聚变驱动乏燃料焚烧堆氦冷包层中子学设计与分析

Neutronics analysis on helium-cooled blanket of a fusion-driven spent fuel burner

采用VisualBUS程序和HENDL数据库,对聚变驱动乏燃料焚烧堆氦冷包层开展了中子学设计与分析工作,设计目标是在满足Keff小于0.95,功率密度小于100MW.m-3和氚自持的前提下,获得至少1GWe的能量输出和最大增殖、嬗变能力,且系统能够连续稳定运行。文中通过对包层中的乏燃料成分和是否装载贫铀开展优化分析并给出了优化方案,该方案能够很好地满足设计目标。

Neutronics design and analysis of helium-cooled spent fuel burning blanket for a fusion driven sub-critical system are performed to ensure the system be able to meet the requirements of energy production （〉 1 GWe）, more fuel breeding, more waste transmutation and long period run with deep subcritical （Keff 〈 0.95）, tritium sustainable,reasonable power density （〈100 MW . m^-3） ,which is based on 1-D burnup calculations with home-developed code VisualBUS and the data library HENDL.
