摘要： The invention relates to compositions and methods for coating a zirconium alloy cladding of a fuel element for a nuclear water reactor. The composition includes a master alloy including one or more alloying elements selected from chromium, silicon and aluminum, a chemical activator and an inert filler. The alloying element(s) is deposited or are co-deposited on the cladding using a pack cementation process. When the coated zirconium alloy cladding is exposed to and contacted with water in a nuclear reactor, a protective oxide layer can form on the coated surface of the cladding.

摘要： A novel nuclear fuel element is developed for, in particular, being used in fourth generation gas heat conductor reactors functioning with a rapid neutron flow. While being a composite plate structure, the inventive element (1) comprises a network (6) of cavities (8), preferably with a honeycomb layout, in each of which a nuclear fuel pellet (10) is placed. A radial clearance and an axial clearance are provided inside each cavity (8) in order to compensate for the differential swelling between fissile materials and structural materials inherent to the functioning of the plate (1).

摘要： The invention relates to a fuel element for a pressurized-water reactor comprising a number of fuel rods arranged in a square lattice and wherein certain positions in the lattice contain guide tubes for receiving control rods, wherein the fuel element can be used for higher burnup by manufacturing the guide tubes of the element such that their irradiation-induced growth is reduced and their corrosion resistance is increased compared with conventionally manufactured guide tubes. This is achieved by finally heat-treating the guide tubes in two steps, the first step being a beta quenching and the second step a heat treatment in the alpha-phase region.
