Postdoctoral Fellow in Nuclear Fuel

Microstructural characterization and stresses at fuel cladding interfaces

Your tasks

  • Investigate the influence of stresses from the fuel pellet onto the cladding and of outer cladding deposits (CRUD)
  • Evaluate the role of the stresses for the formation, distribution and change in morphology of hydrides in the cladding
  • Prepare fuel/cladding specimens using conventional FIB cut process
  • Apply experimental methods of interest, in cooperation with PSI hotlab – metallography, Electron Probe Micro-Analyzer (EPMA), FIB and FIB-based Electron Backscatter Diffraction (EBSD), synchrotron XRD and/or XAS, and/or neutron radiography
  • Publish your results in renowned scientific journals and report at international conferences

Your profile

  • PhD degree in Materials Science, Physics or Chemistry
  • Prior experience with at least one of the following techniques is required: FIB, EBSD, synchrotron based techniques (XRD, XAS) and knowledge on data analysis methods (stress/strain determination)
  • Experience with handling radioactive materials is a big plus
  • Good knowledge of English, knowledge of German is an advantage
  • First experience in project management
