Research activities:
NRG scientific and technical programme in fusion technology:

• Irradiation and characterization of fusion reactor relevant structural materials and subassemblies;
• Post-irradiation and reference mechanical testing of various grades of austenitic stainless steel, fasteners, and ferritic/martensitic low activation steels, including fracture mechanics;
• Investigations on advanced materials manufacturing and joining technologies, like EB-welding and HIP-technologies;
• Investigation of the reweldability of irradiated stainless steel for ITER and (re)weldability of ferritic/martensitic low activation steels;
• Development of ceramic tritium breeder materials for ITER/DEMO;
• In-pile measurements of tritium breeding materials and blanket submodules;
• Post-irradiation measurements of tritium retention and release;
• Materials research for plasma facing components;
• Design of irradiation capsules and subassemblies (e.g. for irradiation stress-relaxation), nuclear, thermal and mechanical analyses;
• Spectrally tailored irradiations;
• Neutron & gamma dosimetry, spectrum and damage analysis;
• Management of EU Long Term Materials Programme;

Irradiations are performed in the High Flux Reactor (HFR, 45 MW) in Petten.
