摘要

EDF has been working on developing the use of innovative technologies to- undertake civil engineering inspections, with a particular focus on drones, in order to improve the maintenance of different structures within a nuclear site. Since 2016, several drone inspections have been conducted on nuclear plants to inspect part of a cooling tower, the reactor-containment buildings and the main turbine hall. This new tool, which offers a fast operational inspection capability, is equipped with a high-resolution camera to take multiple pictures of the target structure. The pictures enable the generation of high-quality orthophoto maps and thus a global view of the structure, which facilitates the analysis of defects classification. While currently defects are only detected with the manual assistance of experts, EDF R&D department is working on optimising the data processing of images and building new tools to automatize detection of concrete disorders.
