〔発明の実施例〕
以下、本発明の一実施例のフローシートを第１図に示す
。The present invention enables similar recombination devices to be used within nuclear power generation facilities, whereas combustible gas control system recombination devices are used only in the event of an accident, require periodic performance tests, and take time to start up. The focus is on the exhaust gas treatment equipment recombination device that performs the treatment. Since the exhaust gas treatment equipment recombination device is always used during normal operation, the recombination reaction is constantly monitored and performance maintenance can be confirmed, and the treatment failure is sufficiently large compared to the combustible gas control system. 2 [Embodiment of the Invention] A flow sheet of an embodiment of the present invention is shown in FIG. 1 below.

衰し、排気筒１４を経て大気に放出される。During normal operation, the exhaust gas treatment equipment extracts oxygen, hydrogen, and air from the main condenser 6 using the air extractor 7, dilutes the hydrogen with the driving steam of the air extractor, and recombines the exhaust gas through the exhaust gas preheater 10. Oxygen and hydrogen are introduced into a vessel 11, where the oxygen and hydrogen are recombined to become water vapor, and the water vapor is cooled and condensed in an exhaust gas condenser 12 to become condensed water. After confirming that the gas exiting the exhaust gas condenser 12 has a low hydrogen concentration using a hydrogen concentration measuring device and that there is no risk of hydrogen combustion or explosion, the activated carbon adsorption tower 13 removes the radioactivity of radioactive rare gases such as Kr and Xe. The concentration is attenuated and released into the atmosphere through the exhaust stack 14.

て排気筒より大気に放出される。In the event of a reactor coolant loss accident, the air extractor outlet valve 8 is closed and the valves 3 and 5 are opened. By driving the blower 4, gas within the reactor containment vessel is guided to the exhaust gas treatment facility. The gas led to the exhaust gas treatment equipment is heated to about 130°C to about 150'C in the exhaust gas preheater 10, and then
Oxygen and hydrogen are recombined in the exhaust gas recombiner 11. The gas from which water vapor has been removed in the exhaust gas condenser passes through an activated carbon adsorption tower and is released into the atmosphere from the exhaust stack.

能維持が確保できる。According to this embodiment, a combustible gas control system recombination device for processing oxygen and hydrogen when reactor coolant is lost becomes unnecessary. or,
Since the performance of the exhaust gas treatment equipment recombination device is always checked under normal conditions, performance can be maintained even in the unlikely event of an emergency.

動時間を短縮することができる。Furthermore, since the exhaust gas treatment equipment recombiner remains in operation until the reactor coolant is lost, the exhaust gas preheater 10 and the exhaust gas recombiner 11 are in a high temperature state, and the blower 4 is activated immediately in the event of an accident. Since the recombination reaction can be completed even when the temperature is low, the start-up time can be shortened.

Valve 16 is closed. Also, since the main steam stops, the driving steam for the air extractor 7 is switched from the main steam to the station steam.
