  • 摘要: 用小型贫化铀裂变室和俘获探测器测量了D T聚变中子在碳材料反射体上反射中子引起的238U裂变反应率分布。比较了无碳材料反射体的测量结果。实验测得的238U裂变反应率合成不确定度为5.1%~6.4%。实验结果与用MCNP/4A程序和ENDF/B Ⅳ库数据计算的结果在误差范围内符合。

     

    Abstract: To check the data of carbon material reflecting neutrons, the distribution of238U fission reaction rates induced by DT fusion neutrons reflected by carbon material was measured by using the small depleted uranium fission chamber and the capturing detector. For comparison,238U fission rates without carbon material was measured too. The combined standard uncertainty of238U fission reaction rate is 5.1%~6.4%. The measured results are consistent with the calculated ones with MCNP/4A code and ENDF/BⅣ library data in the range of the error.
