Nuclear energy

Nuclear energy

Nuclear binding energy is the energy required to split a nucleus of an atom into its component parts. The component parts are neutrons and protons, which are collectively called nucleons. The binding energy of nuclei is always a positive number, since all nuclei require net energy to separate them into individual protons and neutrons.

Nuclear energy

Dose rate

Energy; Nuclear energy

The dose of ionising radiation delivered per unit time. For example, rems or sieverts (Sv) per hour.

Dose equivalent

Energy; Nuclear energy

A measure of the biological damage to living tissue as a result of radiation exposure. Also known as the " biological dose," the dose equivalent is calculated as the product of absorbed dose in ...

Dose

Energy; Nuclear energy

A general term, which may be used to refer to the amount of energy absorbed by an object or person per unit mass. Known as the "absorbed dose," this reflects the amount of energy that ionising ...

Doppler coefficient

Energy; Nuclear energy

Another name used for the "fuel temperature coefficient of reactivity," or the change in reactivity per degree of change in the temperature of nuclear fuel. The physical property of fuel pellet ...

Differential pressure (dP)

Energy; Nuclear energy

The difference in pressure between two points of a system, such as between the inlet and outlet of a pump.

Film badge

Energy; Nuclear energy

Photographic film used to measure exposure to ionising radiation for purposes of personnel monitoring. The film badge may contain two or three films of differing sensitivities, and it may also ...

Fertile material

Energy; Nuclear energy

A material, which is not itself fissile (fissionable by thermal neutrons), that can be converted into a fissile material by irradiation in a reactor. There are two basic fertile materials: ...
