Passive Gaseous Effluent Monitoring System – PEGASUS: Determine the Released Radioactivity in the Case of Containment Venting

In the case of a severe accident and the need of a containment filtered venting, radioactive material is released. In order to estimate the impact on the environment, a precise measurement of the released activity is required.

AREVA's Passive Gaseous Effluent Monitoring System (PEGASUS) measures the gamma-ray emission of the released radioactive material and determines the discharged activity as a function of time. Besides beeing designed for severe accident conditions, PEGASUS is a semi-passive system that is operational for at least 72 hours in the case of a station blackout (SBO). It is applicable to all nuclear power plant (NPP) designs in combination with the AREVA Filtered Containment Venting System (FCVS).

Your benefits

  • Precise online information on released activity to the environment
  • Capability for a detailed analysis of single nuclides for an estimation of soil contamination
  • Conservation of evidence for the autority
  • Basis for an early notification of neighboring states according to IAEA
