核能发展蓝皮书

Abstract

Nuclear energy is an important area of strategic competition among the world’s
major powers. By the end of 2021, there were 442 nuclear power units in operation
worldwide, with a total installed capacity of more than 394 million kilowatts, distributed

in 32 countries or regions; 52 nuclear power units under construction, with a total
installed capacity of more than 55.087 million kilowatts, distributed in 19 countries or
regions. In the context of the increasingly urgent global response to climate change

and energy security issues, the advantages of nuclear energy in terms of cleanness, low-
carbon, safety and high effi ciency have become increasingly prominent. The world’s
major nuclear power countries continue to increase their investment in supporting

the research and development of third-generation nuclear power technology, small
modular reactors, fourth-generation nuclear energy systems and fusion technology.

World authoritative organizations such as the International Atomic Energy Agency and
the International Energy Agency predicted that the installed capacity of global nuclear
power will continue to increase in the future.
This report comprehensively presents the latest progress of China’s nuclear

energy development in 2021. As of the end of December 2021, the number of
commercial nuclear power units in China was 51, with a total installed capacity of

53.275 million kilowatts, ranking third in the world and accounting for 2.24% of the
country’s total installed power capacity; nuclear power generation was 407.141 billion
kilowatt hours, ranking second in the world, an increase of 11.17% compared to last
