“…Failed rods and assemblies are problematic for NPPs and any information that can be gleaned from a failed rod may be valuable to the nuclear industry. Post Irradiation Examination (PIE) using radiography has been carried out on nuclear fuel extensively, for both intact and failed rods [Richards et al (1982); Davies et al (1986) NDT of spent fuel greatly reduces the cost of examination in comparison to destructive testing, as there is much less need for manipulation of the rod in expensive hot cells, and in a lot of cases the rod can remain in tact, thus containing fission products and radioactive isotopes.…”

a b s t r a c tImaging of nuclear fuel using radiation has been carried out for decades for a variety of reasons. Two important reasons are Physical Invertory Verification (PIV) and Quality Assurance (QA). The work covered in this review focuses on the imaging of nuclear fuel using ionising radiation. The fuels investigated are both fresh and spent, composed of assorted materials, and in various physical forms. The radiations used to characterise the nuclear fuel include g, a, b, muons, neutrons and X-rays. The research covered in this review, spans the past four decades and show how the technology has developed over that time. The advancement of computing technology has greatly helped with the progression of the images that are produced. The field began with 2D images in black and white showing the density profiles of g rays from within an object, culminating in 2013 when a pebble bed fuel element was reproduced in 3D showing each 0.5 mm UO 2 globule within it. With the ever increasing computing technology available to the industry, this can only mean an increase in the rate of development of imaging technologies like those covered in this review.

Small amounts of radionuclides of suitable half‐life can be used to observe the kinetics of mass transport and isotopic exchange in the equilibrium distribution of a (micro‐)component between coexistent phases. Quantitative assay of radioactivity is sensitive, precise and accurate and usually performed instrumentally. Though handling of radionuclides is restricted to authorized laboratories only, the combination of its potential and simplicity makes the radiotracer method an indispensable part of modern analytical chemistry.

Some applications of electrical tomographic techniques for the measurement of gas/liquid flows in packed columns are described. Electrical tomography is nonintrusive, of high temporal resolution, low cost, engenders no radiation hazard and is easy to implement. This mainly encourages the development of capacitance, resistance and inductance sensing techniques which are applied within volumetric fields of density, pressure, concentration, temperature, velocity or void fraction. The mentioned fields are instationary most of the time or they are of transient character. Therefore, not only temporal but also spatial resolution is required. X‐ray tomography is used for the visualisation of gas‐liquid flow inside packed columns. The measurement system consists of a fixed X‐ray tube and an array of 15 detectors. The spacial resolution is of the order of 0.4 × 0.4 mm, the temporal resolution is increased by use of only 12 steps of rotation and a filtered back‐projection algorithm.
