摘要： The present invention relates to a control rod for a nuclear plant. The control rod is arranged to be provided in a fuel assembly of the nuclear plant and to be in contact with cooling water. The control rod comprises at least an inner space which is adapted to receive an absorber material for allowing absorption of neutrons during operation of the nuclear plant. The absorber material allows formation of at least one gaseous substance during said absorption process. The control rod comprises at least a filter member having a material structure which allows passage of the gaseous substance out from the space at the same time as the material structure prevents a passage of surrounding cooling water into the space.

摘要： The invention concerns a nuclear fuel rod (1) for a nuclear reactor of the boiling water type or pressurized water type. The nuclear fuel rod comprises a cladding tube (2), that defines a closed inner space (3) and which is manufactured from at least one of the materials in the group zirconium and a zirconium-based alloy, and a pile of nuclear fuel pellets (9) arranged in the inner space in the cladding tube so that the nuclear fuel pellets fill part of the inner space. A fill gas is arranged in the closed inner space in order to fill the rest of the inner space. The internal pressure of the fill gas in the nuclear fuel rod amounts to at least 2 bar (abs) or at least 10 bar (abs). The fill gas contains a proportion of inert gas a proportion of carbon monoxide. The proportion of carbon monoxide is greater than 3 volume per cent of the fill gas or greater than 2 volume per cent of the fill gas.
