Radioactive aerosol deposition and the assessment of its resuspension during a design basis accident (DBA) in the primary circuit have been revealed in the past as a key issue in the development and certification of advanced pebble bed High Temperature Reactors (HTRs). The report describes the particle parametres to be expected. Actual CFD methods to model particle deposition and particle resuspension are reported.
