The ingress of liquid water into the primary circuit of HTRs with steam cycle can pappen in special accident scenarios That involves dependant on the mass of water in the primary circuit reactivity effects which have to be prevented absolutely. In order to show the inherent safety effects it must be proved that also in case of severe water ingress accidents catastrophic consequences can not occur. The further aim must be to show the inherent or passive acting safety characteristics of the HTR to prevent the ingress of liquid water into the core. Therefore the flow channel SEAT was installed at the Institute of Safety Research and Reactor Technology of the Research Centre Jülich. The -Lest facility can be operated in closed as well as in open cycle. Main goal of the experiments are the research of the movements of water droplets and their distribution in relevant sections of the gas flow in HTRs as well as the separation of water droplets fror the gas flow. The experimental programmes were planed and the test facility was drafted, constructed and was put into operation together with the measurement technique. In order to measure the droplet spectra a particle size measuring device based on the principle of laser diffraction was bought. In the following several experiments were realised using various flow geometries. In addition various droplet separation components were tested . Finally the resuhs are transferred to HTRconditions. |
