Abstract: A method of incineration of minor actinides in nuclear reactors is presented. The minor actinides to be incinerated are embedded in at least one finite region of a core of a thermal nuclear reactor. This finite region is isolated from the rest of the core by means of a thin layer of material that absorbs thermal neutrons but is transparent to fast neutrons. This isolating material is preferably fissile, so that the neutron flux in the core is not simply filtered of its thermal neutrons, but also amplified in its fast neutrons.

Abstract: The invention concerns a monobloc fuel element (10) formed with coated fissile particles, embedded in a matrix such as SiC, inert relative to the fissile and fertile heavy nucleus balance and relative to the coolant flowing in and around said element. Furthermore, the fuel element (10) comprises parallel plates (12) defining spaces (14, 20) between them. The ratio of the thickness (e1, e2) of the plates to the spaces enables to place at will the fuel element in the fast spectrum or in a thermal spectrum. The use of said fuel element in a boiling water and fast spectrum nuclear reactor and operating in natural circulation, wherein said ratio is substantially equal to 1, enables a high plutonium consumption.

Abstract: The present invention relates to a method for extracting the minor actinides from used nuclear fuel. The fuel of the initial load in the core (1) consists of a fuel mixture containing plutonium and aluminium granules, wherein the plutonium is present in an amount ranging from 1 to 2 atomic-percentage % while the balance consists of aluminium. The criticality of the core (1), which decreases together with the fuel depletion in the initial load, is maintained by adding minor-actinide granules in said load. After the plutonium has burnt out, a fuel is produced in the form of a metallic alloy containing minor actinides and aluminium in amounts ranging from 3 to 3.5 atomic-percentage % for the minor actinides and from 96.5 to 3 atomic-percentage % for the aluminium. The fuel composition thus obtained is maintained until the end of the burning process of the accumulated minor actinides. The minor-actinide combustion in the core (1) is compensated with plutonium. After the minor actinides have burnt out, a fuel is produced in the form of a metallic alloy that contains between 1 and 2 atomic-percentage % of plutonium, the balance consisting of aluminium. The composition thus obtained of the fuel in the mixture is maintained until the end of the burning process of the remaining plutonium reserves. This operation method for a fast homogeneous nuclear reactor is used for destroying the highly-radioactive and long-life irradiating products, i.e. minor actinides, in the nuclear fuel. This method also provides for a wider range of construction materials for the vessel (2) of the core (1), and can be used for reducing the accumulated amounts of military-grade plutonium.
