What is Nuclear Power? This site focuses on nuclear power plants and nuclear energy. The primary purpose is to provide a knowledge base not only for experienced.

In general, gamma spectroscopy studies the energy spectra of gamma-ray sources, such as in the nuclear industry, geochemical investigation, and astrophysics. Spectroscopes, or spectrometers, are sophisticated devices designed to measure the spectral power distribution of …

The bremsstrahlung is electromagnetic radiation produced by the acceleration or deceleration of a charged particle when deflected by magnetic fields (an electron by a magnetic field of particle accelerator ...

The neutron emission process is controlled by the nuclear force and therefore is extremely fast, sometimes referred to as “nearly instantaneous.” The ejection of the neutron may be a product of the movement of many nucleons.

Internal conversion is an electromagnetic process by which an excited nuclear state decays by the direct emission of one of its atomic electrons.

The law requires that during any nuclear reaction, radioactive decay or chemical reaction in an isolated system, the total mass of the reactants or starting materials must be equal to the mass of the products.

The definitions described above are fully applicable to a reactor at zero power level, that is, at such a power level. All thermal considerations are unimportant to the chain reaction (from zero power to 1% of rated power). See also: Criticality of Power Reactor

Especially energetic alpha particles (except artificially accelerated helium nuclei) are produced in a nuclear process known as ternary fission. In this process, the uranium nucleus is split into three charged particles (fission fragments) instead of the normal two.

In modern nuclear power plants, the overall thermal efficiency is about one-third (33%), so 3000 MWth of thermal power from the fission reaction is needed to generate 1000 MWe of electrical power. The reason lies in relatively low steam temperature (6 MPa; 275.6°C).

Its members are produced artificially by nuclear reactions and do not occur naturally because the half-life of the longest-lived isotope in the series is short compared to the age of the Earth. This radioactive decay chain consists of unstable heavy atomic nuclei that decay through a sequence of alpha and beta decays until a stable nucleus is ...
