KAWASAKI, JAPAN―Toshiba Energy Systems & Solutions Corporation (hereafter “Toshiba ESS”) has announced today that it has completed its third manufacturing of toroidal field coils for ITER. This type of toroidal field coil has been entrusted by the National Institutes for Quantum and Radiological Science and Technology as one of the largest toroidal field coils in the world. This third manufacturing of the toroidal field coils was shipped to France following the first and second toroidal field coils, which were shipped in 2021.
ITER is the world’s largest fusion experiment and is being conducted in France with seven parties, including Japan and the EU, for the purpose of demonstrating the scientific and technical feasibility of fusion energy, which is expected to be one of the key energy sources in the future. In fusion power generation, deuterium and tritium are kept in a plasma state of more than 100 million degrees Celsius, and the heat generated by the fusion reaction is used to generate electricity.
The toroidal field coils are superconducting coils that generate a magnetic field to confine the high-temperature plasma required for the nuclear fusion reaction. Eighteen toroidal field coils will be used in ITER, with each toroidal field coil a D-shaped superconducting coil with a height of 16.5 m, width of 9 m, and weight of about 300 tons. Toshiba ESS is in charge of manufacturing four of these toroidal field coils, and all shipments will be completed with the fourth coil scheduled for shipment next spring.
Toshiba ESS will support the ITER project, which is called the “Sun on Earth,” by using the manufacturing technologies and knowledge of large-scale energy equipment that Toshiba ESS has cultivated over the years, and will contribute to the realization of future energy, and ultimately, carbon neutrality.
