摘要： Systems passively eliminate noncondensable gasses from facilities susceptible to damage from combustion of built-up noncondensable gasses, such as H2 and O2 in nuclear power plants, without the need for external power and/or moving parts. Systems include catalyst plates installed in a lower header of the Passive Containment Cooling System (PCCS) condenser, a catalyst packing member, and/or a catalyst coating on an interior surface of a condensation tube of the PCCS condenser or an annular outlet of the PCCS condenser. Structures may have surfaces or hydrophobic elements that inhibit water formation and promote contact with the noncondensable gas. Noncondensable gasses in a nuclear power plant are eliminated by installing and using the systems individually or in combination. An operating pressure of the PCCS condenser may be increased to facilitate recombination of noncondensable gasses therein.

摘要： A method and a system for catalytic recombination of hydrogen, which is carried in a gas flow, with oxygen, has the gas flow passed through a reaction zone with a number of catalytic converter elements, with steam being added to the gas flow before it enters the reaction zone. The method and system ensure a particularly high operational reliability of the recombination device, even in varying operating conditions or with varying operating methods, in particular with regard to a hydrogen feed, which is provided as required, in the steam/feed water circuit of the installation. For this purpose, the feed rate of the steam to be added is adjusted in dependence on a measured value which is characteristic of a current actual temperature in the reaction zone.

摘要： In the boiling water nuclear plant of the present invention, a steam dryer is disposed in a reactor pressure vessel. Materials that have capability of capturing nitrogen compounds containing N-16 are supported on porous member. The porous members are placed in a region where steam goes through in the steam dryer. For example, both or either of perforated plates installed in the steam dryer is constituted of the porous member on which N-16 capture material is supported. When steam containing N-16 goes through the perforated plates, the N-16 is captured by the porous member, whereby the N-16 transfer amount into the turbine system is reduced.

摘要： A safety system for a nuclear plant includes a plurality of catalytic recombiner elements each triggering a recombination reaction with oxygen when hydrogen is entrained in an onflowing gas flow, so that reliable elimination of the hydrogen from the gas mixture is ensured with an especially high degree of operational safety even based on comparatively extreme conditions or scenarios of the aforementioned type. The recombiner elements and/or the flow paths each connecting two recombiner elements on the gas side are configured in such a way that a pressure pulse triggered in the gas medium by an ignition during the recombination reaction in a first recombiner element triggers a gas displacement process having a flow rate of at least 5 m/s in the onflow region of a second, adjacent recombiner element. A nuclear plant with a safety system is also provided.

摘要： An apparatus for removing hydrogen from a mixture of gases containing hydrogen, oxygen, steam, and aerosols, with a catalyst arrangement composed of a substrate coated with a material which catalyzes the oxidation of hydrogen while releasing heat. The apparatus is characterized by a protective device which encloses a catalyst arrangement until a preset temperature is reached. Once the preset temperature is reached, the apparatus is automatically movable into a position which exposes the catalyst arrangement, with the protective device being permeable to gas pressure but essentially impermeable to aerosols. Consequently, the catalyst arrangement is protected against deposition of aerosols contained in the gas mixture until the preset temperature is reached.

摘要： An exhaust gas recombiner for restoring hydrogen and oxygen gases in gases extracted from a condenser of a steam engine into water by reaction of the hydrogen and oxygen gases includes a vertical cylinder vessel having an extracted gas inlet at its lower end and an outlet at its upper end. A diameter of the vessel is substantially the same as that of an outlet piping connected to the outlet of the vessel for introducing gases leaving the vessel into an exhaust gas condenser. The apparatus further includes a plurality of units in the vessel. Each unit has a honeycomb structure for flow-rectifying gases flowing into the vessel through the extracted gas inlet and a honeycomb catalyst gas carrying on its surfaces a catalyst being positioned on an upper side of the honeycomb structure.
