Nuclear fission—when the nucleus of an atom ... starting from the capture of the incident neutron and formation of the compound nucleus, until all fission fragments have been emitted.

Most new nuclear fission reactors being built today are of the light water reactor (LWR) type, which use water for neutron moderation into thermal neutrons as well as neutron capture. While ...

This is quite unlike 235 U, which has a solid fission cross section, but only at neutron speeds which are significantly lower than those of freshly emitted neutrons during the nuclear chain reaction.

was to create a controlled nuclear reaction; that is, to split the atom without creating a deadly explosion. Theoretically, it was possible. During fission, a fast-moving neutron splits an atom's ...

What’s the difference between nuclear fission and nuclear fusion ... The activation of the reactor’s structural material by intense neutron fluxes is another issue. This strongly depends on what ...

In addition, two or three neutrons ... nuclear reactor, which can then be used to heat water to drive the turbines that turn the generators to generate electricity. A controlled nuclear fission ...

Usually, you can only cram so many neutrons into a nucleus before it just falls apart, due to the repulsive effects of the ...
