Detailed explanation-1: -’Renewable’ energy refers to energy from sources that are constantly replenished-like the water for hydroelectric dams that is topped up by the rain, or the sunlight that reappears every day for solar panels. Because nuclear power uses up radioactive fuel, it is not renewable in the same way.
Detailed explanation-2: -Although nuclear power is not a renewable energy, it is still recyclable. Thanks to Orano’s technologies, unique in the world on an industrial scale, 96% of spent nuclear fuel in reactors is recyclable.
Detailed explanation-3: -Rare in its natural state, uranium-235 is a nonrenewable resource, although small quantities go a long way. For example, the fission of one pound of uranium releases more energy than burning three million pounds of coal. Nuclear fission reactors split atoms to release the energy from the nucleus of enriched uranium.
Detailed explanation-4: -Is nuclear energy renewable? Nuclear fuels, such as the element uranium, are not considered renewable as they are a finite material mined from the ground and can only be found in certain locations.
