Thermo-shock, experiments and simulations

Your tasks

The main goal in PROACTIV II is the evaluation of the lifetime and structural integrity of the primary cooling circuit of nuclear systems, as they exist in the Swiss context. In Subproject-II, we are currently performing thermal shock experiments on the selected cylindrical mock-ups. In the following two years, samples will be used to observe the crack initiation, propagation and arrest behavior. Validation of the XFEM calculations for crack propagation and arrest will be performed. Improvements of the experimental set-up as well as in-situ monitoring will be done to obtain accurate information of the crack propagation process. It is expected that the understanding of the initiationpropagation- arrest of defects in embrittled RPV steel will be enhanced.

  • Carry out experiments in the thermo-shock facility
  • Prepare samples
  • Collect experimental data and include data in the database
  • Investigate samples with optical microscope and SEM
  • Document the experiments and FE simulations in Abaqus

Your profile

  • Master student in the field of mechanical engineering, material science or similar (Master should not have been completed)
  • Good understanding of fracture mechanics and material damage. Basic knowledge on simulation with FEM
  • Proficiency in English is a prerequisite
