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 ...

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 ...

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.

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 ...

The company, Deep Fission, signed a deal on Tuesday with data center developer Endeavour to build 2 gigawatts’ worth of subterranean nuclear power. As part of the deal, Endeavour invested in the ...
