乏燃料后处理工程关键技术元素识别方法研究

Research on Identification Method of Critical Technology Elements of Spent Fuel Reprocessing Project

技术成熟度评价方法是加强技术风险管理,提高乏燃料后处理设施安全可靠性和技术经济性的重要工具。目前,我国乏燃料后处理领域技术成熟度评价体系还是空白,研究团队针对这一问题开展调研、分析和研究工作。关键技术元素识别作为技术成熟度评价体系的重要组成部分是其研究的重点内容。研究中,通过数学建模、矩阵运算和一致性检验方法提出了关键技术元素识别指标体系及判定方法。选取了乏燃料连续溶解器和硝酸铀酰浓缩蒸发器两个代表性技术元素进行了方法检验,结果表明方法可行,结果可靠。

Technology readiness evaluation method is an important tool to strengthen technology risk management and improve the safety, reliability and technical economy of spent fuel reprocessing facilities. At present,the evaluation system in the field of spent fuel reprocessing is still blank, and the research team is carrying out investigation, analysis and research on this blank. As an important part of the technology readiness evaluation system, the identification of critical technology elements is the key content of the technology readiness evaluation system. In the research, through the methods of mathematical modeling, matrix operation and consistency test, the identification index and judgment method of critical technical elements are put forward. Two representative technical elements of spent fuel continuous dissolver and uranyl nitrate enrichment evaporator are selected for method test. The results show that the method is feasible and the results are reliable.
