As of 2015, there are five new reactors under construction with a gross electrical capacity of 6,218 MW, while 33 reactors have been permanently shut down. The United States is the world's largest supplier of commercial nuclear power, and in 2013 generated 33% of the world's nuclear electricity.here has been considerable opposition to the use of nuclear power in the U.S. The first U.S. reactor to face public opposition was Fermi 1 in 1957. It was built approximately 30 miles from Detroit and there was opposition from the United Auto Workers Union.
The energy produced by nuclear energy power plants is measured in megawatts. The United States tops the list with more than 101 megawatts of power produced. This is roughly one-fourth of the total nuclear energy produced in the world.France follows at a far second with energy output of 63 megawatts. Japan takes the third place followed by Russia and Germany, which completes the list of the top five countries that produce electricity from nuclear energy power plants.he radioactive waste takes years to be no longer hazardous. In addition there is a risk of a nuclear accident like the one at Chernobyl. In spite of that, with the help of modern technology many countries use nuclear power plants to generate electricity and the number of nuclear power plants is increasing every year.
