Central solenoid stack completed
2026-06-23 - The sixth and last module of the ITER central solenoid is installed at the top of the stack in June. The achievement is the result of close coordination between ITER engineers, the US Domestic Agency, and the CNPE assembly consortium.
Commissioning of liquid nitrogen (LN₂) plant completed
2026-06-11 - After years of intensive installation and tests, the ITER LN₂ plant is now ready for service. The European teams have successfully cooled down the two nitrogen refrigerators, completing the commissioning of the system. The plant has shown that it can deliver the required cooling power (1,300 kW at 80 K) and can perform reliably in various scenarios.
Five modules now in pit
2026-05-27 - Five sector modules are now in the ITER tokamak pit. Vacuum vessel sector module #4 was installed in an overnight operation from 26 to 27 May 2026.
Magnet cold test facility begins operating
2026-05-21 - The first D-shaped toroidal field coil is successfully cooled down to 4 Kelvin (K), or minus 269 °C, over a 12-day period in May 2026 in the ITER magnet cold test facility and high-current testing is expected to begin shortly. The tests will provide essential information on magnet behaviour, cryogenic performance, electrical interfaces, instrumentation, and the critical joints that connect the layers of wound superconductor inside of the magnet coils.
Emergency Power Supply buildings: ready for equipment
2026-05-04 - The Emergency Power Supply Buildings—two on either side of the Tokamak Complex—house the systems that will step in instantly if the main electricity supply is disrupted on the ITER site. On 4 May, the European Domestic Agency team and contractors celebrate the "ready for equipment" milestone.
And then there were four
2026-01-29 - Four sector modules are now in the ITER tokamak pit. Vacuum vessel sector module #8 (left, with rigging still attached) was installed in an overnight operation from 28 to 29 January 2026.
