中子辐射水平测量的可靠性是辐射屏蔽性能检测的难点。本文采用便携式中子测量仪和多球谱仪对某型乏燃料运输货包外部中子辐射水平进行了测量,并基于SCALE程序计算得到的乏燃料中子源项,采用MCNP程序模拟计算得到货包外部中子辐射水平。对测量结果和计算结果进行比较,分析相关影响因素,提出了优化测量方案的建议。
The measurement of neutron radiation level reliability is the difficulty of radiation shielding performance testing. In this paper, the neutron radiation level of a spent fuel transport package was measured by portable neutron meter and multi-ball spectrometer, and the spent fuel neutron source term was calculated based on SCALE program. External neutron radiation levels. The measurement results and the calculation results are compared to analyze the related factors, and the suggestions for optimizing the measurement scheme are put forward.
