摘要
聚变-裂变混合能源堆包括聚变中子源和以天然铀为燃料、水为冷却剂的次临界包层,主要目标是生产电力。利用输运燃耗耦合程序系统MCORGS计算了混合能源堆一维模型的燃耗,给出了中子有效增殖因数keff、能量放大倍数M、氚增殖比TBR等物理量随时间的变化。通过分析能谱和重要核素随燃耗时间的变化,说明混合能源堆与核燃料增殖、核废料嬗变混合堆的不同特点。本文给出的结果可作为混合堆中子输运、燃耗分析程序校验的参考数据,为混合堆概念研究提供了基础数据。
Fusion-fission hybrid energy reactor is driven by Tokamak fusion source for energy production.Its subcritical zone uses the natural uranium as fuel and water as coolant.The neutron multiplication constant keff,energy multiplication factor M and tritium breeding ratio TBR of the 1D hybrid energy reactor model were calculated by transport burnup code MCORGS.The neutron spectrum and nuclear density changing as a function of time show the characteristics of the hybrid energy reactors,which differs from the hybrid reactor for breed nuclear fuel and for spent fuel transmutation.The definition and results may be a reference to the other conceptual analysis.
