| 摘 要： | 简要介绍了聚变－裂变混合堆难内燃料循环研究的方法、程序和程序的改进，提出了适用于托卡马克商用混合堆ＴＣＢ设计的３种堆内燃料循环模型，研究了堆内燃料的装卸模式与增殖燃料２３９Ｐｕ生产量的关系，增殖燃料加浓度的选择，提出了抑制裂变直接加浓核燃料概念，并给出了有关的计算结果。结果表明，在ＴＣＢ设计中，采用抑制裂变直接加浓核燃料模式，可实现年产２３９Ｐｕ燃料２２００ｋｇ且加浓度大于３％。结果还表明，采用分区卸料方式，可有效地减小系统的功率摆动和裂变率，这对商用混合堆设计尤其重要。

| Abstract: | In this paper,the method and computer code of the fuel cycle study for hybrid reactors are briefly introduced.Three kinds of fuel management model suitable for the Tokamak CommercialBreeder TCB are presented.The loading and discharge model of fission fuel versus production of239Pu,selection of enrichment degree of 239 Pu,and issues of fission suppression to realize the directenrichment of the nuclear fuel are investigated, and the calculation results are given as well. Theresults show that the239 Pu annual production of 2200kg with 3 % degree of enrichment are possiblein TCB design. The results also show that using the separate discharge to reduce the swing ofblanket energy multiplication is efficient. |
