There are a number of different nuclear fusion reactions happening in the Sun. The simplest is when four hydrogen nuclei become one helium nuclei.

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 ...

Yet despite improvements in the design of nuclear-fission reactors ... In a conventional reactor these neutrons are supplied by the fission reaction itself, which requires a certain concentration ...

A company aims to bring a nuclear fusion plant online in the early 2030s, but the path to this breakthrough is anything but easy.

In the sun, the extreme pressure produced by its immense gravity create the conditions for fusion to happen. The amount of energy produced from fusion is very large — four times as much as nuclear ...

Core nuclear reaction database containing evaluated cross sections, spectra, angular distributions, fission product yields, photo-atomic and thermal scattering law data, with emphasis on neutron ...

First, as the source of sustained nuclear fission, it provides information about how such processes occur independently of human interference. This has greatly assisted in streamlining models of ...

stopping the fission, before the water cooled and seeped into the deposits enough to begin the process again. Eventually, over thousands of years of nuclear reactions, the world's first (that we ...

Unlike chemical propulsion systems, nuclear thermal propulsion systems rely on nuclear fission reactions to heat the ...

Example nuclear reactions include radioactive decay, fission, the break-up of a nucleus, and fusion, the merging of nuclei. The semileptonic decay channels of the Λc baryon can give important ...
