Alternative materials for encapsulation of nuclear waste in a net zero world

The National Nuclear Laboratory (NNL) is seeking game changing encapsulation solutions that are more fitting for a future Net Zero world. 

Cement based materials are used extensively for the encapsulation of a wide variety of low and intermediate level radioactive wastes. However lower alkalinity alternatives are being explored to reduce corrosion of encapsulated metals. These alternatives also offer environmental benefits due to their lower carbon footprint. Additionally, alternatives are being sought to ensure security of supply.

Current cement-based systems require considerable energy to produce and release CO2 in their production. In light of the UK Net Zero 2030 targets, there is a requirement to be even more ambitious. This challenge seeks novel solutions to more sustainable materials.
