The development of nuclear energy is significant for optimizing our energy structure，building a beautiful China and a strategic choice for tackling global climate change. The 14th Five-Year Plan period is an important period of strategic opportunities for the development of the nuclear energy industry. In 2019，the scale of nuclear power units in commercial operation continues to grow，and the nuclear power units under construction advance steadily. By the end of 2019，China had 47 nuclear power units in commercial operation with installed capacity of 48715 MWe，ranking third in the world；13 units under construction with installed capacity of 13871 MWe，ranking first in the world. The report will describe the current situation of nuclear power production operation and construction management in China in terms of the number and installed capacity of nuclear power units，the cumulative operating time of nuclear power equipment，the WANO performance indicators for nuclear power units，and the general situation of construction projects.
