    摘要: Cesium can be selectively recovered from a nuclear waste solution containing cesium together with other metal ions by contact with a modified phlogopite which is a hydrated, sodium phlogopite mica. Once the cesium has entered the modified phlogopite it is fixed and can be safely stored for long periods of time.

    摘要: Radioactive waste material, such as that resulting from radioactive weapons plant operation or from nuclear fuel reprocessing, in suitable form, such as radionuclide-containing oxide and/or oxyhydroxide and/or hydroxide particles, is held by a metal or metal "alloy" to an electrically conductive cathodic material upon which the metal or alloy is electrodeposited. In this way the radionuclide species including strontium and/or cesium, which are biologically extremely hazardous, are incorporated into a metal matrix held to a base and may be disposed of, as by underground storage, in such form, which is considered to be more resistant to dissolution by ground water and to damage by mechanical stresses arising from tectonic activity than are glasses or ceramics incorporating radionuclides. In improvements of the process and of the resulting radionuclide-including article, the article is electrolytically or otherwise covered or coated with suitably corrosion resistant and mechanical damage resistant covering(s) or coating(s), as by continuing electrodeposition of the metal, sometimes after addition of more material, which is a source of the metal, to a suitable electrolyte, or after replacement of the electrolyte.

    摘要: Embodiments include a process including providing a microwave radiation source and a processing chamber. The process includes generating a region of pure magnetic field from the microwave radiation in the processing chamber. A region of pure electric field from the microwave radiation is also generated. A material is positioned in the region of pure magnetic field while no portion of the material is positioned in the region of pure electric field, and the material is heated in the region of pure magnetic field. The heating may be conducted to sinter the material. The material may includes a metal.
