摘要
由于我国核电工业的发展对金属锆、铪的需求将大幅增加,根据国家规划,至2020年我国将再建30座核电站,届时核电装机容量将由目前的57×105kW增到约34×106kW。核级海绵锆、海绵铪的用量将达到103t。以国内公司的生产运行指标为例,比较了碱熔法、碳化氯化法和沸腾氯化法3种制备氯锆方法的技术经济指标。比较结果表明,3种方法中沸腾氯化法成本最低,其单耗成本依次为沸腾氯化法为8345元,碱熔法为9117元,碳化氯化法为12505元。
With the development of nuclear power industry, the demands of zirconium metal and hafnium metal will increase by a big margin. According to national plan, 30 nuclear power stations will be built by 2020, nuclear power installed capacity will increase from present 57×10^3 kW to 34×10^6 kW by then, and the consumption capacity of zirconium metal and hafnium metal will be 10^3 t. It has been made a comparison of technical and economical index between chlorination, carbonation and fluidization chlorination process preparing zirconium oxychloride for national company in order to provide a basis of construction of large-scale enterprises for zirconium sponge and hafnium sponge. The results show that among the above-mentioned three processes, the production cost by fluidization chlorination is the lowest, the cost in order is： RMB 8 345 by fluidization chlorination, RMB 9 117 by basic process chlorination, RMB 12 505 by carbination process.
