequent cycles. Tests to come to Tokamak East in China should provide answers on this subject.

The second challenge was the determination of the location of anodes to guarantee uniform boron coverage. To resolve this problem, international collaboration has been implemented. Tom Wauters. specialist in plasma-paroi interactions in ITER, underlines the importance of this cooperation with experts from the International Tokamak Physics Activity. Thanks to modeling. collaborative tests with the Tokamaks Asdex Upgrade (Germany) and West (France), the team decided to add four additional anodes to the vessel to obtain the most efficient boron distribution possible.

Operational frequency. safety measures

With the advancement of the design, operational questions arise, in particular the frequency to which the boronization must be carried out. Recent studies suggest that one application could be effective for 2.5 to 12.5 weeks, with a maximum planned interval of two weeks.

Since the diborane is toxic and explosive, specific security measures are imperative. The compound will be stored in a secure “gas cabin” built outside the diagnostic building. Any non -decomposed diborane pumped out of “borée gas pipelines long skyscraper”: the Tokamak must be neutralized. Two destruction methods are assessed: heat the gas to 700 ° C for thermal decomposition, or use a owner chemical trap. These measures guarantee the safety of staff and the environment.

Future prospects. installation

With a defined long -term strategy, the ITER project is advancing towards the installation of its boronization system. The space required for the Diborane elimination system is already in terms of development in the Tritium building. The project plans to start the installation in 2028, thus demonstrating its determination to overcome technical and logistical challenges.

By exploring these innovative solutions and based on international collaboration, ITER is positioned at the forefront of merger research. How will these advances influence the future of fusion energy and the global energy transition?
