摘要
钚裂变率实验是中子模拟工程中需要重点关注的对象。根据理论研究需求,用~(252)Cf中子源和钚裂变电离室,开展了纯水泥反射体内反射中子的钚裂变反应率实验研究,实验结果不确定度为10.5%。实验结果与理论模拟计算进行了比较,两者在不确定度范围内符合。实验研究结果为理论分析提供参考。
Plutonium fission reaction rates are an important issue for the neutron engineering simulation.According to the needs of the theoretical research,the plutonium fission reaction rate experiments of the reflex neutrons inside a pure cement reflector were carried out using a ~(252)Cf neutron source and a plutonium fission chamber.The results under this experimental model exhibit an uncertainty of 10.5%,which are in general agreement with the theoretical simulation.The experimental results are able to provide references for the theoretical analysis.
