“…It also provides important three-dimensional data that would be very difficult and expensive to obtain using the traditional methods. The information generated by digital radiography can be easily integrated into computer analysis and modeling programs [3,4].…”

Dispersion type plate fuel elements were fabricated with U 3 Si 2 dispersoids in aluminium matrix and clad in Al-alloy for the modified core of APSARA reactor by standard picture framing technique followed by hot roll bonding operation. In general around 85% reduction in thickness was carried out in fabricating the finished fuel plates. These fuel plates were then characterized by digital X-ray radiography technique to outline fuel meat boundary and also for the quantitative analysis of surface uranium metal density in the fuel meat. In order to evaluate the surface uranium density a non destructive technique was developed in which X-ray radiography image was digitized and gray value was calibrated in terms of uranium metal density. In addition, fuel meat and clad thickness of fuel plate was determined along longitudinal section by optical microscopy.

“…FUJI, MAR) show a very high performance in neutron radiography and neutron diffraction experiments that feature either high flux neutron beams [2] or low g-background [3]. However, the application of such detectors is limited in the case of low flux neutron measurements by a high gbackground environment of a reactor hall because of a high g-absorption cross-section of the heavy elements in BaFBr and Gd 2 O 3 crystals.…”

The discovery of the neutron occurred in 1932, and the first neutron diffraction experiments were performed in the late 1940s. As usage progressively increased, the neutron has become a key probe in many fields of science, and sources around the world are now oversubscribed by experimenters. The European Spallation Source (ESS), and the Spallation Neutron Source (SNS), in the United State are new, high‐intensity sources under development that attest to the importance of neutrons as a probe. Because they are uncharged, neutrons are one of the most difficult particles to detect. Only a few elements in nature have a high affinity for neutron interaction. This article is organized as follows. The fundamental reactions upon which all neutron detection relies are described. Then a series of sections describe the main techniques of neutron detection and imaging: gas‐based, scintillator based, semiconductor‐based, film and image plates, and microchannel plates. In these sections, a few applications are noted. The section next to last focuses on neutron radiography/tomography, for which scintillator detectors and image plates are the primary imaging techniques. Some important reviews from recent literature for imaging techniques and for radiography are given. Techniques for (nonimaging) neutron detection have also recently been reviewed.
