摘要： PROBLEM TO BE SOLVED: To reduce cost and improve reliability by removing decay heat with circulation of NaK as liquid metal cooling material using a simple constitution, without using active components as a pump and the like. SOLUTION: With the decay heat removal system, NaK is circulated in a pipe 13 and decay heat generated inside a reactor vessel is continuously removed and the system comprises a heat exchanger 15, an air cooler 16 and a hot-pass switch 20. The heat exchanger 15 exchanges heat between the inside of the reactor vessel 12 and the NaK flowing inside the pipe 13 to cool the inside of the reactor vessel 12 and heat NaK. The air cooler is placed above the heat exchanger 15 and naturally cools the NaK. The hot-pass switch 20 makes NaK be supplied to the air cooler 16 side by way of by-pass pipes 21, 24 and 22 when NaK exceeds a specific temperature, and be supplied to the air cooler 16 side by flowing in the pipes 13 and 23, without moving to the by-pass pipes 21, 24 and 22, when it is below the specific temperature.

摘要： PROBLEM TO BE SOLVED: To make it possible to easily detect the leakage of a substance to be detected at a high speed by using hydrogen in a solid electrolyte as a detector that detects the leakage of water from a heat transfer pipe. SOLUTION: A hydrogen concentration meter composed of a solid electrolyte 7 is used in this water leakage detector. In other words, electrodes 8 are placed on the outer surface of the solid electrolyte 7 immersed in sodium 12 and a lead wire 11 is connected to one of the electrodes 8. Electrodes 9 are also placed on the inner surface of the solid electrolyte 7, and a lead wire 10 is connected to one of the electrodes 9. Then, a hydrogen gas of a known concentration is supplied to the side of the electrodes 9 and the concentration of hydrogen in the sodium 12 is measured by the potential difference between the lead wires 10 and 11 (the voltage of electromotive force generated by the difference in the concentration of hydrogen on the outer and inner surfaces of the solid electrolyte 7) to detect whether water leaks in the sodium 12 or not. In this way, the solid electrolyte 7 is immersed in the sodium 12, only the potential difference between the outer and inner sides is measured and the electromotive force generated in the solid electrolyte 7 is used, whereby the leakage of water is easily detected at a high speed.

A heater 6 heats a fluid to be detected, which flows into from a fluid entrance, and the gap between the support pipe 3 and the protective pipe 4 is formed as the flow passage 7 of the fluid to be detected. The heated fluid to be detected is moved upward along the flow passage 7 and flows out to the outside of the leak detector 1 from a fluid exist 8. In the sensor part 2, a comparison gas is filled into a comparison-gas filing part 9 which is under predetermined pressure. Electromotive force is generated according to the difference between its pressure and the pressure of the same kind of gas obtained in the fluid to be detected, flowing in the flow passage 7. A voltmeter 10 measures the electromotive force, and a termometer 11 measures the temperature of the fluid to be measured, which passes through the inside of the flow passage 7.
