摘要: 采用国际开源程序包Geant4，构建高能质子束轰击加速器驱动次临界系统(ADS) 散裂靶的物理模型，模拟计算质子轰击液态金属铅、铅-铋合金和汞靶的泄漏中子谱分布，以及计算不同能量质子对应的铅靶泄漏中子产额和轴向积分分布，获得1 GeV 质子对应的铅圆柱靶优化参数，考虑入射质子的利用率和整个堆芯的体积质量，优化靶半径范围为16 ~ 24 cm，靶高为100 cm，相关研究结果可为(ADS) 散裂靶的物理和工程设计提供理论依据。We use Geant4 toolkit to model high-energy proton irradiating spallation target in an Accelerator-Driven sub-critical System (ADS). The simulated neutron leakage spectrum resulting from proton bombarding liquid metal targets of lead, lead-bismuth eutectic, and hydrargyrum are obtained. The neutron leakage yields from lead target and their axial integrated distributions are calculated with different incident proton energies.Considering the incident proton efficiency and the whole size and mass of the reactor core, the optimized target radius and target height are suggested to be a range of 16~ 24 cm and 100 cm, respectively, which is helpful for the physical and engineering design of the ADS spallation target.
