摘要

核电是清洁的低碳能源，是实现我国2060年“碳中和”目标的重要技术选择，其放射性排放也是公众关注的焦点。该文通过构建统一的评价边界，采用生命周期评价（life cycle assessment，LCA）方法，分环节定量测算了核电与其他发电技术的单位发电量二氧化碳排放；并基于文献调研，分析和估算了单位发电量的大气污染物（SO2、NOx和PM2.5）和放射性排放；最后对不同发电方式的二氧化碳、大气污染物和放射性排放的环境影响进行综合评价。研究表明，核电和可再生能源发电可以使单位发电量碳排放降低90%以上，并大幅度减少大气污染物排放，而核电对公众的放射性影响与煤电相当，或低于煤电。因此，应大力加强核电的公众可接受性的科普教育，制定持续稳定的核能中长期发展战略，推动电力系统清洁低碳转型。

Abstract

Nuclear power is a clean, low carbon technology that will help China achieve carbon neutrality by 2060. However, the radiological impacts are also the focus of public concern. This study used the life cycle assessment (LCA) method to calculate the carbon dioxide emissions per unit electricity generated by nuclear power and other power generation technologies. This study also estimated the air pollutants and radiological impacts based on a literature review with a comprehensive assessment of these environmental impacts. The results show that nuclear power and renewable energy generation can reduce CO2 emissions per unit of electricity by more than 90% and greatly reduce air pollution. In addition, nuclear power has similar or lower radioactive impact on the public than coal power. Therefore, the government should strengthen public understanding and acceptance of nuclear power, formulate a long-term nuclear energy development strategy, and promote the clean, low-carbon transformation of the electric power system.
