Abstract: A system for removing the residual power of a pressurized water nuclear reactor, includes a reserve of water, a steam generator, wherein the primary water heated by the core either circulates in a forced manner during power operation, or circulates naturally when the primary pump is stopped, and a condenser housed in the containment vessel. The condenser includes a recovery unit for recovering the condensed water and a condenser link to ensure the circulation of water in a closed circuit between the reserve and the condenser. The system further includes a device for circulating the secondary water between the steam generator and the condenser, the device being activated without an external supply of electrical energy, when an operating parameter characteristic of excessive heating of the primary water reaches a certain threshold, such that the primary water heated by the core and circulating in the steam generator vaporizes the secondary water.

Abstract: A system for producing and distributing electrical energy over an electrical network of a geographic area, includes a first entity for generating electrical energy, which operates in a steady state and generates at least a portion of the electrical energy; a second entity for intermittently generating the electrical energy from renewable energy; a third entity, which is capable of operating in a load-following state, the system being sized such that the profile of the change in total energy potential of the geographic area over the span of one year, corresponding to the sum of the profile of the change in the amount of electrical energy distributed by the main entity and the profile of the change in the amount of electrical energy generated by the second entity over the span of one year, is less than the profile of the change in the demand for electrical energy of the network.

Abstract: The system according to the invention prevents the effect of turbulence due to exhaust of gases via chimney from propulsion machines on aircraft carriers (1). It consists of creating internal circulation of water by means of a scope (3) of a circulation pump (4), an inlet chamber (6) in which exhaust gases from the thermodynamic machines of the Ship empty. Water nozzles are placed in this inlet chamber (6). The resulting mixture is evacuated via a pipe (7) and a mixing tube (8) terminating outside the ship, to the stern thereof, just above the water line. Application to aircraft carriers.

Abstract: The balancing device makes it easy to balance low and medium tonnage ships without needing to use high power. It comprises mainly one or several trains of moving masses mounted on a U track of which the side branches are parallel to the side walls of the ship, the central segment being perpendicular to the center line of the ship. Two drive wheels placed inside the turning points of the U enable driving of the train of moving mass. Application to low and medium tonnage ships.

Abstract: The device makes it possible to stabilize high tonnage ship, when several of them are used. Mainly, it comprises a train of mobile lead masses (12), completed at each end by a pair of jaws (16) pressing against the lateral rails of a housing (3). A single cable (2) serves to pull the train and to control the release of the jaws (16). The control means for displacement and for cable tension are placed on one side of the ship. The winch (20) of one device can be coupled to the winch of an adjacent device, thus allowing compensation should a device fail. Application refers to the stabilization of high tonnage ships, such as aircraft carriers.

Abstract: The invention relates to a process and an apparatus for the processing or treatment of fluids containing suspended particles and more particularly usable for the processing or treatment of gases and liquids contaminated by radioactive particles.The fluid to be treated undergoes a treatment cycle in the circuit. This cycle comprises a filtering stage performed in the filtering apparatus in order to extract part of the fluid in the purified state and a separating stage performed in the separating device for extracting part of the particles present in suspended form in the fluid. It is possible to commence the processing cycle either by the filtering stage, or by the separating stage. The particle-depleted fluid from the separating stage or the particle-enriched fluid from the filtering stage undergoes a further processing cycle after adding thereto fluid to be treated by means of the pipe.
