ITER is now one of the most ambitious energy projects in the world!
In the south of France, 35 nations are working together to build the world's largest tokamak, a magnetic fusion facility designed to prove the feasibility of fusion as a large-scale and carbon-free energy source, based on the same principle that powers our sun and stars.
The total of fifty high-security gates supplied by SOMMER (order volume approx. 15 million EUR) are located in a strong magnetic field, where they protect against radioactive radiation and heat. They are airtight and watertight and, despite being easy to operate, are designed to be particularly durable and low-maintenance.
46 SOMMER Heavy Nuclear Doors surround the tokamak on three levels and each of them closes an access cell (port cell)
Door weights of approximately 72 tonnes are achieved. Following the award of the contract in 2013 and initial complex planning processes, production was completed in 2019. Currently, the gates are being assembled on site and gradually put into operation. We make the customer's challenges our business.
Execution period
2013 until 2021
Client
Consortium VFR - Vinci/Ferrovial/Razel-Bec/Dodin-Campenon Bernard/GTM/Chantiers Modernes
Building owner
Fusion for Energy
Requirements
Shielding against gamma radiation, fire protection, air and water tightness, earthquake resistance
Products
Heavy Nuclear Doors (4 x 4 m) consisting of: 46 Port Cell Doors and 4 Lift Lobby Doors
Security
The fifty high-security gates are located in a strong magnetic field, where they protect against radioactive radiation and heat. They are airtight and watertight and, despite being easy to operate, are designed to be particularly durable and low-maintenance.
Solution
An integrated wicket door allows direct access to the rooms behind, without dependence on automatic drive and locking systems. Thanks to this special 'trick' of the door in the gate, the high requirements for evacuation in a given time could be met. Four other doors in different dimensions (up to 4.0 x 4.2 m) and weighing up to 20 tonnes are used as lift shaft closures.
