Legacy Ponds and Silo Wastes

Building on previous surrogate trials using thermal methods such as plasma vitrification and joule heated in-can vitrification this project will aim to understand the corrosion mechanisms in the resulting heterogeneous wasteforms. We will use a combination of durability testing and modelling across length scales to examine the impact of local equilibria on corrosion at different locations in the microstructure. The ultimate aim is to provide sufficient understanding to underpin safety case for storage and disposal of Sellafield’s legacy pond and silo wastes.
