摘要： The present invention provides a chimney for a natural-circulation boiling water reactor having structural soundness capable of standing a horizontal load generated by a flow-induced vibration, an earthquake and the like. The chimney for a natural-circulation boiling water reactor according to the present invention is characterized in that: the chimney is disposed in the inside of a reactor pressure vessel, and includes plural flow channels which guide a steam-water two-phase flow generated in a reactor core to the upper part of the reactor pressure vessel; each of the flow channels is formed partitioned by plural flow channel separation walls whose lower-most part is supported by a chimney lattice plate; and chimney spacers that support the horizontal load each other are arranged between the flow channel separation walls of the adjacent flow channels, and ring-like members that support the horizontal load are arranged at the outermost periphery of the plural flow channels that are supported by the chimney lattice plate.

摘要： A circulation pipe 29 of a chemical decontamination apparatus 28 including a malonic acid injection apparatus 32 and an oxalic acid injection apparatus 37 is connected to a purification system pipe 21, which is made of carbon steel, of a boiling water nuclear power plant. A malonic acid aqueous solution is injected from the malonic acid injection apparatus 32 into the circulation pipe 29. An oxalic acid aqueous solution is injected from the oxalic acid injection apparatus 37 into the circulation pipe 29. A reduction decontaminating solution including a malonic acid of 5200 ppm and an oxalic acid within a range of 50 to 400 ppm is supplied into the purification system pipe 21 through the circulation pipe 29. Reduction decontamination for an inner surface of the purification system pipe 21 is executed. After the reduction decontamination for the purification system pipe 21 finishes, the malonic acid and oxalic acid included in the solution are decomposed and furthermore, the solution is purified.

摘要： A gas supply apparatus of the present invention includes: an operating valve that is placed in the middle of a piping for letting at least gas in a plant flow and that operates a valve main body by the gas flowing in the piping; a first electromagnetic valve 2A that is placed in the middle of the piping and that opens or closes a flow of the gas to the operating valve; and a gas supply source that supplies the first electromagnetic valve 2A with the gas. A gas discharge line of the first electromagnetic valve has a switching valve 3 placed therein and has a second electromagnetic valve 2C placed between the switching valve 3 and the gas supply source. The switching valve 3 switches between a gas discharge from the first electromagnetic valve 2A and a gas supply to the first electromagnetic valve 2A. When a power source is lost, the switching valve 3 is switched to connection to the gas supply source so as to supply the first electromagnetic valve 2A with the gas. At the time of a normal operation, the second electromagnetic valve 2C opens a gas discharge line side and closes a switching valve side, and when the power source is lost, the second electromagnetic valve 2C opens the switching valve side and closes the gas discharge line side. In this way, even when the power source is lost, an operating valve such as an air-operated valve can not only be operated remotely but also be operated safely by a remote operator.

摘要： At the time of loss of coolant accident, when station blackout occurs, hydrogen, radioactive nuclides, and steam are discharged from a broken portion of a pipe connected to a reactor pressure vessel into the primary containment vessel (13). A passive autocatalytic hydrogen treatment apparatus installs a catalytic layer (22) and heat exchanger tubes of a heat exchanger in a casing. High-temperature steam including hydrogen and radioactive nuclides is supplied into the heat exchanger tubes (5) and heats gas supplied into the casing (3). The steam is condensed in the heat exchanger tubes and generates mists. The mists are removed by a mist separator together with the radioactive nuclides. The gas including hydrogen fed from the mist separator (6) in the casing is heated by the aforementioned steam and is introduced into the catalytic layer. Hydrogen is combined with oxygen in the catalytic layer to steam.
