Yet despite improvements in the design of nuclear-fission reactors, there remain public concerns about their safety and the waste that they produce. Many have suggested that harnessing nuclear ...

Nuclear fission does not release the greenhouse gas, carbon dioxide. A controlled nuclear fission reaction releases one million times more energy per kg than a chemical reaction such as burning ...

Drawing of the Chicago Pile-1 graphite-moderated fission reactor. What sometimes trips people up is that although both nuclear fission and nuclear fusion pertain to energy obtained from ...

Nuclear fission power plants have the disadvantage of generating unstable nuclei; some of these are radioactive for millions of years. Fusion on the other hand does not create any long-lived ...
