Research Fellow (Nuclear Engineering)

Job Description

The candidate scope of work includes the following main areas of responsibility:

  • Perform both steady-state and accident radiological source term evaluations of different event scenarios for high-temperature gas-cooled reactor (HTGRs)
  • Participate in the development and validation of computational models and tools used in source term analysis
  • Study and model the effects of particulate matter on fission product transport behaviour
  • Develop models to evaluate fission product lift-off, plate-out and circulating coolant activities within the primary circuit
  • Assist in the analysis of fission product release from kernels and transport through fuel coatings in defective particles for accident scenarios
  • Support post-processing and data interpretation to inform safety case development and risk quantification
  • Collaborate on the development of an in-house integrated multi-scale source term analysis framework for HTGRs
  • Document results and provide technical inputs to related projects and cross-functional teams
  • Prepare technical reports and presentations for agencies and industrial partners

Qualifications

  • Minimally PhD in nuclear engineering or a related field or demonstrated experience in radiological source term analysis
