摘要： A mobile processing system is disclosed for the removal of radioactive contaminants from nuclear process waste water. The system is fully scalable, modular, and portable allowing the system to be fully customizable according the site-specific remediation requirements. It is designed to be both transported and operated from standard sized intermodal containers or custom designed enclosures for increased mobility between sites and on-site, further increasing the speed and ease with which the system may be deployed. Additionally, the system is completely modular wherein the various different modules perform different forms or stages of waste water remediation and may be connected in parallel and/or in series. Depending on the needs of the particular site, one or more different processes may be used. In some embodiments, one or more of the same modules may be used in the same operation.

摘要： Processes, systems, and methods for selectively regenerating an ion exchange resin generally comprises washing the ion exchange resin with an elution agent that encourages only selected contaminants, and especially selected radioactive isotopes, to disengage or decouple from the resin and enter solution in the elution agent, which thereafter is identified as the elution agent solution. The elution agent solution is then passed through a column of isotope-specific media (ISM). When the selected radioactive isotopes within the elution agent solution come into contact with the constituent media isotopes of the ISM, the selected radioactive isotopes are retained on the reactive surface areas of the ISM or within the interstitial spaces of the porous structures of the constituent media isotopes of the ISM. In some embodiments, the constituent media isotopes of the ISM are embedded, impregnated, or coated with the specific radioactive isotope that the particular ISM are adapted to separate.

摘要： Methods are provided for characterizing samples containing chemical elements such as rare earth elements, actinides, and heavy transition metals by treating the samples to form volatile complexes of the elements (e.g., β-diketonate complexes or other organic ligand complexes of the elements) and then analyzing the complexes, for example, via gas-phase thermochromatography. Also provided are methods for separating and/or recovering such chemical elements. The methods produce less waste and can be performed more rapidly than conventional liquid extraction methods and can provide separated elements of high purity (e.g., 99.9999% purity).

摘要： Submersible media filters and submersible columns for use in removing radioactive isotopes and other contaminants from a fluid stream, such as a fluid stream from the primary coolant loop of a nuclear reactor system or a fluid stream from a spent-fuel pool. Generally, these submersible media filters and submersible columns are adapted to be submersed in the fluid stream, and additionally the filters are adapted to be vitrified after use, resulting in a stabilized, non-leaching final waste product with a substantially reduced volume compared to the original filter. In several embodiments, the submersible media filters and submersible columns include isotope-specific media (ISM).

摘要： Nonconjugated conductive polymers absorb radioactive iodine, therefore are useful for protection against nuclear radiation. These polymers have at least one double bond per repeat unit. The ratio of the number of double bonds to the total number of bonds along the polymer chain is less than half. Examples of nonconjugated conductive polymers include: cis-1,4-polyisoprene (natural rubber), trans-1,4-polyisoprene (gutta percha), polybutadiene, polydimethyl butadiene, poly(b-pinene), styrene butadiene rubber (SBR), polyalloocimene, polynorbornene and many others. Through interaction with iodine atoms the double bonds in the nonconjugated polymers transform into radical cations leading to a dark color. The iodine atoms remain (immobile) bound to the polymer chain through the charge-transfer interaction, these polymers are very inexpensive and can be easily processed into any shape, structure and size. Therefore, these are useful for protection against nuclear radiation including radioactive iodine. These polymers when used as a thick cover can provide safe storage of nuclear waste materials including spent fuel rods.

摘要翻译： 非共轭导电聚合物吸收放射性碘，因此可用于防止核辐射。 这些聚合物每个重复单元具有至少一个双键。 双键数与沿聚合物链的总键数的比例小于一半。 非共轭导电聚合物的实例包括：顺式-1,4-聚异戊二烯（天然橡胶），反式-1,4-聚异戊二烯（gutta percha），聚丁二烯，聚二甲基丁二烯，聚（b-蒎烯），丁苯橡胶（SBR） 多烯烃，聚降冰片烯等。 通过与碘原子的相互作用，非共轭聚合物中的双键转化成自由基阳离子，导致暗色。 碘原子通过电荷转移相互作用而保持（固定）与聚合物链结合，这些聚合物非常便宜，并且可以容易地加工成任何形状，结构和尺寸。 因此，这些可用于防止包括放射性碘在内的核辐射。 当用作厚盖时，这些聚合物可以提供包括乏燃料棒在内的核废料的安全储存。

摘要： A radioactive debris trap to be installed in a steam generator for removing debris in the primary flow of a nuclear power plant's primary heat transport system. The debris trap includes an outer cylinder and a coaxial inner cylinder both having a top end and a bottom end. A top plate connects the top ends of the outer and inner cylinders. A bottom plate which encloses the trap is connected to the bottom end of the outer cylinder. There is a gap between the bottom end of the inner cylinder and the bottom plate through which primary flow enters a settling chamber located in an annular gap between the outer and inner cylinders. Several small holes are located at the top end of the outer cylinder through which liquid exits the debris trap. A means for fixedly connecting the debris trap to the steam generator is provided on the outer surface of the outer cylinder. Also included is a means for removing the radioactive debris trap from the steam generator without exposing personnel to excessive radiation.

摘要： Toxic substances such as heavy metals are extracted from a medium using a sorbent composition. The sorbent composition is derived by sulfidation of red mud, which contains hydrated ferric oxides derived from the Bayer processing of bauxite ores. Exemplary sulfidizing compounds are H2S, Na2S, K2S, (NH4)2S, and CaSx. The sulfur content typically is from about 0.2 to about 10% above the residual sulfur in the red mud. Sulfidized red mud is an improved sorbent compared to red mud for most of the heavy metals tested (Hg, Cr, Pb, Cu, Zn, Cd, Se, Th, and U). Unlike red mud, sulfidized red mud does not leach naturally contained metals. Sulfidized red mud also prevents leaching of metals when mixed with red mud. Mixtures of sulfidized red mud and red mud are more effective for sorbing other ions, such as As, Co, Mn, and Sr, than sulfidized red mud alone.

摘要翻译： 使用吸附剂组合物从介质中提取有毒物质如重金属。 吸附剂组合物是通过红泥硫化产生的，该泥浆含有源于铝土矿的拜耳处理的水合氧化铁。 示例性硫化化合物是H 2 S，Na 2 S，K 2 S，（NH 4）2 S和CaS x。 硫含量通常比红泥中的残留硫高约0.2至约10％。 与大部分测试重金属（Hg，Cr，Pb，Cu，Zn，Cd，Se，Th和U）的红泥相比，硫化红泥是一种改进的吸附剂。 与红泥不同，硫化红泥不会浸出天然含有的金属。 硫化红泥还可防止与红泥混合时金属浸出。 硫化红泥和红泥的混合物比单独硫化红泥更有效地吸附其他离子，如As，Co，Mn和Sr。
