Investigation of two-stage electrostatic precipitation for silver removal from a helium stream
ENGLISH ABSTRACT: In high temperature gas cooled nuclear reactors various unwanted particles have been found to plate out onto the surfaces of the primary cicuit components. A simple deterministic deflection model is outlined in this paper to describes the deflection of charged silver nanoparticle particles in helium using the principle of electrostatic precipitation. An apparatus, consisting of a charging region and collection region, as in the case of two-stage electrostatic precipitators, was built to validate the applicability of the model. Not withstanding its simplicity, it showed that it is able to favourably capture the experimentally determined particle deflection trajectories.
