The inside of the thermo-nuclear fusion research reactor at JET is an environment hostile to human beings. In order to maintain and repair the reactor, as well as reconfigure it with new components before any new series of fusion experiments, a bespoke Remote Handling system was developed at JET.

The design and operation of the Remote Handling system requires a myriad of different technologies, all of which are also applicable to ITER, the next generation fusion research project.
