Nuclear energy is a form of power generated through the process of nuclear fission, where the nucleus of an atom, typically uranium or plutonium, is split into smaller parts. This reaction releases a significant amount of energy, which is then used to heat water, producing steam that drives turbines to generate electricity. Nuclear power plants are designed to harness this energy efficiently and safely. One of the main advantages of nuclear energy is that it produces large amounts of electricity with low greenhouse gas emissions, making it a cleaner alternative to fossil fuels. However, it also raises concerns about radioactive waste, nuclear accidents, and the potential for nuclear proliferation.
