摘要： A method of restraining a diffusion of tritium and an apparatus for same are disclosed. The method includes the step of disposing a hydrogen-absorbing metal in a tritium passage in a direction of diffusion of tritium so that the hydrogen-absorbing metal absorbs tritium to be diffused. The apparatus includes a hydrogen-absorbing metal surrounding a device of a fast breeder reactor. The tritium to be diffused can be readily captured. An arrangement of capturing the tritium permeating the device is simplified in the present invention.

摘要： Of the components making up the pump, one part including the bearing is removably assembled into the other part so that the bearing is received in the other part. This structure allows easy removal of the first part of the pump components from the second part for disassembly and for maintenance and inspection of the pump. The pump can also be reassembled with ease by inserting the first part into the other part.

摘要： This invention relates to a cold trap for collecting impurities from liquid, which comprises a mesh screen and a spacer mesh having higher strength and wider mesh holes than that of the mesh screen interposed between the windings of the mesh screen. According to the present invention, since the spacer mesh supports the mesh screen over the whole surface thereof so that the mesh screen is protected free from break or deformation, the stiffness and collecting efficiency of the mesh section can be maintained prolongedly.
摘要翻译：本发明涉及一种用于从液体中收集杂质的冷阱，其包括网筛和间隔网，隔离网具有比插入在筛网的绕组之间的筛网更高的强度和更宽的网孔。根据本发明，由于间隔网在其整个表面上支撑网状筛网，因此可以保护网眼免受断裂或变形，可以延长网状部分的刚度和收集效率。

摘要： An electrically conductive metal is arranged within a passage for sodium having leaked, and the temperature change of the electrically conductive metal attributed to the heat of vaporization of which the sodium mist deprives the electrically conductive metal upon contact with the latter and subsequent vaporization is detected. The temperature change of the electrically conductive metal is detected in the form of a change in the current or voltage conducting property, and current corresponding to the temperature change is fed back to the electrically conductive metal. The change of the conducting property is taken out as a pulse signal, and a value proportional to the weight of a sodium mist particle is detected from the magnitude of the signal. Further, a value proportional to the weight of the whole mist is detected by the pulse height analysis. The leakage of the sodium is decided by comparing the value of the weight of the whole mist with a predetermined value. The sodium leakage may well be decided by comparing the number of the pulse signals with another predetermined value.
摘要翻译：导电金属被布置在用于泄漏的钠的通道内，并且检测归因于在与之接触时钠雾除去导电金属并随后蒸发的蒸发热的导电金属的温度变化。导电金属的温度变化以电流或导电性能的变化的形式被检测，对应于温度变化的电流被反馈到导电金属。将导电性的变化作为脉冲信号取出，根据信号的大小检测与钠雾粒子的重量成正比的值。此外，通过脉冲高度分析检测与整个雾的重量成比例的值。通过将整个雾的重量的值与预定值进行比较来确定钠的泄漏。可以通过将脉冲信号的数量与另一预定值进行比较来确定钠泄漏。
