Nuclear energy provides a sustainable solution for energy production. It works by using nuclear reactions in atomic cores made of protons and neutrons to generate electricity. The key advantages are that it is a clean energy source with a low carbon footprint that produces reliable baseload power with less waste than other sources. However, major accidents like Three Mile Island, Chernobyl, and Fukushima demonstrate the risks of radioactive impacts and environmental damage from losses of containment. Nuclear energy also has high costs compared to other sources.
