摘要

In the course of their reprocessing, the irradiated nuclear fuels are sheared, and then dissolved in a nitric solution is hot, which is then decanted into a clarifier (10). According to the invention, the fine of dissolution is collected at the bottom of the clarifier are broken up before being transferred on a site for the vitrification. For this purpose, it directs the fines to a transfer vessel (16), then circulates in a loop (20) comprising a pump (24) and a device (26 dilacérateur). Finally, the transfer towards the site of the vitrification is carried out by passing through an of fines (30), for example ultrasonic. The device dilacérateur (26) may be an ultrasound, to the venturi tube, or to the venturi tube and a system of baffles. A prior shredding can be made to the inside of the clarifier (10).
