摘　　要：在梳理不同国家燃料元件设计安全要求的基础上,本文总结了燃料元件总的安全要求,分析了美国核管会标准审评大纲中对燃料元件及燃料系统设计评价和验收准则的要求,结合其规定的审评原则和方法,重点对Frarnatome Mark-B11组件和西屋16×16 NGF组件工程应用的审评实践进行了研究。国外燃料元件工程应用的审评实践表明:我国自主品牌燃料元件设计的安全评价可基于原有设计的运行经验和安全评价结果,应重点关注设计变更对安全评价的影响;安全分析的验收原则可参考美国核管会的要求和审评实践,结合我国的现行法规标准的要求,形成我国自主品牌燃料组件安全分析的验收准则。The overall safety requirements for nuclear element design are summarized on the basis of investigating regulations and standards used in different countries. The specifications for nuclear elements and systems in standard review plan （SRP） published by Nuclear Regulation Committee （NRC） are reviewed. Besides, the design evaluation methods and acceptance criteria are especially analyzed in detail. The safety review processes of Frarnatome Mark-Bll assembly and Westinghouse 16x16 NGF assembly are then investigated respectively according to principles and methods specified by NRC. The practices of safety review for fuel assembly engineering application from abroad show that design evaluations for nuclear elements that improved or developed by our nation should be based on existing operating experience and original design safety evaluation results. The special attention should be paid to effects result from design changes. In view of current regulations and standards, the acceptance criteria of safety analysis for fuel assembly developed in our nation could be established by taking the requirements and practices of NRC into account.
