| 摘 要： | 为满足中国聚变工程实验堆(CFETR)包层的应用要求,本文提出氦冷陶瓷增殖(HCCB)包层方案。为验证HCCB包层设计方案的合理性与可行性,采用三维蒙特卡罗粒子输运程序MCNP,计算和分析了HCCB包层方案的氚增殖比、中子壁负载、中子通量密度、核热、辐照损伤等中子学特性。结果表明,HCCB包层方案满足氚自持要求,中子通量密度和核热分布合理,屏蔽性能良好,基本满足设计要求。

| Abstract: | For meeting the application requirements of China Fusion Engineering Test Reactor (CFETR)blanket,the helium cooled ceramic breeder (HCCB)blanket concept was proposed in this paper.In order to verify the rationality and feasibility of HCCB blanket scheme,the neutronics characteristics including tritium breeding ratio,neutron wall loading, neutron flux density, nuclear power and irradiation damage were calculated with the three-dimensional Monte Carlo particle transport code MCNP.The results show that the HCCB blanket scheme satisfies the requirements of tritium self-sustaining,its neutron flux density and nuclear power distributions are reasonable,and the shield meets the design requirements well. |
