inside Nuclear

Techniques such as non-destructive 3D computer tomography let us look inside the interior of objects to determine how the different components work together.

This imaging project explored the internal structure of Tristructural-isotopic (TRISO) fuel micro particles for a variety of applications using X-ray Computer Tomography. We used imaging technology so that we might better understand the processes that take place within nuclear reactors.

Work undertaken at the Henry Mosley X-Ray Imaging Facility has explored this area by examining the interior structure of TRSIO fuel particles. From images like those pictured opposite we have observed how the four layers of the fuel particles interact to safely contain nuclear material in a reactor and produce low hazardous waste. TRISO particles are a safer, more efficient, next-generation nuclear fuel and the work from this project has been used to characterise the different types of micro particles.
