从人员投入、占用时间、现场实施、成本投入等方面对数字射线成像（DR）技术和胶片射线检测技术在核电厂大修检测的实际应用情况进行了能效对比，为数字射线成像技术在核电领域的进一步应用提供支撑。通过数据分析可知，DR检测技术的应用还有较大的提升空间，但是在很长的一段时间内，DR检测技术和胶片检测技术仍将并行存在，相辅相成。

This paper compares the energy efficiency of digital ray imaging (DR) technology and film ray detection technology in nuclear power plants from the aspects of personnel input, occupation time, field implementation and cost input, so as to provide support for the further application of digital ray imaging technology in nuclear power. Through data analysis, it is concluded that there is still a large room for the promotion and application of DR detection technology, but in a long period of time, DR detection technology and film detection technology will still exist in parallel and complement each other.
