摘要： A mixing device for several turbulent streams of fluid (5) at different temperatures and/or of different compositions comprises a mixing chamber (1) for large throughputs and minimal pressure losses, in particular below the reactor core of a gas-cooled high-temperature reactor. The mixing chamber (1) can have a straight, curved and, in particular in high-temperature reactors, a circular median line (2). Several deflecting elements (3) located at a distance apart in the direction of the median line (2) open into the mixing chamber (1). In high-temperature reactor installations in which the heat is dissipated in different radial and/or azimuthal directions, hot and cold strands of gas, even those which issue from unavoidable gaps, are mixed with the main gas stream without endangering the adjacent metallic structural components.

摘要： L'invention concerne un conduit de liaison entre deux appareils fixes assurant la circulation d'un fluide à haute ou à très basse température.
Le conduit de liaison est constitué par trois tronçons rectilignes (1, 2, 3) sensiblement de même longueur, raccordés bout à bout et placés de façon que l'axe de l'un quelconque de ces tronçons soit orthogonal aux axes des deux autres tronçons.
L'invention s'applique, en particulier, au circuit de sodium secondaire d'un réacteur nucléaire à neutrons rapides.

In one embodiment, the steam generating vessel includes a plurality of vertically stacked heat exchangers operable to convert a secondary coolant from a saturated liquid to superheated steam by utilizing heat gained by the primary coolant from a nuclear fuel core in the reactor vessel. The secondary coolant, may be working fluid associated with a Rankine power cycle turbine-generator set in some embodiments. The steam generating vessel and reactor vessel may each be comprised of vertically elongated shells, which in one embodiment are arranged in lateral adjacent relationship. In one embodiment, the reactor vessel and steam generating vessel are physically discrete self-supporting structures which may be physically located in the same containment vessel.

摘要： A fuel channel assembly for a nuclear reactor may include an inner conduit received within an outer conduit that has an outer upper end connectable to a coolant outlet and an outer lower end. The inner conduit may have an inner upper end connectable to a coolant source and an inner lower end axially spaced apart from the inner upper end and disposed within the outer conduit to enable coolant to circulate from the coolant source to the coolant outlet through both the inner and outer conduits. A fuel bundle chamber may be between an inner surface of the outer conduit and an outer surface of the inner conduit and may at least partially laterally surround the inner conduit. The fuel bundle chamber fluidly connecting the inner lower end and the outer upper end to enable the coolant to flow upward through the fuel bundle chamber.

摘要： The invention relates to a nuclear reactor primary circuit comprising a primary pipeline (30), which defines an internal volume (32) and in which a primary nuclear reactor coolant downwardly runs, an additional pipeline (26) which is branched to the primary pipeline (30) and defines an internal volume communicating with the internal volume (32) of the primary pipeline (30) and a cuff (36) whose first end (50) is connected to the additional pipeline (26) and the second free end (52) is positioned in the internal volume (32) of the primary pipeline (30). According to said invention, the second end (52) is delimited by a free peripherial edge (53) comprising at least one upstream and downstream sections (56, 58) which are oriented towards the upstream, wherein the upstream section (56) penetrates into the internal volume (32) deeper from the primary pipeline (30) than the downstream section (58).
