Radioactive wastes are formed during the production of uranium-plutonium nuclear fuel at enterprises. In the present article the concentration ranges for uranium, plutonium, and neptunium in liquid and cemented wastes corresponding to different radioactivity classes are determined. The concentration ranges are determined for wastes formed in the production of nitride fuel for the initial load, as well as for waste formed on use of recycled uranium, plutonium, and neptunium in production. The effect of 241Am accumulation on the classification of radwaste is determined. The estimated cost of transferring the wastes formed on fabrication of mixed nitride fuel to the national operator for disposal is presented. The technological methods of reducing the cost of waste disposal, including the possibility of forming class-3 wastes for which surface disposal is admissible, are presented. The maximum concentration of plutonium and americium in liquid wastes at which the solidified forms of wastes correspond to class-3 is determined.

铀钚核燃料生产中的放射性废物特性

放射性废物是在企业生产铀钚核燃料过程中形成的。在本文中，确定了对应于不同放射性类别的液体和胶结废物中铀、钚和镎的浓度范围。浓度范围是针对初始负荷的氮化物燃料生产中形成的废物以及在生产中使用回收铀、钚和镎形成的废物确定的。确定了 241Am 积累对放射性废物分类的影响。介绍了将混合氮化物燃料制造过程中形成的废物转移到国家运营商进行处置的估计成本。降低废物处理成本的技术方法，包括形成可接受表面处置的第 3 类废物的可能性。确定液体废物中钚和镅的最大浓度，在该浓度下废物的固化形式对应于第 3 类。
