S18: Mechanical Behavior of Nuclear Materials


With the renaissance of nuclear energy worldwide and the increasing demand in higher operation temperature, longer service life, and stricter safety requirements in advanced fission reactor systems, there is a pressing need to generate an up-to-date understanding of the mechanical behaviour of advanced and novel nuclear materials. Mechanical behaviours, such as stress-strain response, fracture toughness, creep, fatigue are all key elements for the design and life-time assessments of structural nuclear fission components for both in-core and out-of-core applications under both service and off-normal conditions.

For conventional materials, their behaviours must be studied under higher temperatures, severer irradiation conditions and even more corrosive environments; in terms of novel materials produced by different processing and manufacturing processes, the lack of in-service data affects their application to this safety-critical industry. As such, this symposium aims to bring together engineers and scientists from across the world to share their work on nuclear materials and contribute to a safer and cleaner energy generation internationally.

The symposium welcome abstracts in the following topics, but not limited to:

  • Structural materials, metals, ceramics, composites
  • Fuels (metallic, ceramic and composites) and core components
  • Degradation in microstructure and properties due to irradiation, thermal and environmental effects in various reactor systems
  • Novel characterisation techniques including synchrotron radiation, micromechanical testing and lab-based customised designs
  • Mechanistic modelling
