Temperature controller of hydrogen detector in cover gas
专利汇可以提供Temperature controller of hydrogen detector in cover gas专利检索，专利查询，专利分析的服务。并且PURPOSE: To improve the reliability in the water leak detection of a fast neutron reactor by controlling the temperature of a metal thin film portion with the use of a liquid metal which effects substantially the same density to the atomic density of the hydrogen per unit volume in cover gas phase.
CONSTITUTION: A detector 8 is lined with a metal thin film such as an Ni thin film 14 and further with a container 30 of the Ni film, and a metal 31 which is in a liquid state at a temperature in the vicinity of 500°C, and a heater 20 are interposed between the thin film 14 and a guard 15. The thin film 14 and the container 30 are heated by the liquid metal 31 which is heated by the heater 20 and the temperature of the metal 31 is detected by a thermocouple 22. The metal such as Li, which has a low boiling point and an excellent thermal conductivity and which has substantially the same atomic number as hydrogen for the same volume of the metal in the cover gas phase, is used as the metal to be inserted. As a result, even if there is a high heat source so that the flow rate of Ar gases are fluctuated, no large temperature change of the Ni film takes place. As a result the temperature control of the Ni film can be facilitated so that no error signal is generated for the water leak.
