Development of tritium management in fusion and fission facilities

Further research is needed to assess, limit and mitigate impacts of tritium discharges from existing fission installations, temporary storage or spent nuclear fuel repositories and future fusion power plants. Research action[[Funded from fission (33%) and fusion (67%) budget lines]] should include:

1. Modelling activities, assessment of 3D tritium migration, detailed description of permeation transfers through metallic walls, H/Tritium profile in material;
2. Tritium measurement including online measurement in liquid metal, online inventory measurement in tritiated aerosol, in waste and in real configuration;
3. Control of tritium release during operation with reference to the influence of the properties of the surface (oxidation, roughness effect) and of the physical-chemical properties of the interface between different materials in real-life conditions (e.g. during tritium experiments study of co
