Technical Meeting on Structural Materials for Heavy Liquid Metal Cooled Fast Reactors

The compatibility of structural materials, such as steels with lead and lead-bismuth eutectic (LBE), poses a critical challenge in the development of heavy liquid metal (HLM) cooled fast reactors. Factors such as very high temperature, high fast neutron flux, high irradiation exposure and corrosiveness provide a severe environment for materials in these advanced reactor systems. The compatibility of liquid coolant with structural materials is critical for the development of innovative nuclear energy systems. Their safety, feasibility and optimization depend on the capability of the selected materials to withstand the expected operating conditions.

The purpose of the event is to discuss experiences and the latest innovations and technological challenges related to structural materials proposed for innovative reactors cooled by lead and lead-bismuth eutectic.

The event consists of five sessions addressing the following topics:

1. HLM compatibility with structural materials: phenomena, modelling and operational experience;
2. Corrosion mitigation measures: coating and surface engineering, and environmental conditioning, etc.;
3. Development of structural materials resistant to HLM corrosion;
4. HLM structural Materials and Coatings under Irradiation: Testing and characterization, and impact of neutron-induced radiation damage, etc.; and
5. Qualification Programmes of Structural Materials for HLM Fast Reactors.
