摘要： The invention provides a method for the encapsulation of uranium metal which comprises treating the metal with an encapsulant which comprises a cementitious material and curing the cementitious material, the process additionally comprising the provision of means for the minimisation of the corrosion of the metal. Suitable modes for the provision of means for the minimisation of corrosion include the provision of a source of oxygen within the cement matrix, either by facilitating enhanced oxygen access from the atmosphere using air entraining agents or cenospheres or by the inclusion of an independent source of oxygen, for example a peroxide. An alternative mode for the provision of means for the minimisation of corrosion comprises facilitating the minimisation of the water content of the matrix, which is conveniently achieved by the addition of superplasticisers. The method allows for the long team storage of uranium metal and provides significant benefits in terms of health, safety and the environment.
摘要翻译：本发明提供了一种用于包封铀金属的方法，其包括用包含水泥质材料和固化水泥材料的密封剂处理金属，该方法还包括提供用于最小化金属腐蚀的装置。提供用于最小化腐蚀的手段的合适方式包括：在水泥基体内提供氧源，方法是利用加气剂或空心微球从气氛中增强氧气的通入，或者通过加入独立的氧气源，例如过氧化物。提供用于最小化腐蚀的装置的替代方式包括促进基质的含水量的最小化，这通过添加超增塑剂而方便地实现。该方法允许长期存储铀金属，并在健康，安全和环境方面提供显着的益处。

IPC分类号： G21F9/30
摘要： The invention provides a method for the encapsulation of fine particulate materials which comprises treating these materials with a microfine hydraulic inorganic filler which, typically, comprises a cementitious material, such as Portland Cement. The filler is ground to a much smaller particle size than is normally used in the production of a grout and is provided in the form of an aqueous composition for the treatment of the fine particulate materials by pumping under pressure through these materials such that they become intimately encapsulated. The method is particularly applicable to the treatment of waste materials and, most particularly, waste materials which are encountered in the nuclear industry.
