Document Type and Number:
Japanese Patent JP2004513353
Kind Code:
A
Abstract:
The present invention relates to a fuel assembly (10) and a tubular element (32, 32') for a nuclear boiling water reactor. The fuel assembly (10) comprises a plurality of full-length fuel rods (14), at least one part-length fuel rod (15) and at least a tubular element (32, 32'), which is arranged above the part-length fuel rod (15) in the fuel assembly (10). A cooling medium flows, during the operation of the boiling water reactor, upwardly through the fuel assembly (10) in order to cool the fuel rods (14, 15). A part of the cooling medium flow is guided into the tubular element (32, 32') through at least one inlet opening (34, 34') and out through at least one outlet opening (36). The tubular element (32, 32') comprises in the vicinity of the outlet opening (36) an internally arranged body (44, 46) having a surface (38), which deflects at least a main part of the upwardly directed cooling medium flow in the tubular element (32, 32') out through the outlet opening (36) and in a direction towards a full-length fuel rod (14).
