Conference paper


The International Fusion Reactor – ITER – is being designed and constructed with a high level of safety as an essential requirement. In order to meet the safety and performance objectives of the French regulatory authorities and of the ITER Organization requirements, the Tokomak Complex has been isolated from the potentially highly damaging effects of the hazard seismic loading by employing seismic isolation bearings. The Tokamak Complex seismic base isolation system and the Tokamak Complex structure have been designed by EGIS Industries as a member of the Architect-Engineer team ENGAGE. The design, manufacturing, qualification and installation of the seismic isolation bearings have been carried out by NUVIA Travaux Spéciaux.
