“…This can be because it was the fuel that failed, or because the failure could have a profound effect on the fuel. Similar to the work carried out in Jonkmans et al (2010Jonkmans et al ( , 2013, described earlier, muons can be used to visualise nuclear fuel materials [Sugita et al (2014)]. This method can be particularly useful for accident scenarios such as those found in Fukushima after the 2011 nuclear disaster.…”

“…Jonkmans et al (2010Jonkmans et al ( , 2013 look into the feasibility of using muons to produce tomograms of spent fuel inside containers. Simulations are used to create images using Point of Closest Approach (POCA), Maximum Likelihood Expected Maximisation (MLEM) [Bruyant (2002)], and Scattering Density Estimation (SDE) reconstructions.…”

“…Research has been undertaken to quantify hydrogen take up in zircalloy after simulated LOCA conditions. Naturally, this was done with neutrons due the differing attenuation of neutrons during hydrogen and zircalloy interrogation [Grosse et al (2008[Grosse et al ( , 2011a[Grosse et al ( , 2011b[Grosse et al ( , 2012[Grosse et al ( , 2013; Jenssen et al (2014)]. In the cited work carried out by Grosse, hydrogen uptake is calculated by measuring the attenuation and using the H/Zr ratio.…”

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.

We performed tomographic investigation of the most heavily perturbed (thus highly radioactive) rod and its pristine/unirradiated replicate from the target No. 12 of the Swiss neutron spallation source (SINQ). The tomographic dataset reveals the 3D re-distribution of the lead filling inside the irradiated Zircaloy tube. The change in the linear attenuation coefficient of both the lead filling and the Zircaloy tube of the irradiated rod (due to the presence of the entrapped spallation products) in comparison with the pristine/unirradiated material is quantified. The dataset provides valuable input for the enhancement of safety and efficiency of future spallation targets at SINQ.
