Francina Canadell, Project Manager at F4E, stated: “The cryopumps required a flawless production chain to secure the tight tolerances all through machining, welding and assembly. Thanks to a smooth coordination, we managed to meet the standards and even solve some unforeseen issues on the spot.” Her remarks highlight the precision and teamwork involved in meeting the project’s high standards.
At ITER, these cryopumps will maintain the low-density environment needed for the fusion reaction to occur within the reactor. Of the eight units supplied by F4E, two are designated for the cryostat, while the remaining six will link to the vacuum vessel via the divertor. The cryopumps function by capturing gas particles on cryopanels, which are chilled to approximately 4K (-269°C). This ultra-low temperature enables the trapping process, after which the pumps release the particles to recycle unburned fuel.
The delivery marks a significant milestone for ITER, a global effort to develop fusion energy. In the years ahead, the ITER Organisation plans to test these cryopumps under actual cryogenic conditions by connecting them to the facility’s advanced cryoplant circuits. This testing phase will verify their performance in sustaining the vacuum essential for fusion experiments.
The collaboration between F4E, RI, Alsymex, and other partners reflects a well-coordinated effort to advance clean energy technology. By ensuring the cryopumps meet strict specifications, the team has laid a foundation for ITER’s next stages, bringing the project closer to its goal of demonstrating fusion as a viable energy source. The successful completion of this delivery underscores the importance of precision manufacturing and international cooperation in large-scale scientific endeavors.
