Clean energy complementary system can reduce environmental pollution effectively and is considered as a future energy development direction. In this paper, an innovative solar-nuclear thermally coupled power and desalination plant for electricity and freshwater productions is proposed. As solar power and nuclear power are combined, this multi-energy system is a clean energy system and basically has no emissions of soot, sulfur oxides, carbon dioxide, and nitrogen oxides. The operating behavior assessment results of the multi-energy system show that the power generation and freshwater production systems can operate synergistically. The electric power and corresponding efficiency of the multi-energy system are 290.7 MW and 38.2%, in which the solar proportion is about 38.1%. The daily freshwater production of the multi-energy system is 3761.3 t. The economic assessment results reveal that the levelized costs of electricity and freshwater of the multi-energy system are 0.361 yuan/(kWh) and 1.645 yuan/t. The environmental protection analysis results show that in contrast with a coal-fired system, the annual emission reductions of soot, sulfur oxides, carbon dioxide, and nitrogen oxides of the multi-energy system are 7350.94 t, 12,634.42 t, 513,034.14 t, and 11,945.28 t, revealing a significant environmental protection performance.
清洁能源互补系统可以有效减少环境污染，被认为是未来能源发展的方向。本文提出了一种创新的太阳能-核能热耦合发电和海水淡化厂，用于电力和淡水生产。由于太阳能和核能的结合，这个多能源系统是一种清洁能源系统，基本上没有烟尘、硫氧化物、二氧化碳和氮氧化物的排放。多能源系统的运行行为评估结果表明，发电和淡水生产系统可以协同运行。多能源系统的电力和相应效率为 290.7MW 和 38.2%，其中太阳能的比例约为 38.1%。多能源系统的日淡水产量为 3761.3 吨。经济评估结果显示，多能源系统的平准化发电成本和淡水成本分别为 0.361 元/(千瓦时)和 1.645 元/吨。环境保护分析结果表明，与燃煤系统相比，多能源系统的烟尘、硫氧化物、二氧化碳和氮氧化物年排放量分别减少了 7350.94 吨、12634.42 吨、513034.14 吨和 11945.28 吨，具有显著的环保性能。
