在核工业领域中,有些工程部件在服役过程中会诱发产生一定的放射性,具有放射性的样品在中子残余应力测试过程中首先要考虑辐射安全的问题。基于中子衍射实验技术和辐射安全要求,提出了一种反应堆监督样品中子残余应力测试分析的实验方法和流程。根据该方法和流设计加工了一套实用的屏蔽装置。该装置可以有效屏蔽样品的核辐射,满足一定辐射剂量的安全要求,同时满足中子衍射三维残余应力测量的基本实验要求。
In the field of nuclear industry, some engineering components induce some radioactivity during service. Radioactive samples must first consider the issue of radiation safety during neutron residual stress testing. Based on the neutron diffraction experiment and the radiation safety requirements, an experimental method and flow chart of the neutron residual stress testing and analysis of the reactor supervised sample is proposed. According to the method and flow design and processing a set of practical shielding device. The device can effectively shield the sample of nuclear radiation, to meet the safety requirements of a certain dose of radiation, while meeting the neutron diffraction three-dimensional residual stress measurement of the basic experimental requirements.
