Hydra System Commissioning Study

Paul Scherrer Institute – PANDA Test Facility Studies

  • Analysis of the composition and characteristics of vent streams from a Passive Decay Heat Removal safety system for Advanced Light Water Reactor Systems
  • The development of Passive Protection Systems eliminates sources of failure present for active systems e.g. Human error or power failure
  • The Hydra was commissioned to investigate the function and reliability of passive condensers under severe accident conditions, in presence of “non-condensable” gases e.g. N2, which can markedly affect the efficiency of the PPS
