摘要: A tool for chip-removing machining includes an insert holder and an insert that is mechanically connected with the holder via upper and lower interfaces. Each interface includes a pair of contact surfaces that extend at an obtuse angle relative to each other. Disposed centrally between one of those pairs of contact surfaces is a ridge, and disposed centrally between the other pair of contact surfaces there is a flute. Each of the recess and flute is defined by side surfaces that extend at an acute angle relative to each other. When the ridge engages the flute, a proper absorption of transverse forces acting upon the insert is guaranteed, whereby the insert is maintained essentially immovable in its position in order to guarantee a proper machining accuracy.

摘要: In a nuclear fuel rod a cladding tube is provided having a closed inner space and manufactured from at least one of the materials in the group zirconium and a zirconium-based alloy, and a pile of nuclear fuel pellets arranged in the inner space in the cladding tube. The nuclear fuel pellets fill part of the inner space. A fill gas is arranged in the closed inner space 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 that is greater than 3 volume percent of the fill gas or greater than 2 volume percent of the fill gas.

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.
