ITER is a collaborative international project to build the world's largest tokamak, a magnetic fusion device that has been designed to prove the feasibility of fusion as a large-scale and carbon-free source of energy based on the same principle that powers our Sun and stars.
Veolia Nuclear Solutions (VNS) was contracted to develop the preliminary design of the IVVS by Fusion for Energy (F4E), the body of the European Union that is responsible for the EU's contribution to ITER.
