Unique Swiss bellows engineering design approved for ITER fusion reactor project
Kompaflex AG has designed, built and successfully tested a large prototype bellows for the ITER tokamak fusion project in Cadarache, France. The bellows will be used to isolate the ultra-high vacuum inside the cryostat from the building environment, whilst withstanding the extreme operating conditions of the fusion reactor. After meeting the challenging requirements of the ITER specification, a further 85 bellows will be manufactured, some as large as four meters in size.
ITER will be the world's largest experimental fusion facility and is designed to demonstrate the scientific and technological feasibility of fusion power for energy purposes.
The huge ITER cryostat is around seven floors high and provides the high vacuum, ultra-cool environment for the ITER vacuum vessel and the superconducting magnets at the centre of the fusion reactor. The cryostat has over 200 access ports—some as large as four metres in size—that provide through-routes for cooling systems, magnet feeders, heating, diagnostics, and the exchange of components.
