A device for passively inerting the gas mixture forming in the reactor containment of a nuclear power plant in an accident situation is proposed, which device is based on the use of chemical substances which react or disintegrate, releasing an inerting gas or gas mixture when a certain temperature of reaction is reached. This device is especially suitable for use in connection with catalytic recombiners for removing hydrogen through oxidation with the oxygen present. The heat resulting from this exothermic process of recombination can be put to use for heating up chemical substances to the required temperature, these having temperatures of reaction that lie above the temperature (approximately 100.degree. C.) that develops in the reactor containment in an accident situation.
A device for preventing the formation of a flammable mixture of hydrogen and oxygen in a reactor containment of a nuclear power plant, said device comprising one or more inerting elements situated in the reactor containment, each element comprising one or more chemical substances which deliver an inerting gas and/or inerting gas mixture through disintegration and/or chemical reaction at temperatures greater than or equal to a respective temperature of reaction.
A device for reducing the risk of deflagration or detonation of a flammable gas in a reactor containment of a nuclear power plant, said device comprising one or more inerting elements situated in the containment, each element comprising one or more chemical substances which deliver an inerting gas and/or inerting gas mixture through disintegration and/or chemical reaction at temperatures greater than or equal to a respective temperature of reaction.
