摘要： A containment protection system (2) for treating the atmosphere present in the containment (4) of a nuclear facility (6), particularly a nuclear power plant, in case of critical incidents involving extensive release of hydrogen (H
2 ) and steam is to be able to effectively and quickly relieve such conditions in a largely passive manner and where possible without contaminating the environment. According to the invention, the containment protection system (2) has for this purpose a circuit, which comprises a conduction system (10, 72, 120, 128) and which is provided for connecting to the containment (4), out of the containment (4) and back again for a fluid flow, more particularly having the following components fluidically connected in series: a recombination device (20) for recombining hydrogen (H2) contained in the fluid flow with oxygen (O2) to form steam (H2O); a condensation device (74) connected downstream of the recombination device (20) for condensing steam fractions contained in the fluid flow with means for diverting the condensate (94) out of the fluid flow; drive means (18, 180) for the fluid flow, a heat exchanger (96) being provided for an at least partial re-cooling of the condensation device (74) and being connected on the inlet side via a feed line (144) to a storage tank (140) for liquid nitrogen (N2).

摘要： The invention relates to a pressure release system (18) for a containment structure (4) of a nuclear installation (2), having a pressure release line (16) which is guided through the containment structure (4) and which can be closed off by means of a shut-off fitting (30, 32), wherein a wet scrubber (36) for the pressure release gas flow generated during pressure release operation with the shut-off fitting (30, 32) open is connected into a section of the pressure release line (16) situated outside the containment structure (4). Based on this, it is the intention to permit effective and reliable operation of the wet scrubber (36) with a simultaneously compact design, in particular with regard to the amounts of washing fluid (52) that must be kept available. This is achieved according to the invention by means of • a reservoir (67) which is arranged in the containment structure (4) or connected in terms of flow thereto such that a positive pressure prevailing in the containment structure (4) in relation to the outside environment is at least partially, preferably predominantly or entirely, transmitted to the reservoir (67), and • a feed line (68), which leads from the reservoir (67) to the wet scrubber (36) and which can be closed off by means of a shut-off fitting (72), for the feed of liquid (14), which acts as washing fluid (52), from the reservoir (67) to the wet scrubber (36).

摘要： The invention addresses the problem of reinforcing a nuclear plant (2), comprising a containment shell (4) and at least one pressure relief line (10) which is lead out from the containment shell (4) and which can be shut by means of a shut-off valve (14) and through which a pressure relief flow can flow in relief mode when the shut-off valve (14) is open, such that the nuclear plant is designed to cope in a particularly reliable manner with critical scenarios in which a significant increase in pressure occurs inside the containment shell (4) simultaneously with the release of hydrogen (H
2 ) and/or carbon monoxide (CO). To this end, a gas flow treatment device (24) is located inside the containment shell (4) on the inlet side, arranged upstream of the respective pressure relief line (10) and comprises a chimney-like flow channel (26) which is enclosed by a lateral shell surface (28) and which has a lower inflow opening (30) and an upper inflow and outflow opening (32), a first group of catalytic elements (34) being arranged above the lower inflow opening (32) in order to reduce hydrogen (H
2 ) and/or carbon monoxide (CO) in the flow channel (26), and the pressure relief line (10) having an inlet opening (22) which is arranged above the first group of catalytic elements (34) and below the upper inflow and outflow opening (32) in the shell surface (28), such that, in the event of a critical disruption in which hydrogen (H
2 ) and/or carbon monoxide (CO) are released in the containment shell (4), a gas mixture which is present in the containment shell (4) flows through the flow channel (26) from the bottom to the top according to the principle of natural convection in a convection mode which precedes the relief mode and in which the shut-off valve (14) is closed, and, in the relief mode, the gas mixture flows into the flow channel (26) from the bottom and preferably also from the top according to the principle of forced overflow and flows out as a pressure relief flow via the pressure relief line (10).

摘要： The invention relates to a method and corresponding device for depressurizing a nuclear power plant (2) having a containment shell (4) for containing activity carriers and having an outlet (10, 10') for a depressurization flow, wherein the depressurization flow is conducted out of the containment shell (4) into the atmosphere via a depressurization line (12, 12') provided with a filter system, wherein the filter system comprises a filter chamber (16) having a filter chamber inlet (124), a filter chamber outlet (128), and a sorbent filter (18) lying therebetween, and wherein the depressurization flow is first conducted in a high-pressure section (70), then is depressurized by means of expansion at a throttle device (72), then conducted at least partially through the filter chamber (16) having the sorbent filter (18), and finally blown out into the atmosphere. In order to enable an especially efficient and effective retention of activity carriers contained in the depressurization flow, in particular organic compounds containing iodine, the depressurization flow depressurized by the throttle device (72) is conducted through a superheating section (80) immediately before the depressurization flow enters the filter chamber (16), in which superheating section the depressurization flow is heated by direct or indirect heat transfer from the depressurization flow not yet depressurized in the high-pressure section (70) to a temperature that is at least 10 °C, preferably 20 °C to 50 °C, above the dew point temperature present there.
