摘要： A nuclear plant has a containment shell and a pressure relief line passing out of the containment shell and sealed by a shut-off valve, and through which a pressure relief flow can flow during relief operation, such that it is configured for particularly reliable management of critical scenarios where there is a considerable pressure increase within the containment shell at the same time as the release of hydrogen and/or carbon monoxide. A gas flow treatment device is provided upstream from the respective pressure relief line, and contains a flow duct and has a lower inflow opening and an upper inflow/outflow opening. Catalytic elements for eliminating hydrogen and/or carbon monoxide are arranged in the flow duct above the lower inflow opening. During a critical fault, the flow duct is flowed through from bottom to top by a gas mixture present in the containment shell by the principle of natural convection.

摘要： A containment protection system for treating air in a containment of a nuclear facility in the case of accidents involving extensive release of hydrogen and steam is to be able to effectively relieve such conditions in a largely passive manner. Accordingly, the containment protection system has for a circuit, which contains a conduction system and is provided for connecting to the containment, out of the containment and back again for a fluid flow. The system has a recombination device for recombining hydrogen contained in the fluid flow with oxygen to form steam, a condensation device connected downstream of the recombination device for condensing steam fractions contained in the fluid flow with measures for diverting the condensate out of the fluid flow, and a drive device for the fluid flow.

摘要： A device for trapping flammable gases such as hydrogen comprises active means (3) inside a casing (1) which is closed except for openings which are plugged by filters (2) that normally allow only the gases that are to be trapped to pass through them. The trapping maintains a reduced pressure inside the casing, which continually draws in the gases produced outside. The trap can operate without any maintenance and for long periods of time, even in a completely enclosed environment.

摘要： A recombination apparatus is provided to an off-gas system of a boiling water nuclear plant. An off-gas system pipe connected to a condenser is connected to the recombination apparatus. A catalyst layer filled with a catalyst for recombining hydrogen and oxygen is disposed in the recombination apparatus. The recombination catalyst has a percentage of the number of Pt particles whose diameters are in a range from more than 1 nm to not more than 3 nm to the numbers of Pt particles whose diameters are in a range from more than 0 nm to not more than 20 nm, falling within a range from 20 to 100%. The condenser discharges gas containing an organosilicon compound (ex. D5), hydrogen, and oxygen, which is introduced to the recombination apparatus. Use of the above recombination catalyst can improve the performance of recombining hydrogen and oxygen more than conventional catalysts and the initial performance of the catalyst can be maintained for a longer period of time.

摘要： A device and a method for recombining hydrogen and oxygen in a gas mixture, especially for a nuclear plant, includes feeding the gas mixture to a heating chamber through a feed line in which a blower is connected. A control unit associated with the blower is provided to adjust the delivery rate of the blower in accordance with the hydrogen content of the gas mixture. This provides a particularly simple measure for reliably reducing the hydrogen present in the gas mixture, even in different operating states.

摘要： A device for the recombination of hydrogen and oxygen includes catalyst bodies having surfaces and a catalytic coating on the surfaces over which a gas and vapor mixture containing hydrogen to be eliminated is to be conducted. A casing which surrounds and retains the catalyst bodies has at least one permanently open gas inlet aperture and one permanently open gas outlet aperture, and a gas flow path in the casing through which the apertures communicate. The catalyst bodies are disposed downstream of the gas inlet aperture in the gas flow path. The catalyst bodies are flat bodies formed of multi-layered sheet metal in a multi-channel configuration forming a plurality of mutually parallel gas flow channels. Some of the gas flow channels have channel cross sections being defined by at least an adjacent two of the flat bodies being spaced-apart, and the gas flow channels at ends of the configuration have channel cross sections being defined by at least one of the flat bodies. The flat bodies each have a metal support sheet, a porous adhesion-promoting surface structure of the support sheet with a thickness of less than 10 .mu.m, a porous intermediate layer, preferably of Al.sub.2 O.sub. 3, applied to the surface structure for increasing surface area, and a catalyst coating of platinum or palladium being applied to the intermediate layer and distributed finely enough to preserve porosity of the intermediate layer.

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.
