在處理放射性污染的廢金屬時，去污技術的選擇至關重要。影響放射性廢金屬去污技術選擇的因素可能有:污染核素、污染水平;放射性污染廢金屬的種類、幾何形狀;國家現行標準(清潔解控水平、放射性廢物分類、個人劑量限值等);廢物管理費用;國家在退役廢物管理方面的經濟承受能力 The selection of decontamination technology is very important when dealing with radioactive waste metal. The factors that affect the selection of radioactive waste metal removal technology may be: pollution nuclide, pollution level, type and geometry of radioactive waste metal; national current standard (clean solution control level, radioactive waste classification, individual dose limit value, etc.); waste management cost; State Economic endurance ability in the management of decommissioned waste. 及不同去污技術的技術經濟比較。 And the technical and economic comparison of the different decontamination technology. 在對現有去污技術進行簡要的技術經濟評估后，根據我國實際情況，合理地組合去污技術就有可能獲得合理的退役廢金屬處理技術路線。 After a brief technical and economic assessment of the existing decontamination technology, it is possible to obtain a reasonable technical route for the disposal of waste metals according to the actual situation in our country. 放射性廢金屬處理技術 Treatment technology of radioactive waste metal 目前，我國已經開發的放射性污染廢金屬去污技術有: 化學法初步、深度去污技術;機械法初步、深度去污技術;熔煉法深度去污技術等。 At present, the technology for decontamination of radioactive waste metal has been developed in China: preliminary chemical method, deep decontamination technology, preliminary mechanical method, deep decontamination technology, and deep decontamination technology of smelting process. 在評價這些去污技術的優缺點時，主要著眼于下列幾個方面:現有去污技術對安全和環境的安全性:去污效率 ;現有技術的成熟程度及相關運行費用;廢金屬資源的可再循環再利用或限制性利用的可能性;全程廢物管理費用;現有技術對各類廢金屬的適應性和有效性; In evaluating the merits and demerits of these decontamination technologies, we mainly focus on the following aspects: the safety and environmental safety of the existing decontamination technology, the efficiency of decontamination, the maturity of the existing technology and the related operating costs; the possibility of recycling or restrictive utilization of the waste metal resources; the cost of the whole process of waste management; and the existing technology. The adaptability and effectiveness of all kinds of waste metals; 從各種待退役的設施中.可能產生的廢金屬類別有:不銹鋼、碳鋼、鎳和鎳基合金、銅及銅基合金、鋁及鋁基合金等。由于各種設施的復雜性和任務上的差別，廢金屬的幾何形狀也千差萬別。 From a variety of facilities to be decommissioned, the possible categories of scrap metal include: stainless steel, carbon steel, nickel and nickel based alloys, copper and copper based alloys, aluminum and aluminum based alloys. Because of the complexity of different facilities and the difference of tasks, the geometry of scrap metal is also different.
