UNSW Nuclear Innovation Centre
This project aims to synthesise new materials for the nuclear industry, prioritising stability under radiation, thermal, pressure, or a combination of these factors. While materials are often tested for thermal and pressure stability, their radiation tolerance is frequently overlooked. The project looks to provide a basis so that thermal and pressure-stable materials can be tested for radiation tolerance.
Neutron scattering experiments are key to understanding thermal and pressure stability. Variable temperature and pressure neutron scattering tests provide a foundation for further radiation-based studies.
An example of the team’s work in this space is the discovery of zero thermal expansion materials, now being evaluated for pressure stability. These zero thermal expansion materials show no volume change over wide temperature ranges, some from 4 to 1400 K.
