A nuclear reactor is driven by the splitting of atoms, a process called fission, where a particle (a ‘neutron’) is fired at an atom, which then fissions into two smaller atoms and some additional neutrons. Some of the neutrons that are released then hit other atoms, causing them to fission too and release more neutrons. Molten salt reactors are nuclear's future, but there's still a lot we don't know. A new breakthrough could help engineers crack the next phase of nuclear energy.Nuclear Fusion reactions power the Sun and other stars.
