A controlled nuclear fission reaction releases one million times more energy per kg than a chemical reaction such as burning coal, oil or gas. This means much less fuel is required than for a ...

Both fusion and fission reactions shift the size of the reactant nuclei towards higher bounded nuclei. Does Fusion produce radioactive nuclear waste the same way fission does? Nuclear fission power ...

Scientists have discovered that a piece of uranium extracted from an African mine is a two billion-year-old natural nuclear ...

The amount of energy produced from fusion is very large — four times as much as nuclear fission reactions — and fusion reactions can be the basis of future fusion power reactors. Plans call for ...

However, Bill Gates, who has invested significantly in both nuclear fission and fusion startups ... form a heavier one while ...

Many of the features of the reactor are designed to control the speed of the reaction and the temperature inside the shielding. An uncontrolled fission reaction is the basis of an atomic bomb.

By the end of the year the physicist Werner Heisenberg had calculated that nuclear fission chain reactions might be possible. When slowed down and controlled in a "uranium machine" (nuclear ...

In a conventional reactor these neutrons are supplied by the fission reaction itself, which requires a certain concentration of the correct fissile isotopes (typically 235 U or 239 Pu) to be ...

Scientists have succeeded in maintaining an "artificial sun" here on Earth for a whopping 17 minutes and 46 seconds.
