Waste Immobilisation Process Development

NNL has over 25 years' experience providing a waste immobilisation development service. We developed the first industrial ILW encapsulation processes in the world and these are now used around the globe.

Based at our Workington Rig Hall facility and at our Central Laboratory on the Sellafield site, we currently offer services to customers in both cement-based encapsulation processes and high temperature processes. The latter uses hot isostatic pressing to produce ceramic, glass-ceramic and metal encapsulated waste forms.
