LWR aerosol experiments at victoria model containment

The behaviour of radioactive aerosols in the LWR containment during a hypothetical core melt accident is an important factor determining the possible releases of radioactive materials into the environment (Source Term). During leakage or containment failure the Source Term is directly related to the concentration of radioactive aerosols in the containment atmosphere. The aim of aerosol experiments in the VICTORIA facility is to validate the containment aerosol models used in the nuclear reactor accident codes. As a final goal we need to confirm that containment aerosol codes are able to calculate correctly the radioactive hygroscopic and non-hygroscopic aerosol behaviour in non-homogeneous multicompartment containments. It is possible to reach this goal by making experiments in the well controlled and instrumented model containment (VICTORIA multicompartment test facility, Loviisa Nuclear power station model containment with linear scaling 1:15).
