摘要/Abstract

摘要： 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。

Abstract: The radiation shielding performance measurements of transport container is the important content to ensure transportation safety of radioactive material. The radiation shielding performance of radioactive material package must meet the requirements of “Regulations for the safe transport of radioactive material” (GB 11806—2004). However, some of the problems and difficulties reflected in practice need to be solved, such as the measurement results of neutron radiation level of container outer are not always reliable. In this paper,the monitoring results of using both the neutron multi-sphere spectrometer and portable neutron measurement instrument are compared, and the MCNP runs are done to study the shielding performance measurements of spent fuel package. The results of monitoring and simulation are compared, some factors are discussed, and an optimized scheme is recommended.

Key words: radioactive materials transport package, spent fuel, neutron radiation monitoring, MCNP, shielding performance measurements
