A precise understanding of the level of radioactivity inside the containment is essential to manage a severe accident or a loss-of-coolant accident (LOCA).


The Post-accident Sampling System (PRONAS) enables representative sampling of containment atmosphere (aerosols, iodine, noble gases).
Analysis of the samples provides details on the containment situation and the core damage state.


Your benefits

  • High-quality sampling, without significant losses and deposition effects
  • Accurate information regarding the radioactivity level in the containment
  • Easy handling of the samples thanks to high dilution factor
  • Capability to derive the damage state of the reactor
