我国乏燃料后处理经济性研究

Research on the Economy of Irradiated Fuel Reprocessing in China

随着我国核能产业快速发展,天然铀需求和所产生乏燃料的数量也逐年增加,后处理产业的经济性必然会再次成为发展闭式核燃料循环产业需要解决的问题之一。该文参考经合组织核能署相关研究,开展乏燃料后处理经济性分析,对“一次通过”和后处理两种核燃料循环方式的成本进行测算。结果显示,现阶段后处理方案比“一次通过”更加经济,并且随着天然铀价格的持续上涨与后处理、MOX燃料制造技术成熟所带来的价格下降,其经济性将在未来愈发凸显。

With the rapid development of China's nuclear energy industry,the demand for natural uranium and the amount of produced spent fuel are also increasing year by year,and the economy of the reprocessing industry will inevitably become one of the questions that need to be answered in the development of the closed nuclear fuel cycle industry again.This study refers to relevant research from the OECD Nuclear Energy Agency,analyzes the economy of spent fuel reprocessing,and calculates the costs of two nuclear fuel cycle methods of"once-through"and reprocessing.The results show that the reprocessing scheme is more economical than"once-through"at this stage,and its economy will become increasingly prominent in the future with the continuous rise of the price of natural uranium and the decrease of the price caused by the maturity of reprocessing and MOX fuel manufacturing technology.
