The heavy engineering arm of Larsen & Toubro has flagged-off the most complex and final assembly of Cryostat, the largest stainless-steel, high-vacuum pressure chamber in the world. The immense stainless-steel cylinder, which weighs 650 tonnes and measures 30 meter in height and diameter, will house the largest of the liquid helium-filled magnets that create the reactor’s torus. To enable the magnets to operate with maximal efficiency, they are cooled to minus193 degree Celsius, a little above the boiling point of nitrogen. The vacuum will help to maintain this temperature despite its nearness to hydrogen plasma heated to 150,000,000 degree Celsius, around 10 times greater than the temperature at the core of the sun.

The project scope for L&T Heavy Engineering is divided into three aspects. Firstly, the company was to manufacture assemblies at its state-of-the-art Hazira manufacturing complex. The second aspect involved constructing a temporary workshop at the project site in Cadarache, France for the assembly of various sectors. And finally, it is to integrate the Cryostat with the Tokamak Reactor building. With this flag-off, L&T Heavy Engineering has completed the manufacturing work planned in India.

L&T’s Heavy Engineering business won this prestigious contract from ITER India, a wing of Department of Atomic Energy, for the ambitious mega scientific project, conducted in collaboration of seven elite countries including India and with a project outlay of around USD 20 billion. The ITER team hope to achieve first plasma in December 2025.
