加速器驱动的次临界系统散裂靶泄漏中子谱研究

Neutron Leakage Spectrum Study of Spallation Target of ADS

摘要: 为研究加速器驱动的次临界系统（ADS）散裂靶的散裂中子学特性，采用Geant4计算不同能量质子轰击铅铋靶产生的泄漏中子产额、能谱、轴向积分分布。模拟得到1 GeV质子对应的靶的优化尺寸及优化后泄漏中子谱，计算结果可为ADS散裂靶件和堆芯设计提供参考。

Abstract: To study the neutron leakage spectrum of spallation target of ADS, the neutron leakage spectrum of leadbismuth eutectic target with 1 GeV proton was simulated by Geant4 toolkit. The simulated neutron leakage spectrum and target optimization parameters, which will be beneficial to the reactor core design, are obtained.
