摘要： PROBLEM TO BE SOLVED: To remove hydrogen gas plentifully generated in a reactor container efficiently and in long term without leaking out the gas in the container. SOLUTION: A reactor container 1 containing a reactor pressure vessel 5 is equipped with a flammable gas processor 9 which is characterized by using a catalyst 10 promoting recombining of hydrogen gas and oxygen gas and is provided with an electrical heater 11 and an electrode adsorbing hydrogen gas and an electrode adsorbing oxygen gas as power source operating the heater 11, connected with fuel battery 15 converting the recombining energy of hydrogen and oxygen to electric energy, elevating part of or whole temperature of the catalyst 10, improving ignition of the catalyst 10 and reduce the hydrogen gas concentration inside the reactor container 1.

摘要： PROBLEM TO BE SOLVED: To effectively diminish pressure rise in a reactor container caused by a large quantity of hydrogen gas at the time of a severe accident by extracting hydrogen gas generated inside the reactor container to the outside by a hydrogen separator using hydrogen separation membrane. SOLUTION: A hydrogen separator 4 is constituted by bundling hydrogen separation membranes 5 of a cylindrical pipe and connecting the upper parts or both end parts. Hydrogen gas filled in a reactor container 1 permeates the inside from the outside of the hydrogen separation membranes 5 to be collected inside the hydrogen separator 4. Steam flows into the hydrogen separator 4 through a purge gas suction piping 55 to purge hydrogen gas, and the collected hydrogen gas is led to the outside of the container 1 through hydrogen discharge piping 6. A large quantity of hydrogen gas generated by water-metal reaction between cooling water and a fuel pipe at the time of a severe accident can therefore be treated effectively without venting the container 1 and without emitting a radioactive fission product to the outside.

摘要： PROBLEM TO BE SOLVED: To restrain sea water as a cooling water from flowing into a steam generator and the like because of leakage, by comprising a condensate condensing portion having a tube nest of heat exchanger tube and a condensate stagnation portion for stagnating the condensate condensed in the condensate condensing portion, detecting water quality of the condensate, and controlling a control valve interposed in a water supply system based on the detected values. SOLUTION: Steam exhausted from a steam turbine 51 is flowed into a condenser 6. The steam passes through a tube nest of a heat exchanger tube in which sea water as cooling water is flowed, and thereby the team is cooled. Then the steam is condensed to become condensate, and the condensate is dropped at a hot well portion. A condensate pump 13 pumps up the generated condensate so that the condensate is supplied to a steam generator 60 via a water supply pipe line 6a and a boiler feed pump 15. In this case, a plurality of take-out ports for water to be inspected is provided at the hot well portion, and detecting portions 55, 65 carry out water quality examination of the water extracted from the take-out ports. When leakage of the sea water is detected as a result of the examinations, a control device 64 makes a feed water stop valve 17 close to prevent sea water from flowing into the steam generator and the like.
