The current concept for disposal of higher activity radioactive wastes in England and Wales is a single Geological Disposal Facility for all Intermediate Level Wastes (ILW) and High Level Wastes (HLW) arising from current and historic nuclear operations. In contrast to encapsulation processes, thermal treatment technologies, such as Hot Isostatic Pressing, offer the potential to reduce conditioned and packaged waste volumes due to the removal of entrained water, minimisation of void space and destruction of combustible materials. In this presentation, I will present an overview of recent strategy development in UK thermal treatment of radioactive wastes and discuss illustrative examples of the application of HIP technology to conditioning of plutonium residues, ion exchange materials, and radioactive sludges, relevant to decommissioning activities in the UK and worldwide.
