Description
Summary:To ensure security on nuclear power plants, Electricite De France (EDF) uses radiographic inspection for systematic pipe control. The extreme temperature and pressure conditions to which pipes are submitted may generate structural defects that must be detected and characterized. The control procedure consists in introducing a gamma-ray source inside the inspected pipe and in imaging radiation onto radiographic films located on its periphery. Radiograph testing consists in interpreting the acquired radiographs and in building up a diagnosis on the basis of both the information they provide and the past experience.
