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.

The process of safely closing a nuclear power plant (or other facility where nuclear materials are handled) to retire it from service after its useful life has ended. This process primarily involves ...

declared pregnant woman

Energy; Nuclear energy

A woman who is an occupational radiation worker and has voluntarily informed her employer, in writing, of her pregnancy and the estimated date of conception (see 10 CFR 20. 1003 and 20. 1208).

decay heat

Energy; Nuclear energy

The heat produced by the decay of radioactive fission products after a reactor has been shut down.

daughter products

Energy; Nuclear energy

Isotopes that are formed by the radioactive decay of some other isotope. In the case of radium-226, for example, there are 10 successive daughter products, ending in the stable isotope lead-206.

curie (Ci)

Energy; Nuclear energy

cumulative dose

Energy; Nuclear energy

The total dose that an occupationally exposed worker receives as a result of repeated exposures to ionizing radiation to to the same portion of the body, or to the whole body, over time.
