The "Beating Heart" of the ITER Tokamak
The central solenoid module is one of six more or less identical elements which, once assembled, will form the "beating heart" of the ITER Tokamak. The Central Solenoid has been dubbed "the most powerful magnet in the world''.
This magnet found its way into the Assembly Hall of ITER Worksite. Once finalized, it will be placed at the very center of the Tokamak PIT.
Second Vacuum Vessel Lift
On Monday 20th : the second vacuum vessel sector crossed the Assembly Hall and is now held in one of the two sub-sector assembly tools. The 440 tones heavy weight will be outfitted there with thermal shielding and two toroidal field coils. Another Tokamak Sector prepared and placed in its assembly tool where the silver coated thermal shield boards and 2 other magnets will be installed in the next months, before transfer to its final location where the vacuum vessel sectors chamber will be welded together.
Start of TCC2 Site Activities
On Thursday 17th : The worksite 2 was on the stage with the first support installed by TCC2. Indeed, a weld was performed and underlined the beginning of the TCC2 site activities. The TCC2 assembly contract was signed in December 2020 by the ITER Organization and the META SNC. This contract is one of the last major assembly and installation contracts planned for first-phase ITER assembly. The TTC2 contract is for the installation of primary machine cooling water, test blanket module equipment, some vacuum pipework and vacuum vessel pressure suppression.
Europe delivers poloidal field coil #5
On Monday 26th, was delivered the Poloidal Field Coil #5, manufactured by Europe. One of the six ring-shaped coils required for the machine. It measures 17 metres in diameter and weights approximately 340 tonnes.
First Poloidal Field Coil Lift
On Wednesday 22nd was installed the Poloidal Field Coil #6. 9 temporary supports maintain the bottom cylinder. This 400-tonnes component—poloidal field coil #6 of 10 meters diameter is the first superconducting magnet to enter the Tokamak pit. Temporary supports will stay until the vacuum vessel is assembled and welded.
First Vacuum Vessel Lift
After several days of works preparation, tools set up, metrology with monitoring and tuning of the VV6 center of gravity, the lifting of the 440-tonnes Vacuum Vessel sector #6 and its positioning in the sector sub-assembly tool was done. Before the end of 2021, the 1,200-tonnes pre-assembly will be lowered into the pit, marking the first step in creating the Tokamak's toroidal chamber.
First thermal shield installed
On January 24th, the ITER assembly and construction teams successfully inserted the cylindrical Lower Cryostat Thermal Shield into the Tokamak pit. Its silver-coated panels are designed to minimize the radiation heat load that will reach the magnets operating at 4.5 K.
