This process involves splitting atoms of Uranium-235, a heavy and unstable isotope, in a controlled chain reaction. Nuclear power is considered clean energy because it does not produce air pollutants. The resulting nuclear waste, however, poses significant disposal challenges due to its long-lasting radioactivity.
