World Nuclear Association: • Nuclear power capacity worldwide is increasing steadily, with about 50 reactors under construction. • Most reactors on order or planned are in the Asian region, though there are major plans for new units in Russia. • Significant further capacity is being created by plant upgrading. • Plant lifetime extension programs are maintaining capacity, particularly in the USA. There are about 450 nuclear power reactors operating in 30 countries plus Taiwan, with a combined capacity of over 390 GWe. In 2015 these provided about 11% of the world's electricity. About 50 power reactors are currently being constructed in 13 countries, notably China, India, UAE and Russia.
China has 936 GWe, India 215 GWe, the world more than 1,373 GWe of coal plant capacity. In the next half century, more nuclear power capacity will be retired without replacement than new capacity added except in Russia, China and maybe India. Countries with exemplary nuclear power programs like Switzerland have decided to discontinue use of nuclear power as their plants reach end of life. Energy experts are at a complete loss of what Switzerland will do.
