The present paper presents an experimental method to measure velocity fields in a cavitating flow. Dynamics of the liquid phase and of the bubbles are both investigated. The measurements are based on ultra fast X-ray imaging performed at the APS (Adv

International audience; Cavitation consists of successive vaporization and condensation processes in a liquid flow, due to a large pressure decrease usually associated with sudden flow acceleration. This phenomenon occurs typically in pumps and naval

Radiological characterization of nuclear waste packages is an industrial issue in order to select the best mode of storage. The alpha‐activity, mainly due to the presence of actinides (235U, 238U, 239Pu, …) inside the package, is one of the most

This paper describes a method based on photofission developed in our laboratory to characterize in depth large waste packages. The method consists in using photons of high-energy (Bremsstrahlung radiation) in order to induce reactions of photofission
