ITER is the next generation fusion research device being built in the south of France that will achieve ‘a burning plasma’. This is one of the required steps on the way to commercial fusion power.
Remote handling is critical to ITER and RACE is at the heart of the action.
RACE is a partner in the ITER Neutral Beam RHS project led by Amec Foster Wheeler.
RACE is also a partner in the development of the Divertor RHS led by Assystem UK.

In preparation for the NB RHS contract RACE developed concepts for remotely replacing the beam sources of the neutral beam heating system. These high energy ion beams are used to heat the plasmas to 200million degC.
A monorail crane was designed with high lift in a compact space, with an innovative control system for high radiation environments. the crane will be built by Reel.
The beam line transporter operates along the full length of the beam line, like a industrial production line. It has a load capacity of many tonnes, haptic feedback and is fully remotely operated and remotely recoverable.
The Divertor is often called the exhaust system of a fusion reactor. It experiences massive heat loads as the 200million degC plasma is evacuated from the toroidal vacuum vessel. Over time the plasma facing surface of the Divertor will erode so every two years all 54 Divertor cassettes must be exchanged with only limited access. Each cassette must be positioned with millimeter precision. All the services will need to cut and then remade to exacting nuclear standards.
ITER Remote Maintenance – Designing for Remote Handling
ITER provides some seriously challenging environments for robotics: high radiation dose; elevated temperatures; limited access; large, compact equipment and some very challenging inspection and maintenance procedures to implement fast and reliably, without failure.
