摘要： An apparatus for removing flammable gas is started only when a concentration change in the flammable gas in a primary containment vessel is detected, so that the decrease in activity of a catalyst due to a catalyst poison is prevented. This apparatus has a catalytic recombining apparatus equipped with a catalyst 1 for reacting the flammable gas, a case 2 that houses the catalyst, and lids 4a and 4b installed at openings 3a and 3b of the case 2. Adhesive parts 5a and 5b which adhere the lids 4a and 4b and the case 2 is melted at high temperatures, and heating elements 6a and 6b composed of an oxidizing catalyst of hydrogen is installed in contact with the adhesive parts 5a and 5b. Thus, the lids are not only closed under normal conditions but opened when the adhesive parts 5a and 5b being melted along with the temperature increase in the surrounding atmosphere.

摘要： A core catcher includes a holding surface that catches and holds corium and that introduces a surrounding coolant into the core catcher and cool the core catcher by heat exchange with the introduced coolant. The holding surface and the cooling unit are constructed by arranging blocks which each include a polyhedron having at least one pair of parallel surfaces and having an opening portion formed in a surface located in a lateral direction when a first surface that is one of the parallel surfaces is arranged as a bottom surface and are configured such that the polyhedrons communicate with each other via the opening portion when the polyhedrons are arranged adjacent in the lateral direction. The core catcher can achieve easier installation of the blocks without an increase in installation cost.

The number of the second stage cooling channels is larger than that of the first stage cooling channels. Cooling water is supplied from a cooling water injection opening and distributed to the first cooling water channels at a distributor. An intermediate header is formed between the first and the second cooling water channels, and the cooling water is distributed to the second cooling water channels uniformly.

摘要： A reactor containment vessel cooling technology for preventing the cooling capability and structural integrity of a reactor containment vessel cooling system from decreasing by lowering the temperature of water vapor and gases acquired by the reactor containment vessel cooling system is provided. Based on the technology, the present invention provides a reactor containment vessel cooling system that acquires water vapor in a reactor containment vessel by using water vapor pressure in the vessel as a drive force, condenses the acquired water vapor into condensate, and cools the reactor containment vessel with the condensate. The reactor containment vessel cooling system includes a heat exchange pool 21 that is arranged apart from a dry well 15 and a suppression chamber 16 in the reactor containment vessel 10 and stores a medium for cooling water vapor, a heat exchanger 22 that is immersed in the heat exchange pool 21, acquires water vapor from the dry well 15 in the reactor containment vessel 10, and performs heat exchange between the eater vapor and the cooling medium in the heat exchange pool 21 to generate condensate, and a condensate drain pipe 25 that extracts the condensate from the heat exchanger 22 and guides and discharges the condensate toward a reactor pressure vessel 12.
