The European contribution to the ITER Remote Maintenance

• The article introduces the needs for remote maintenance in ITER.
• It also discusses some of the issues related to the cultural transition from tokamaks as plasma physics to nuclear reactors.
• It highlights the related cultural change and the implications on plant topology and maintenance.
• Then, it presents those remote handling systems that will be procured by Europe.
• The article emphasises the need of a major involvement of industries from now on.

For a first-of-a-kind nuclear fusion reactor like ITER, remote maintainability of neutron-activated components is one of the key aspects of plant design and operations, and a fundamental ingredient for the demonstration of long-term viability of fusion as energy source.The European Domestic Agency (EU DA, i.e. Fusion for Energy, F4E) is providing important support to the ITER Organisation (IO) in specifying the functional requirements of the Remote Handling (RH) Procurement Packages (i.e. the subsystems allocated to EU DA belonging to the overall ITER Remote Maintenance Systems IRMS), and in performing design and R&D activities – with the support of national laboratories and industries – in order to define a sound concept for these packages.Furthermore, domestic industries are being involved in the subsequent detailed design, validation, manufacturing and installation activities, in order to actually fulfil our procurement-in-kind obligations.After an introduction to ITER Remote Maintenance, this paper will present status and next stages for the RH systems allocated to EU DA, and will also illustrate complementary aspects related to cross cutting technologies like radiation tolerant components and RH control systems.Finally, the way all these efforts are coordinated will be presented together with the overall implementation scenario and key milestones.
