nu·cle·ar re·ac·tion

the interaction of two atomic nuclei or of one such with a subatomic particle, or of the subatomic particles within an atomic nucleus, resulting in a change in the nature of the nuclei concerned or in the energy content of the nuclei or both, usually manifested by transmutation (accompanied by emission of alpha-, beta-, and/or gamma-rays) or by fission or fusion of the nuclei.

Liquid-fuel molten-salt reactors are also inherently safer because as the liquid heats up, it expands, slowing the nuclear reactions. In addition, the reactor is built with a drain plug, kept solid by an electric cooler in the bottom.

The practical use of nuclear reactions requires a considerable numerical input that describes properties of the nuclei and interactions involved.
In the Fukushima accident, nuclear reactions were stopped immediately after the powerful earthquake.
"For the same neutron flux, you can have a much smaller detector yet still count the same number of neutrons coming in because of the high density" of boron atoms for nuclear reactions, said McGinnis.
These elements were obtained as a result of nuclear reactions. As is seen, all deviations in this region are negative: this can mean a large deficiency of the numerical values of the atomic masses obtained in the nuclear synthesis producing these elements, incorrect calculations, or a lack of neutrons in the nuclei.
The temperature leaps and nuclear reactions blow the entire star to smithereens.
He includes chapters on nuclear reactions and types of reactors, which he says are useful for people entering the nuclear workforce.
By closely examining hadronic masses that are both stable and non-stable, this volume is able to expand this framework to apply to such intense phenomena as black holes and nuclear reactions.
There is a flaw in what your correspondent Bert Ward writes (Nuclear Reactions, 19.12.06).
The experimental reactor will attempt to reproduce on Earth the nuclear reactions that power the Sun andother stars.
According to Wired, "EPRI concluded: 'Small but definite evidence of nuclear reactions have been detected at levels some 40 orders of magnitude greater than predicted by conventional nuclear theory.'" Two years later a NASA technical memo suggested similar results had been obtained by the space agency.
