The PKL large-scale test facility is used to conduct experiments on the thermal-hydraulic behaviour of pressurized water reactors (PWRs) during operational transients and accidents with respect to:

  • Overall system responses and system interactions
  • Demonstration of safety margins and evaluation of PWR operating procedures for design and beyond-design-basis events.

Moreover, parameter studies and tests focusing on separate effects contribute to:

  • Supply of unique experimental data for thermal-hydraulic system code development and validation
  • Detailed understanding of complex PWR thermal-hydraulic phenomena.


Your benefits

  • Worldwide unique 4-loop test facility for experiments on PWR integral system behaviour
  • Transients and accidents analyses, procedure validation and separate effect tests contribute to solution of PWR safety issues
