After the heavy blow of Fukushima nuclear accident in Japan, nuclear power has gradually embarked on the road of recovery, and the increasingly serious energy and environmental crisis has prompted nuclear power to reproduce its advantages as a clean energy source. Nuclear power will continue to play an important role in the future world's low-carbon energy. At the same time, after years of technological development, the safety and reliability of nuclear power have been further improved. The advanced light water reactor nuclear power plants developed by the United States, Europe and Japan, that is, the "third generation" nuclear power plants, have made great progress, and some of them have been put into commercial operation or will be established soon. Nuclear power, as a safe, reliable and mature clean energy and the only clean energy that can replace fossil fuels on a large scale, has attracted more and more attention from all countries in the world.
More than 30 countries or regions in the world have built nuclear power plants. According to the statistics of the International Atomic Energy Agency, by the end of 20 12 and 12, there were 437 nuclear power units in operation, with a total installed capacity of about 370 million kilowatts. Nuclear power plants are mainly distributed in the United States and Canada in North America; France, Britain, Russia, Germany in Europe and some industrialized countries such as Japan and South Korea in East Asia. Among them, USA 104, France 58, Japan 50, Russia 33, South Korea 23, India 20 and Canada 19. Nuclear power accounts for about 15% of the world's total power generation. According to the statistics of 2065,438+065,438+0 published by the International Atomic Energy Agency, the global nuclear power generation accounts for 77.7% in France, 34.6% in South Korea, 65,438+08.1%in Japan and 65,438+09.2% in the United States. There are 68 nuclear power units under construction in the world, with an installed capacity of about 70.69 million kilowatts, of which more than 70% are concentrated in China, India in Asia and Russian countries in Europe.
Considering environmental protection, ecology and world energy supply, nuclear power, as a safe, clean, low-carbon and reliable energy source, has been accepted and adopted by more and more countries, which has set off a nuclear power construction boom in some parts of the world. Nowadays, more and more countries are considering or initiating plans to build nuclear power plants, and more than 60 countries are considering using nuclear energy to generate electricity. By 2030, it is estimated that 10-25 countries will join the nuclear power club and build new nuclear power units. According to the prediction of the International Atomic Energy Agency, by 2030, the global installed nuclear power capacity will increase by at least 40%.
