Abstract

During the Phebus-FP tests, realistic fission products and aerosols will be introduced into a containment vessel about five thousand times smaller in volume than the containment building of a full scale light water reactor. The time that these fisson products remain airborne depends on the amount of water vapour present in the atmosphere. At high humidities water vapour can condense onto the aerosol particles and enhance their settling. The objectives for the containment vessel are therefore specified in terms of a desired humidity; in order to know how to specify the boundary conditions a series of thermalhydraulic tests will be carried out in the Phebus-FP vessel. This paper describes a set of calculations made by various organisations, using state of the art computer programs, to predict these thermalhydraulic tests.
