摘要： A fuel channel (5) for a fuel element (1) to a fission reactor, where the fuel element comprises an inlet (9), an outlet (11) and a plurality of elongated fuel rods (3), which fuel rods each comprises a nuclear fuel and are adapted to transfer energy to a streaming medium during operation of the fission reactor. The fuel channel comprises a casing (7) adapted to surround the fuel rods between the inlet and the outlet. The casing is adapted during operation of the fission reactor to guide the streaming medium along the fuel rods from the inlet to the outlet and be subjected to irradiation from the fuel rods. The casing is manufactured from a ceramic material.

摘要： A fuel assembly for a nuclear boiling water reactor is provided. The reactor comprises a plurality of such fuel assemblies and a plurality of control rods. Each control rod is insertable between the fuel assemblies. The fuel assembly has a longitudinal center axis and includes a plurality of elongated fuel rods and an elongated channel box. The channel box has inner sides, facing the fuel rods, and outer sides. Each inner and outer side has a longitudinal center line extending in parallel with the center axis and along the length of the channel box. A number of protrusions are distributed along the center line of at least two of the outer sides. The protrusions are configured to ensure a minimum distance between the outer side and an adjacent control rod and to enable the control rod to easily slide over and on top of the protrusions.

摘要： A method of producing a cladding tube for nuclear fuel for a nuclear pressure water reactor includes forming a tube which at least principally consists of a cylindrical tube component of a zirconium-based alloy, where the alloying element, except for zirconium, which has the highest content in the alloy is niobium, wherein the niobium content in weight percent is between about 0.5 and about 2.4 and wherein no alloying element, except for zirconium and niobium, in the alloy, has a content which exceeds about 0.2 weight percent. The cladding tube is then annealed such that the tube component is partly but not completely recrystallized. The degree of recrystallization in the tube component is higher than about 40% and lower than about 95%. A fuel assembly for a nuclear pressure water reactor also has a plurality of such cladding tubes.
