Abstract: The invention relates to a nuclear power plant including a containment vessel including a reactor pressure vessel for receiving fissionable nuclear fuel, an aerosol filter stage a pressure relief conduit through which a gas volume flow which is filtered in the aerosol filter stage is releasable to ambient through a pass through opening in the containment vessel, and an iodine filter stage through which the gas volume flow that is filtered in the aerosol filter stage is filterable before being released to the ambient, wherein the iodine filter stage is arranged within the containment vessel, characterized in that the aerosol filter stage and the iodine filter stage are connected with one another so that transferring the gas volume flow from the aerosol filter stage to the iodine filter stage is performed essentially at an identical pressure level.

Abstract: A device for reducing air humidity in a room, the device comprising: a housing including an air inlet cross section and an air outlet cross section; a fan unit configured to take air into the air inlet cross section; a refrigeration unit configured to cool the air below a dew point; a first temperature measuring device configured to measure an air temperature of the air taken into the air inlet cross section; a second temperature measuring device configured to measure an air humidity of the air taken into the air inlet cross section; a third temperature measuring device configured to measure a surface temperature of a room boundary surface of the room; and a control device configured to process measured values from the first temperature measuring device, the second temperature measuring device and the third temperature measuring device to control the device for reducing the air humidity in the room.
