摘　　要：先进的球环型氚生产聚变堆是聚变能发展的中间应用产物。与传统托卡马克氚生产堆不同,在设计中利用了球形环的先进等离子体物理性能,并具有紧凑的结构特征,尽量利用真空室内的空间安置氚生产包层以减少氚泄露而增加氚增殖率,达到年生产富余氚1kg的目的,相应的堆利用因子为40%。在二维中子学计算的基础上,提出了ST TPR的初步概念设计,为下一步更详细具体的概念设计提供了直接的依据和重要的参考价值。Conceptual design of an advanced tritium production fusion reactor based on spherical torus,which is intermediate application of fusion energy,was presented in this paper.Differing from the traditional tokamak tritium production reactor design,advanced plasma physics performance and compact structural characteristics of ST were used to minimize tritium leakage and maximize tritium breeding ratio with arrangement of tritium production blankets within vacuum vessel as possible in order to produce 1kg excess tritium except need of self-sufficient plasma core with 40% or more corresponding plant availability.Based on 2D neutronics calculation,preliminary conceptual design of ST-TPR was presented,providing the backgrounds and reference for next detailed conceptual design.
