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.


The 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 AREVA NP's Filtered Containment Venting System (FCVS).
