    摘要： An entrainment-reducing assembly may include a container configured to hold a liquid. A venting arrangement may extend into an upper portion of the container and be configured to direct condensable and non-condensable gases into the container. A suction structure may extend into a lower portion of the container and be configured to carry out an extraction of excess liquid from the container caused by condensed gases. A deflector may be disposed between the suction structure and the venting arrangement within the container. As a result, an entrainment of uncondensed gases during the extraction of the liquid by the suction structure may be reduced or prevented, thereby protecting the pump from cavitation and failure.

    摘要： A passive shutdown system (100) for a liquid metal cooled reactor may include a tube (104) and a neutron absorber (106) within the tube. The tube may be configured to extend through a core of the liquid metal cooled reactor. The tube has an upper end (110) and a lower end (112). The tube defines a flow path for a liquid metal coolant (102). The neutron absorber is a mobile structure configured to partially obstruct a flow of the liquid metal coolant within the flow path. A method of operating a liquid metal cooled reactor may involve the use of the passive shutdown system.

    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： A wet filter for a nuclear reactor primary containment vent that employs an inclined manifold having a plurality of outlets that communicate through a first set of metal fiber filters submerged in a pool of water enclosed within a pressure vessel. A demister suspended above the pool of water to remove any entrained moisture in the filtered effluent before being passed through a second stage of higher density, dry, metal fiber filters connected to a second manifold that communicates with an outlet on the pressure vessel that is connected to an exhaust passage to the atmosphere.
