摘　　要：计算分析"快-热"耦合加速器驱动次临界实验装置"启明星1#"在252Cf、Am-Be和氘-氚(2H-3H)中子源驱动下,单向耦合时快区泄漏中子数、净中子产额和泄漏中子谱随快区层数与外中子源能量的变化关系。结果表明,从反应堆产能和嬗变角度考虑,"启明星1#"实验装置快区燃料元件单向耦合时存在最优化的元件装载量。VENUS 1# was the first fast-thermal coupled accelerator driven sub-critical experimental facility of the world built by China Atomic Energy Institute-CIAE.In this paper,the leakage and net neutron yield of fast zone and leakage neutron spectrum driven by 252Cf,Am-Be and D-T neutron sources with different loading layers was calculated based on VENUS 1# unidirectional coupling mode.The results show that,from the view of energy production and transmutation,there exists optimized fuel loadings of fast-zone,which will provide theoretical basis for designing ＂fast-thermal＂ unidirectional coupling systems.
