摘要
利用MCNP程序对加速器驱动次临界系统(ADS)堆芯设计进行验证。在确定堆芯尺寸的情况下,当ADS的靶源和冷却剂是铅、铅-铋合金、铋和汞时,通过MCNP程序进行模拟计算得到相应的keff值、中子能谱和中子通量密度;并对铅、铅-铋合金、铋和汞的数据进行对比分析。结果表明,铅-铋合金是ADS系统的最佳材料,根据相应数据,提出堆芯设计的优化方案。
In this paper, some characteristics of the ADS subcritical reactor core is described using the Monte Carlo code（MCNP）. The keff value, neutron energy spectrum and neutron flux of a ADS system are obtained by the MCNP code under certain ADS core size as the ADS target and coolant are lead, lead-bismuth alloy, bismuth and mercury respectively. The data and the ADS system parameters obtained from the MCNP simulation calculation are compared and analyzed. The results show that the lead-bismuth alloy is the best material for ADS target and coolant among all the materials tested.
