球环型产氚聚变堆概念设计研究

该研究基于球环类型的先进氚生产堆概念而设计,是聚变能发展的中间应用。与传统托卡马克氚生产堆不同,该设计利用球形环的先进等离子体物理性能和紧凑的结构特征,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,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较为完整的初步概念设计。在逐项分析的基础上对设计的风险、不确定性和后备方案也做了概括的解释。为下一步更详细具体的概念设计提供了直接的依据,具有重要的参考价值。

A Study on Conceptual Design of Tritium Production Fusion Reactor Based on Spherical Torus(In Chinese)

Conceptual design of an advanced tritium production reactor based on spherical torus (ST), which is an intermediate application of fusion energy, is presented. Different from traditional Tokamak tritium production reactor design, advanced plasma physics performance and compact structural characteristics of ST are used to minimize tritium leakage and to maximize tritium breeding ratio with arrangement of tritium production blankets as possible as it can do within vacuum vessel in order to produce certain amount of excess tritium except self-sufficient plasma core, corresponding plant availability 40% or more. Based on 2D neutronics calculation, preliminary conceptual design of ST-TPR is presented. Based on systematical analysis, design risk, uncertainty and backup are introduced generally for the backgrounds of next detailed conceptual design.
