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
Radiology
Energy; Nuclear energy
That branch of medicine dealing with the diagnostic and therapeutic applications of radiant energy, including x-rays and radioisotopes.
Radiopharmaceutical
Energy; Nuclear energy
A pharmaceutical drug that emits radiation and is used in diagnostic or therapeutic medical procedures. Radioisotopes that have short half-lives are generally preferred to minimise the radiation dose ...

Reactor core
Energy; Nuclear energy
The central portion of a nuclear reactor, which contains the fuel assemblies, moderator, neutron poisons, control rods, and support structures. The reactor core is where fission takes place.
Reactor coolant system
Energy; Nuclear energy
The system used to remove energy from the reactor core and transfer that energy either directly or indirectly to the steam turbine.
Radioisotope
Energy; Nuclear energy
An unstable isotope of an element that decays or disintegrates spontaneously, thereby emitting radiation. Approximately 5,000 natural and artificial radioisotopes have been identified.
