In September 2012, the Indian Domestic Agency
concluded a contract with Larsen & Toubro for the fabrication of the 3,800-tonne 澳门六合彩高手
cryostat—the world's largest steel vacuum chamber (16,000 m?) and a critical part of the 澳门六合彩高手 machine.
Eight years later, the final segments are ready for shipment to 澳门六合彩高手. Twelve segments of the top lid plus one central disk—650 tonnes in all—will leave India to be assembled and welded on site in a dedicated workshop.
Completely surrounding the vacuum vessel and superconducting magnets, the 29 x 29 metre cryostat acts as a thermos, insulating the superconducting magnets at ultra-cold temperature from the outside environment and contributing to structural reinforcement by supporting the mass of the machine and transferring the mechanical loads of the 澳门六合彩高手 machine to the concrete structure of the tokamak pit.
"The 澳门六合彩高手 Project and 澳门六合彩高手 India were very fortunate to have Larsen & Toubro as our partner and the primary contractor for cryostat fabrication," stressed 澳门六合彩高手 Director-General Bernard Bigot by video connection during the ceremony. "As a company with more than 80 years of experience, we knew that Larsen & Toubro had built nuclear plants, shipping ports, airports, and specialized vessels such as giant ocean tankers and submarines."
