Cross-cutting Area

Nuclear plant activity that affects most or all safety cornerstones. These include the problem identification and resolution, human performance, and "safety-conscious work environment."

Binding energy

The minimum energy required to separate the nucleus of an atom into its component neutrons and protons.

Crud

A colloquial term for corrosion and wear products (rust particles, etc.) that become radioactive (i.e., activated) when exposed to radiation.

Activity

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). For related information, see Measuring Radiation.

Heat sink

Anything that absorbs heat. It is usually part of the environment, such as the air, a river, or a lake.

Decay heat

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

Electron

An elementary particle with a negative charge and a mass 1/1837 that of a proton. Electrons surround the positively charged nucleus of an atom, and determine its chemical properties.

Neutron

An uncharged elementary particle, with a mass slightly greater than that of the proton, found in the nucleus of every atom heavier than hydrogen.

In vivo

From the Latin for "in one that is living," occurring within the living.

Generation (net)

The gross amount of electric energy produced by a generating station, minus the amount used to operate the station. Net generation is usually measured in watthours (Wh).

Detector

A material or device that is sensitive to ionizing radiation and can display its characteristics and/or produce a signal suitable for measurement or analysis. See also radiation detection instrument.

Dosimeter

A small portable instrument (such as a film badge, thermoluminescent dosimeter, or pocket dosimeter) used to measure and record the total accumulated personal dose of ionizing radiation. For additional information, see Detecting Radiation.

Capacity

The amount of electric power that a generator, turbine, transformer, transmission, circuit, or system is able to produce, as rated by the manufacturer.

Coastdown

An action that permits the reactor power level to decrease gradually as the fuel in the core is depleted.

Calibration

The adjustment, as necessary, of a measuring device such that it responds within the required range and accuracy to known values of input.

British thermal unit (Btu)

The amount of heat required to change the temperature of one pound of water one degree Fahrenheit at sea level.

Biological shield

A mass of absorbing material placed around a reactor or radioactive source to reduce the radiation to a level safe for humans.

Core melt accident

An event or sequence of events that result in the melting of part of the fuel in the reactor core.
