Abstract: Steam generator of the type comprising within a vertically axed type enclosure a plurality of U-tubes in which circulates a primary liquid and on the outer wall of which flows a secondary liquid, a cylindrical envelope surrounding the said tubes and defining with the inner wall of the enclosure an annular passage, whose lower part is connected to the inner space of the envelope, the latter being sealed in its upper part by a cover, which is itself surmounted by at least one device for separating the steam by centrifuging, a means for drying the steam in the upper part of the enclosure, said means incorporating at least one steam dryer surrounding the axis of the enclosure, each dryer being connected by its lower part to at least one discharge pipe for removing the water separated from the steam, wherein each discharge pipe is linked with a dynamic draining or bleeding device able to produce a pressure reduction or vacuum in order to suck in the water collected in the dryer. As a result, it is not necessary to maintain a clearance level or height in the discharge pipe.The steam generator is more particularly intended for use in pressurized water nuclear reactors.

Abstract: The present invention relates to a double barrier heat exchanger between a radioactive primary fluid and a secondary fluid making it possible to detect a possible primary fluid leak in the exchanger. The primary fluid circulates in a primary duct and the secondary fluid circulates in a secondary duct, a junction matrix being positioned between the primary and secondary ducts and in contact with the latter. The matrix is in the form of a compact metallic mass incorporating at least one element, e.g. silver, which can be made raidoactive when it diffuses into the primary fluid. Application is to sampling circuits in nuclear reactors.

Abstract: Apparatus for the separaton of the liquid and vapor phases of a fluid incorporating an open ended cylinder in which are arranged blades. Each blade is in the form of a curvilinear triangular surface, whereof a first side contiguous with the cylindrical wall of the cylinder defines a helix whose axis coincides with the cylinder axis, an apex opposite to said first side is arranged substantially at the axis and the remaining sides define a leading edge substantially perpendicular to the cylinder axis and a trailing edge inclined with respect to said axis. A number of blades are joined together at their apices to define the blade arrangement within the cylinder.The invention also relates to a steam generator having an outer casing, a first circuit in which circulates a hotprimary fluid and a second circuit in which circulates a secondary fluid, whereby the latter incorporates at least one group of two separation apparatuses connected in series.

Abstract: Each heat-exchange bank consists of at least two groups of flat, adjacent compartments provided for the circulation of a second fluid and separated by spaces for the circulation of a first fluid. Each compartment has lateral extensions placed in identical and opposite manner in two adjacent groups. The extensions are connected respectively in each group to a common admission manifold and to a common discharge manifold for the second fluid.

Abstract: In a tube-type heat exchanger which produces superheated steam directly while being of the once-through type, the tubes permit recycling of the vapor of the secondary fluid which is circulated within them. A coaxial sleeve mounted within the annular space between an intermediate tube and the pressure tube delimits an annular zone filled with heat-insulating stagnant vapor so as to isolate the vapor produced from the fluid in liquid phase.
