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.

airborne radioactivity area

Energy; Nuclear energy

The airborne radioactivity area is a room, enclosure, or area in which airborne radioactive materials, composed wholly or partially of licensed material, exist in concentrations that (1) exceed the ...

agreement state

Energy; Nuclear energy

A State that has signed an agreement with the NRC authorizing the State to regulate certain uses of radioactive materials within the State.

air sampling

Energy; Nuclear energy

The collection of samples of air to measure the radioactivity or to detect the presence of radioactive material, particulate matter, or chemical pollutants in the air.

activity

Energy; Nuclear energy

The rate of disintegration (transformation) or decay of radioactive material per unit time. The units of activity (also known as radioactivity) are the curie (Ci) and the becquerel (Bq).

Energy; Nuclear energy

The end-to-end dimension of fuel material within a fuel assembly (also known as a "fuel bundle" or "fuel element").

activation

Energy; Nuclear energy

The process of making a radioisotope by bombarding a stable element with neutrons or protons.

access hatch

Energy; Nuclear energy

An airtight door system that preserves the pressure integrity of the containment structure of a nuclear reactor, while allowing access to personnel and equipment.
