摘　　要：为了比较稍加浓铀(SEU)与天然铀燃料的优劣,寻找最优的稍加浓铀富集度水平,本文利用WIMS-AECL和ORIGEN程序研究不同富集度的CANDU-6堆燃料在燃料循环成本、天然铀消耗量、高放废物积累等方面的表现。结果显示,采用稍加浓铀可节约20%以上的天然铀,乏燃料量减少30%以上,燃料循环成本降低50%以上;1.3%是最优的富集度水平。In order to compare the advantages and disadvantages between natural uranium and slightly enriched uranium, and determine the most optimized slightly enriched uranium level, the fuel cycle cost, natural uranium consuming and high-level waste accumulation are studied for CANDU-6 reactor with various enriched level fuel. The codes used in this study are WIMS-AECL and ORIGEN2. The results show that the slightly enriched uranium can save natural uranium of more than twenty percent, reduce spent fuel accumulation of more than thirty percent and cut down fuel cycle cost of fifty percent. The study indicats that 1.3% is the most optimized enriched level.
