Frazer-Nash has been selected to support the Cryostat and VVPSS (Vacuum Vessel Pressure Suppression System) team at the ITER project near Cadarche in southern France.
The eight-month contract will see Frazer-Nash on-site at ITER carrying out an update of structural analysis to qualify the cryostat design against the ASME Boiler and Pressure Vessel Code.
The cryostat is a welded structure manufactured from stainless steel plates that are up to 180mm in thickness. It forms the vacuum-tight container surrounding the ITER vacuum vessel and superconducting magnets. When complete it will have a weight of 3,500 tonnes, an outer diameter of more than 28m and will be almost 30m tall.
The structural analysis work being carried out by Frazer-Nash is to confirm the structural integrity of the updated Cryostat design due to project change requirements.
