Abstract

The JET Task Force Fusion Technology (TF-FT) has been launched with the aim of addressing issues related to JET and ITER. In this regard, studies related to the plasma–wall interactions identified erosion and deposition areas of the first wall of the vacuum vessel and provided the basis of our current knowledge on plasma–wall interaction processes at JET. In addition, characterisation of the properties of co-deposited layers covering the plasma exposed tiles have also been investigated and several detritiation techniques such as Laser Induced Breakdown Spectroscopy, or photon-cleaning have been successfully tested not only ex situ but also in situ. In the field of waste management, TF-FT also launched a series of tasks aiming at the detritiation of any kind of waste produced by a Fusion facility. Based on such studies it is now possible to scale up the developed detritiation facilities in order to be able to reach dimensions used at JET or ITER.
