Esteyco Mechanics is heavily involved in the design, analysis and justification of many of the most critical systems in ITER since 2009. This covers a variety of systems including vacuum, safety, cryogenics, remote handling and a long etcetera. This long experience and broad understanding of the ITER project provide the group with a unique capability to address the challenging technical topics normally associated with such a complex project. This is recognized by both ITER Organization and Fusion for Energy with the continuous flow of relevant contracts assigned to Esteyco Mechanics over the years.
