Abstract: The present disclosure relates to a reactor pressure-relieving filter system having an interior space hermetically enclosed by a pressure-resistant reactor casing, at least one pressure-relieving opening through the reactor casing, and a dry filter for a gas mass flow emerging from the pressure-relieving opening when there is excess pressure in the interior space. The filtering efficiency can depend both on the average dwell time of the gas mass flow in the dry filter and on the temperature difference between the gas mass flow and the respective dew point. A flow channel connects the pressure-relieving opening and the dry filter. A passive orifice plate is provided upstream of the dry filter in the flow channel.

Abstract: A fuel element storage and cooling configuration includes a fuel element storage pool and a cooling system having at least one first heat exchanger disposed in the fuel element storage pool and at least one second heat exchanger disposed in a heat sink and located at a distance therefrom, above a highest point of the first heat exchanger. The two heat exchangers are connected, using a pipe system, to form a closed circuit, which is at least partially filled with a flowable coolant. If the temperature of the first heat exchanger is increased with respect to the second heat exchanger, natural circulation of the coolant, and thus heat transport from the fuel element storage pool to the heat sink, is ensured without a pump apparatus.
