摘要： A sealing apparatus for mitigating emissions of a hazardous gas flowing between first and second regions. A body of the apparatus includes at least one inlet, at least one outlet spaced apart from the at least one inlet, and a channel connecting the at least one inlet and the at least one outlet in fluid communication. Treatment material housed in at least a portion of the channel is adapted to treat the hazardous gas to form a conditioned gas. In use, the hazardous gas being emitted from the first region is received at the at least one inlet, and the conditioned gas is discharged to the second region at the at least one outlet. The apparatus may be used in combination with a storage container housing radioactive or other toxic waste.

摘要： The present invention relates to a passive filtration system for a fuel handling area having a spent fuel pool in a nuclear reactor. The passive filtration system reduces a discharge into the atmosphere of particulates, such as radioactive particulates, generated in a spent fuel pool boiling event. The passive filtration system includes a discharge path, a vent mechanism positioned between the fuel handling area and the discharge path. The vent mechanism is structured to release a steam and air mixture from the fuel handling area to the discharge path. The steam and air mixture includes the particulates. The passive filtration system further includes an air filtration unit located in the discharge path and this unit has at least one passive filter. The steam and air mixture is forced through the at least one passive filter due to a differential pressure generated in the fuel handling area. The at least one passive filter traps particulates from the steam and air mixture to produce a filtered steam and air mixture that is released through a second vent mechanism into the atmosphere.

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： This filter comprises a plurality of reservoirs (1, 2 and 3) connected in series by connecting ducts (4, 5). The flow of gaseous streams therein is subject to multiple obstacles which have the effect of effectively trapping the constituents with the highest molecular weight without substantially impeding the diffusion of the light constituents. This can be achieved through the use of internal baffles (9) or an array (6) of thinner ducts (7), for example at the entry to the filter. Possible application to the separation of hydrogen and radon produced by nuclear waste.

摘要翻译： 该过滤器包括多个通过连接管道（4,5）串联连接的储存器（1,2和3）。 其中的气流的流动受到多重障碍的影响，其有效地捕集具有最高分子量的组分，而基本上不妨碍轻组分的扩散。 这可以通过例如在过滤器入口处使用内部挡板（9）或更薄的管道（7）的阵列（6）来实现。 核废料产生的氢和氡分离的可能应用。
