Abstract
The invention concerns a vessel for processing, transfer, accumulation and/or transfer of material containing civilian or military origin plutonium, in the form of plutonium oxide, carbide and/or nitride. The plutonium is preferably present in a concentration not higher than a guaranteed maximum between 20 and 50% wt. in said material, possibly with other actinides such as americium, neptunium, or curium. Said material is preferably in form of powder, granulate and/or tablets. The vessel comprises a volume of 20 to 70 liters for containing said material, demarcated at least by two substantially parallel walls, these two walls being separated by a distance e between 8 and 15 cm. The invention concerns also an enclosure comprising analogous geometrically safe criticality-preventing means (bottom-catcher), a fuel production plant comprising a set of such vessels, preferably installed in a set of said enclosures, as well as a nuclear fuel production process carried out in a set of such vessels, preferably installed in a set of said enclosures.
