Smaller and Safer Disposal & Storage of Radioactive Waste

The principles of disposal are the isolation of radioactive waste from the society, to delay radionuclide releases and allow them to decay out, by means of multiple barriers. The engineered barrier systems are to prevent and delay the release of radionuclides to the host rock, but its complex interactions with environments require further attention. Corrosion and dissolution of waste forms and canisters are consequences of very complex multi-physics and multi-component environments.
