摘要:
The invention relates to energy mechanical engineering and can be used in power installations involving a liquid-metal heat carrier. A mass transfer apparatus including a housing and, provided therein, a flow reaction chamber filled with a solid-phase granulated oxidation agent, and an electric heater positioned in the reaction chamber. The housing of the apparatus is equipped with a repository for reserves of the solid-state granulated oxidation agent, said repository being located below the reaction chamber and being made in the form of a cup having a bottom, said cup being connected to the reaction chamber. The technical result consists in extending the operational duration of the mass transfer apparatus.

This invention generally concerns radioactive decontamination of deposits on components in a nuclear power plant and is specifically concerned with improved compositions, systems and methods for disrupting, dissolving, removing and reducing at ambient temperature radionuclides formed on the primary side surfaces of components in a pressurized water reactor and the internal components of a boiling water reactor. The methods include identifying the structure, taking the structure out of operational service, contacting the structure with an aqueous solution (e.g., a recirculating flow or static immersion), and adding an effective amount of elemental metal in solid form to the aqueous solution.

Die Erfindung betrifft Kondensationskammerkühlsystem, umfassend eine Kondensationskammer (42) für einen Siedewasserreaktor (46) und wenigstens einen außerhalb der Kondensationskammer (42) angeordneten Wärmetauscher (48). In der Kondensationskammer (42) ist ein längliches Kühlmodul (10, 54) vorgesehen, welches in seinem oberen Bereich einen Verdampfungsraum (12) umfasst, wobei das Kühlmodul (10, 54) derart in der Kondensationskammer (42) angeordnet ist, dass der Verdampfungsraum (12) oberhalb eines Höchstfüllstandniveaus (14) der Kondensationskammer (42) befindlich ist. Das Kühlmodul (10, 54) umfasst fernerhin wenigstens ein Steig- (18) und ein Fallrohr (20), welche mit ihren jeweiligen oberen Enden in den Verdampfungsraum (12) münden und mit ihren jeweiligen unteren Enden in der Kondensationskammer (42). Eine erste Druckleitung (56) ist vom Verdampfungsraum (12) zum Wärmetauscher (48) vorgesehen und von dort eine zweite Druckleitung (58), welche in der Kondensationskammer (42) unterhalb des Mindestfüllstandsniveaus (16) mündet. Somit ist durch die Kondensationskammer (42), die Druckleitungen (56, 58), das Kühlmodul (10, 54) und den Wärmetauscher (48) ein passiver geschlossener Kühlkreislauf gebildet.

Method for controlling the introduction of zinc to a nuclear power reactor to control radiation build-up wherein zinc ions are introduced into the reactor water to counteract loss of zinc within the reactor system. In the process, the rate of introduction of zinc ions into the reactor water is balanced with the rate at which zinc ions are lost from the reactor.

The invention relates to a device for cooling inert emergency protection atmospheres and for separating and eliminating hydrogen, comprising a cooling device (6) for cooling a mixed gas flow. The aim of the invention is to provide a means of drying the hydrogen and also separating heavy, non-condensable gases and solid suspended particles. To this end, a device (7) for guiding and steadying the flow is provided downstream from the cooling device (6). Said device (7) has at least two layers (7a, 7b). The cooling device (6) and the layers (7a, 7b) extend downwards at an angle in the mixed gas flow and the layers (7a, 7b) extend essentially over the entire surface and have openings.
