Abstract: A system and a method for injecting hydrogen into Boiling Water Reactor (BWR) reactor support systems in operation during reactor startup and/or shutdown to mitigate Inter-Granular Stress Corrosion Cracking (IGSCC). The system may provide hydrogen at variable pressures (including relatively higher pressures) that match changing operating pressures of the reactor supports systems as the reactor cycles through startup and shutdown modes.

Abstract: The invention relates to a method for purifying a gas in an exhaust gas system comprising an exhaust duct comprising a filter for filtering fine particles, said method comprising spraying of water mist into said exhaust duct upstream of said filter for purifying said gas, said spraying being effected by at least one spray nozzle causing a negative pressure for sucking the gas into the sprayed spray and by guiding said mixture aside from said filter and guiding thus purified gas into the filter. Due to the method gases can be continuously purified without the filter of the exhaust gas system being clogged. When applied to a room having a fire the method simultaneously enables purification of flue gases, sucking of heat out from the room and enables small particles to be captured by the filter. The present invention also relates to an exhaust gas system.

Abstract: Method of removal of a steam-gas mixture of at least one non-condensable gas and steam from a pressure system technology (1) where the said steam-gas mixture accumulates in at least two places (la) from which the steam-gas mixture is removed and routed through interconnecting pipes (3) to a collecting pipe (4) through which it is let out for further processing, while in all the accumulation places (la) a pressure loss is created between the accumulation place (la) and the collecting pipe(4), being at least 10 times higher than that in the interconnecting pipe (3) with the highest pressure loss, and, at the same time, the required proportion of steam-gas mixture removal, the total required quantity of the steam-gas mixture removed from the technology (1) and the required pressure drop are set for the individual accumulation places (la). The equipment for removal of a steam-gas mixture of at least one non-condensable gas and steam from the pressure system technology (1) containing at least two accumulation places (la) where the steam-gas mixture accumulates has each accumulation place (la) connected via interconnecting pipe (3) with a throttling measurement orifice place (2) with the collecting pipe (4), through which the steam-gas mixture is removed from the accumulation place (la) over a pressure energy reducer (6).

Abstract: Die Erfindung betrifft eine kerntechnische Anlage, insbesondere Kernkraftwerk (4), mit einem Containment (8) und mit einem Ventingsystem (2) zur gefilterten Druckentlastung des Containments (8), wobei • das Ventingsystem (2) eine aus dem Containment (8) in die Umgebung geführte Ventleitung (28) aufweist, in die ein Nasswäscher (12) für den sich beim Venting einstellenden Ventstrom (10) geschaltet ist, • der Nasswäscher (12) einen bereits während des Bereitschaftszustandes vor dem Venting mit einer Waschflüssigkeit (18) gefüllten Pool (26) aufweist, über dem sich ein Gasraum (48) befindet, • die Ventleitung (28) eine in den Nasswäscher (12) geführte Eintrittsleitung (14) für den Ventstrom (10) umfasst, die sich in einem Verteiler (34) in eine Anzahl von Austrittsdüsen (38) verzweigt, • die Austrittdüsen (38) zumindest teilweise in die Waschflüssigkeit (18) im Pool (26) eintauchen. Aufgabe der Erfindung ist es, solch ein Ventingsystem (2) derart weiterzuentwickeln, dass bei gering gehaltenem apparativen und verfahrenstechnischen Aufwand kritische Konzentrationen zündfähiger Gasgemische in allen Betriebszuständen noch zuverlässiger als bislang vermieden sind. Dies wird erfindungsgemäß dadurch erreicht, dass zumindest eine separate Austrittsöffnung (56) vorhanden ist, die über eine Zweigleitung (54, 90) an die Eintrittsleitung (14) oder an den Verteiler (34) angeschlossen ist, und die zumindest während des Bereitschaftszustandes thermisch von der Waschflüssigkeit (18) im Pool (26) isoliert ist.

Abstract: A nuclear power plant (4) comprises a Containment (8) and a filtered Containment venting System (2), • the filtered Containment venting System (2) comprising a pressure relief line (10) leading from inside the Containment (8) to the outside, • a catalytic recombiner (20) for hydrogen removal being located at or shortly after the inlet (12) of the pressure relief line (10) and, further downstream, a wet scrubber (48) being switched into the pressure relief line (10), • the wet scrubber (48) being located inside the Containment (8) and comprising a washing liquid compartment (50) for a washing liquid (54) in it and a gas dome (52) above it, such that during venting Operation a venting stream is washed by the washing liquid (54) and then enters the gas dome (52), • the gas dome (52) being hermetically sealed against the Containment atmosphere (110). It is an objective of the present invention to provide a filtered Containment venting System (2) of the above mentioned type which avoids the risk of the wet scrubber (4) running dry during venting Operation. Therefore, according to the invention the washing liquid compartment (50) is part of a larger reservoir (68) located inside the Containment (8), wherein the washing liquid compartment (50) is in flow communication with the rest of the reservoir (68) such that washing liquid (54) lost in the washing liquid compartment (50) due to evaporation is automatically replenished by a liquid (70) in the reservoir (68).
