Nuclearization projects of a tomographic atom probe and of an electropolishing machine for researches on neutron irradiated materials at the atomic scale

Abstract : The Tomographic Atomic Probe (TAP), located in LECI, in the CEA/Saclay LECI hotlab facilities, 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 unparalleled chemical and spatial sensitivity, hence it presents 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, LECI undertook the nuclearization project of the TAP. This project, which is a major stake for LECI, includes several milestones, namely the manufacturing of a glove box, the instrumental nuclearization, then the nuclearization of the rooms (engineer-ing studies and building works to accommodate irradiated samples) associated with the safety, security and radiation protection studies of this project. As TAP needs specific samples (with a needle shape) to be studied, this project is associated to the nuclearization project of a sample preparation machine
