摘要： A method of removing a radioactive material from a gas includes directing the gas through a bed of salt (112), wherein the gas includes water vapor and the radioactive material. The salt (112) constitutes more than 50 percent by weight of the bed. The method additionally includes condensing the water vapor in the bed and dissolving a portion of the salt (112) to form a salt solution. The method further includes absorbing the radioactive material into the salt solution while a remainder of the gas passes through the bed. A salt filtration system (100) configured to perform the method may be implemented as a pre-filter to an existing filter unit or as a standalone filter.

摘要： [Problem] There is provided an adhesion restraint method of a radionuclide to a carbon steel material of an atomic energy plant, in which an adhesion restraint effect of the radionuclide to the carbon steel material can continue for a longer term.
[Solution] A film forming apparatus is connected to a carbon steel purification system pipe of a BWR plant (S1). A nickel formate aqueous solution and hydrazine are injected into a circulation pipe of the film forming apparatus (S4, S5). An aqueous solution including nickel formate and hydrazine is guided into a purification system pipe subjected to chemical decontamination, and a nickel metal film (80) is formed on an inner surface of the pipe. A platinum ion aqueous solution and hydrazine are injected into the circulation pipe (S9, S10), and an aqueous solution including a platinum ion and hydrazine is supplied to the purification system pipe so as to adhere platinum to the surface of a nickel metal film (80). The film forming apparatus is detached from the purification system pipe, and the BWR plant is started. Reactor water of 200°C or higher is guided into the purification system pipe, and thus the nickel metal film is converted into a nickel ferrite film (82) which is not melted even by the adhering platinum and is stable.摘要翻译： 本发明提供放射性核素对原子能设备的碳钢材料的附着抑制方法，其中放射性核素对碳钢材料的附着抑制效果可以持续较长时间。 [解决方案]将成膜装置连接到BWR设备（S1）的碳钢净化系统管道。 将甲酸镍水溶液和肼注入成膜装置的循环管中（S4，S5）。 将包含甲酸镍和肼的水溶液引导到经过化学净化的净化系统管中，并且在管的内表面上形成镍金属膜（80）。 向循环管内注入铂离子水溶液和肼（S9，S10），将含有铂离子和肼的水溶液供给到净化系统配管，使铂附着在镍金属膜的表面 80）。 将成膜装置从净化系统配管取下，启动BWR设备。 将200℃以上的反应水引导到净化系统管中，由此镍金属膜转变成镍铁氧体膜（82），即使通过附着的铂也不会熔化并且是稳定的。
