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.
The World Nuclear Association Weekly Newsletter for February 23, 2018 reports that the USA is going to start research on fast reactors again. The United States had a tremendous lead in the 1970s. Presidents Carter and Clinton, President Obama's Science Advisor John Holdren, Natural Resources Defense Council's Thomas Cochran, and Princeton's Frank Von Hippel worked hard to close fast reactors in the USA. The United States may restart research on fast reactors after losing three decades of progress to the Russians and Chinese. Good for Russia and China. Very unfortunate for the USA. The world needs all the energy that it can get from fossil fuels and nuclear. With no false obstacles in the way, the USA could be self-sufficient and an exporter of energy and energy technologies to make a better world for people and nature.
World Nuclear Association: Slovakia has four nuclear reactors generating half of its electricity and two more under construction. Slovakia's first commercial nuclear power reactor began operating in 1972. Government commitment to the future of nuclear energy is strong.
World Nuclear Association: This paper focuses on advanced designs in the small category, i.e. those now being built for the first time or still on the drawing board, and some larger ones which are outside the mainstream categories dealt with in the Advanced Nuclear Power Reactors information paper. Note that many of the designs described here are not yet actually taking shape. Four main options are being pursued: light water reactors, fast neutron reactors, graphite-moderated high temperature reactors and various kinds of molten salt reactors (MSRs). The first has the lowest technological risk, but the second (FNR) can be smaller, simpler and with longer operation before refueling. Some MSRs are fast-spectrum.
