Abstract: Vigorously promoting green and low-carbon energy is the energy development strategy in China. As an efficient and clean new energy，nuclear energy has great potential in district heating in China，since it can greatly alleviate current environmental pollution problems caused by coal-fired district heating systems. Analyzing the necessity of nuclear energy district heating systems in China，the time is ripe for developing it. From the viewpoints on the inherent safety of representative nuclear heating reactor designs in China，the economic and social value of nuclear energy district heating systems，the possibility of performance improvement for the system integrated with pipeline flow turbulent drag reduction technology，system optimization based on deep learning，heat supply with multiple heat sources，phase change heat storage and big data smart heat supply technology is expounded.The advantages of nuclear energy district heating system are fully elaborated，which provides support for the promotion of nuclear energy district heating technology.
