摘要： A gas-cooled nuclear reactor, having a tight connection with an intentionally provided leak site between a fission-gas discharge channel formed in a reactor core carrying plate as well as in a head portion of encased fuel elements that are suspended in receiving bores formed in the core carrying plate, the tight connection being formed by an annular member having a sealing surface engaging the core carrying plate at a region thereof in which an opening to the fission-gas discharge channel formed in the core carrying plate is located, a gas-tight, elastic and substantially cylindrical member, variable in length, connecting the annular member to the fission-gas discharge channel formed in the head portion of the fuel element, compression spring means biasing the annular member in a direction away from the fission gas discharge channel formed in the fuel-element head portion, and a sealing abutment plate secured to a central pin and limiting clearance for play of the annular member with respect to an annular zone thereof disposed within the sealing surface of the annular member, the leak site including a radial bore formed in and extending through the annular member between the annular zone and the sealing surface of the annular member.

摘要： The individual fuel rods of a fuel assembly are connected to a fission gas exhaust system via perforated end caps. For this purpose, the perforated end caps are provided with external threads and screwed into a rod holding plate of the fuel assembly. In addition to the attachment thus provided, a tight connection to the canals of the fission gas exhaust system, which are built into the rod holding plate, is accomplished thereby at the same time.
