There are tens of thousands of waste packages stored on nuclear sites across the world. Containing various materials with various degrees of contamination and activity, spanning the last 6 decades of nuclear reprocessing or decommissioning activities, these containers can vary in size, shape as well as condition. Often, these wastes might have evolved over time, with various effects including potential container expansion or deformation, accelerated corrosion... with a direct impact on the safety and security of the materials within.

With decommissioning accelerating across the world, it is important to confirm the waste behaviour and its potential impact on the performance of the waste container. The implementation of smart packages and sensors is hence essential to monitor this nuclear legacy as well as the thousands of new packages that will appears over the next decades.
