"Experiments on the ADS Innovative nuclear reactor target at Politecnico di Torino" The study of the fluid dynamics of the windowless spallation target of an Accelerator Driven System (ADS) is presented. Several target mockup configurations have been investigated: the first one was a symmetrical target, with two concentric cylinders, the other configuration is not symmetrical. The experiments have been carried out with water simulating the liquid lead-bismuth eutectic at room temperature and at flow rate up to 24 kg/s. The fluid velocity components have been measured by means of ultrasound probes. The velocity field values of the liquid within the target region either for the axial-symmetrical configuration or for the not symmetrical one as a function of the flow rate and of the initial liquid level are presented.

The prediction has been used recently to design a new target geometry that allows to obtain a more appropriate velocity field in the target region.

Abstract

"Experiments on the ADS Innovative nuclear reactor target at Politecnico di Torino" The study of the fluid dynamics of the windowless spallation target of an Accelerator Driven System (ADS) is presented. Several target mockup configurations have been investigated: the first one was a symmetrical target, with two concentric cylinders, the other configuration is not symmetrical. The experiments have been carried out with water simulating the liquid lead-bismuth eutectic at room temperature and at flow rate up to 24 kg/s. The fluid velocity components have been measured by means of ultrasound probes. The velocity field values of the liquid within the target region either for the axial-symmetrical configuration or for the not symmetrical one as a function of the flow rate and of the initial liquid level are presented. A comparison of experimental data with the prediction by a finite volume CFD code is presented too. The prediction has been used recently to design a new target geometry that allows to obtain a more appropriate velocity field in the target region.
