摘要： A fuel assembly (1) for a nuclear reactor comprises a bundle of fuel rods (3) with a first group of fuel rods (5a) and a second group of fuel rods (5b). Each fuel rod comprises a cladding tube (15) and stack of fuel pellets (12) enclosed within the cladding tube. At least a main portion (13) of the fuel stack comprises a fissile nuclear material comprising Plutonium and Thorium, and is arranged with an axial hole (22). Said main portion (13) of the fuel stack of each fuel rod (5a) of the first group comprises a first axial hole (22a) constituting a first volume and said main portion of the fuel stack of each fuel rod (5b) of the second group comprises a second axial hole (22b) constituting a second volume. The first volume and the second volume are different.

摘要： The present invention concerns a fuel assembly (12) for a nuclear power boiling water reactor. The fuel assembly comprises fuel rods (23). At least 95% of the fuel rods comprise nuclear fuel material in the form of U enriched in 235 U. At least 20% of the fuel rods belong to a first set of fuel rods (41, 32, 26, 9). The fuel rods in this first set comprise both U enriched in 235 U and Th. The first set comprises a first and a second subset of fuel rods (41, 32). The ratio, with regard to weight, between Th and U, in each fuel rod (41) of said first subset, is higher than the ratio, with regard to weight, between Th and U, in each fuel rod (32) of said second subset. The invention also concerns a nuclear power boiling water reactor and a manner of operating such a reactor.
