MOX fuel rod end plug marking method

The invention provides an MOX fuel rod end plug marking method, which comprises the steps: cleaning an end plug; marking a digital code; and marking bar code, and carrying out other steps. According to the invention, the digital code and the bar code are marked on the MOX fuel rod end plug at the same time, so that automatic recording of coded information in the fuel rod production process is achieved under the hot chamber shielding condition that manual intervention is inconvenient and direct, production information recording and material tracking are facilitated, the material circulation efficiency of the MOX fuel rod production line is improved, and the production efficiency is indirectly improved. 本发明提供了一种MOX燃料棒端塞打标方法，包括清洁端塞；标刻数字码；标刻条形码等步骤。本发明通过在MOX燃料棒端塞上同时标刻数字码与条形码，在人工不方便直接干预的热室屏蔽条件下实现了燃料棒生产过程中的编码信息自动记录，方便了生产信息记录及物料跟踪。提高了MOX燃料棒生产线物料流转效率，间接提高了生产效率。
