Abstract

The Tomographic Atomic Probe (TAP), located in the DMN/LECI, a hot laboratory in the department of irradi-ated materials of CEA, University Paris-Saclay, has become an essential technique for the fine characterization of nuclear materials. Indeed, this high-resolution three-dimensional microscope is a unique instrument because it allows an understanding of the phenomena at very fine scales namely the atomic scale with un-paralleled chemical and spatial sensitivity hence a major interest for the characterization of defects created by irradiation that are mostly visible at these scales. In the aim of studying neutron-irradiated materials with this instrument, the LECI undertook the nuclearization project of the TAP. This project, which is a major stake for the LECI, includes several milestones, namely the manufacturing of a glove box, the instrumental nucleariza-tion, than the nuclearization of the rooms (engineering studies and building works to accommodate irradiated samples) associated with the safety, security and radiation protection studies of this project. As the TAP needs specific samples (with a needle shape) to be studied, this project is associated to the nuclearization project of sample preparation machine.
