A METHOD OF FABRICATING A URANIUM TARGET FOR PRODUCING MOLYBDENUM, A PROCESS OF PRODUCING MOLYBDENUM, AND A URANIUM TARGET FOR PRODUCING MOLYBDENUM

摘要

A method of fabricating a target (200) with predetermined mass and volume from low-enriched uranium, in which the fabrication step (102) is carried out in an additive process by applying successive layers of the construction material and selectively heating by means of a laser, according to the invention is characterized in that prior to the fabrication of the target (200), a digital model of the target (200) with dimensions substantially matching the dimensions of the container is created, the model defining an openwork cohesive body filling the container with margins. A process of producing molybdenum 99 comprising a step of fabricating (102) a target (200) from a construction material containing low-enriched uranium, a step of packing (103) the target (200) into a container, a step of irradiating (104) by placing the container with the target (200) in a reactor followed by an unpacking step (105), a transport step (106), and a step of chemical treatment (107) of the target for obtaining molybdenum 99, according to the invention is characterized in that the step of fabricating (102) a target is performed using the method according to the invention. The invention concerns also the target (200) having an openwork structure with voids.
