A device for the production of sol-gel globules for sphere-pac nuclear fuel includes a vertical gelling column opening into an elongated vat through its bottom wall, the vat receiving a horizontal gelling stream issuing from a ribbon nozzle. The bottom wall of the vat declines from the gelling column at one end thereof toward an outlet at the opposite end. A sol-liquid feed device is capable of optionally delivering sol-liquid droplets onto a vertical gelling stream produced in the gelling column, while the ribbon nozzle is closed, for the production of a coarse globule fraction, and is capable of delivering fine sol-liquid jets onto the horizontal gelling stream, with the gelling column closed for the production of fine globule fractions. When operating with the vertical gelling stream, the vat serves as an overflow for superfluous gelling liquid, and during operation with the horizontal gelling stream, the gelling column serves as a safety overflow. Because of the combination of vertical and horizontal gelling streams made possible by the collecting vat, the device is of compact design, and requires little space while operating efficiently and safely.
