摘要： Die Erfindung betrifft ein Reaktordruckentlastungsfiltersystem (10) mit einem Druckbehälter (12) in dem ein Filterbett angeordnet ist, das eine erste Filterbettschicht (24) aufweisend ein erstes Filtermaterial zur Rückhaltung von Aerosolen hat. Der Druckbehälter (12) weist geodätisch oberhalb des Filterbettes wenigstens eine Einlassöffnung (18) auf, durch die ein zu filterndes Medium in den Druckbehälter (12) zugeführt ist. Das Filterbett ist dabei von einem geodätisch unten angeordneten Druckbehälterboden durch ein Tragsystem beabstandet, wobei eine Druckbehälterwand im Druckbehälterboden und/oder in einem Druckbehälterwandbereich zwischen dem Druckbehälterboden und dem Filterbett wenigstens eine Auslassöffnung (38) aufweist, durch die das gefilterte Medium nach dem Durchströmen des Filterbettes aus dem Druckbehälter (12) ausgeleitet ist. Das Filterbett weist zudem eine zweite horizontal angeordnete Filterbettschicht (28) mit einem zweiten Filtermaterial zur Abscheidung von gasförmigen radioaktiven Stoffen auf und die zweite Filterbettschicht (28) ist in geodätischer Richtung oberhalb des Tragsystems angeordnet.

摘要： A system (100) and a method for capturing gaseous, particulate and liquid radioactive material released from primary containment (3) of a Light Water Reactor (LWR) during severe accident conditions. The system includes a below-grade media area (4), connected to a reactor pressure vessel (RPV) and portions of primary containment (3), providing varying levels of adsorption / absorption of the radioactive material. The media area (4) is located on-site to offer a passive, self-regulating structure for stabilizing a nuclear reactor. The capture system provides for liquid drainage and gaseous venting of the radioactive material, and a treatment capable of treating the media following stabilization of the reactor.

摘要： To provide a cooling system of a reactor suppression pool capable of cooling suppression pool water and improving the safety of a reactor in the case where an event surpassing a postulated initiating event occurs, or in the case where cooling of the suppression pool water by a residual heat removable system does not function. A cooling system of a reactor suppression pool according to the present invention includes a heat exchanger for cooling suppression pool water installed in the middle of a suppression pool water cooling line, operating when the temperature of the suppression pool water reaches a given temperature, performing heat exchange with the suppression pool water from a suppression pool water cleanup system suction line to cool the water, and returning the cooled suppression pool water to the suppression pool through a suppression pool water cleanup system discharge line.

摘要： A dry FCVS for a nuclear reactor containment is provided. The dry FCVS includes a housing and a round and/or elongated aerosol filter inside the housing for removing contaminant aerosols from gas passing through the housing during venting of the containment. The housing includes at least one inlet portion configured for directing gas into the aerosol filter during the venting of the containment and an outlet portion for gas filtered by the aerosol filter during the venting of the containment. The dry filtered containment venting system is arranged and configured such that when a flow of gas through the outlet portion is closed off at least one of convective, radiant and conductive heat transfer removes decay heat of aerosols captured in the aerosol filter.
