Recently, the core component of the Cryostat system, the "Cryostat Base", successfully completed its assembly. This critical milestone marks significant progress in the construction of the BEST facility.
As the first core component installed in the main hall, the Cryostat Base is primarily welded from three parts: the skirt, the cylinder, and the bottom cover. The skirt has an outer diameter of approximately 18m, while the cylinder has an inner diameter of about 11m, a total height of around 4m, and a total weight of nearly 400 tons. During the R&D and manufacturing process, the project team overcame three major technical challenges: precision assembly of oversized components, achieving mm-level positioning; welding technology for ultra-thick plates, achieving a 100% weld pass rate and mm-level deformation control; and safety control in heavy lifting, accomplishing error-free hoisting of nearly 400 tons.
The successful assembly of the Cryostat Base not only signifies that the manufacturing of this component has entered a new phase of system integration but also fully demonstrates our company's strong capabilities and exceptional technical expertise in fusion energy engineering. Moving forward, the project team will continue to uphold a problem-solving spirit and spare no efforts to ensure timely completion of BEST objectives with high quality.
