Risk Assessment led Design of ODS Steels for Gen-IV Nuclear Reactors

  • Full or part time
  • Application Deadline

  • Funded PhD Project (Students Worldwide)
    Funded PhD Project (Students Worldwide)

Project Description

The Oxide Dispersion Strengthening (ODS) Steels are candidate material for cladding, tubing, and the blanket of high-temperature Gen-IV nuclear reactors. The ODS steels provide high resistance against irradiation, creep, and swelling without considerable degradation of their material properties. The yttrium oxide nanoparticles in ODS steels trap the radiation-induced point defects and helium bubbles and transform to new complex oxides. The low cycle fatigue (LCF) during start-up/ shutdown of reactors and creep-fatigue interaction in the service life produce material embrittlement.

This project will develop the mechanistic data of irradiation and thermal ageing led deformation of the ODS steel and nanoparticles to underpin their design methodology for long term nuclear reactor life cycle. The parametric study of the effects of different combinations of irradiation and thermal loads on the stability of nanoparticles and mechanical properties will be used to develop a risk assessment led design methodology of the ODS steels in the nuclear reactor life cycle.

The stability of nanoparticles in the nuclear-irradiated environment will be used to underpin the safe life of the structure materials and develop a proactive risk mitigation framework preventing unexpected failures in the nuclear reactor life cycle to assist regulatory, compliance and safety standards for translation of nanotechnology in the nuclear energy production supply chain.

Training and Development

The successful candidate will receive comprehensive research training including technical, personal and professional skills.

All researchers at Coventry University (from PhD to Professor) are part of the Doctoral College and Centre for Research Capability and Development, which provides support with high-quality training and career development activities.
