X-ray techniques are commonly used in the fields of non-destructive testing (NDT) of industrial parts, material characterization, security and examination of various other specimens. The most used techniques for obtaining images are radioscopy for 2D and computed tomography (CT) for 3D imaging. Apart from these two imaging techniques, where X-ray radiation penetratesmatter, other methods like r...

Since the beginning of the nineties, the CEA (the French Atomic Energy Commisssion), with developing the CIVA NDT expertise platform is greatly involved in the development of simulation tools. Over the years, and with successive versions of CIVA, the results of modeling research work have been being integrated into the software both for ultrasonics and Eddy current techniques. In order to fullf...

It is a well-established fact that in industries relating to aerospace, automotive, boating, sports, weapons technology and the like, the usage of composite materials is ever increasing and will continue to do so in an exponential manner. Modern composite materials that are being researched and produced aim at satisfying engineers who are continuously searching for materials that exhibit high s...

Non-destructive testing (NDT) of aerospace structures has gained significant interest, given its non-destructive and economic inspection nature enabling future sustainable maintenance repair operations (MROs). NDT been applied to many different domains, there is a number such methods having their individual sensor technology characteristics, working principles, pros cons. Increasingly, approach...

New digital detectors were developed for medical applications, which have the potential to substitute the X-ray film and revolutionise the radiological technique. Digital Detector Arrays (DDA: Flat Panel Detectors, Line Detectors) and Imaging Plates (Computed Radiography) allow a fast detection of radiographic images in a shorter time and with higher dynamic than film applications. Companies re...

Problem of nuclear power plant (NPP) safe operation and risks reducing for nuclear power plants is one of the most actual ones. Taking into account the fact that NPP unit lifetimes are being extended beyond their design period, this problem becomes more and more important. One of the main and critical subsystems for NPP safe operation is steam generator (SG) consisting of (except other systems)...
