Contribution of IRSN R&D to reducing the risks of airborne pollutants dispersion during the dismantling of nuclear facilities

Abstract

International audienceThis paper presents a general overview of IRSN research activities for assessing and reducing the risksof airborne dispersion of radioactive contamination during the dismantling operations of nuclearfacilities. Four main topic areas are addressed: aerosol source term, contamination transfers, behaviorof containment equipment and contamination metrology. Firstly, the various experimental and numericalmeans involved are presented
