An expression of the likelihood that, given the way a reactor is designed and operated, an accident could cause the fuel in the reactor to be damaged.
At a nuclear facility, an area outside a restricted area but within the site boundary, to which the licensee can limit access for any reason.
A declaration, statement, or assertion of impropriety or inadequacy associated with NRC-regulated activities, the validity of which has not been established. For additional detail, see What is an Allegation.
Any given absorber that will reduce the intensity of an original beam of ionizing radiation to one-half of its initial value.
The maximum amount of electric energy that a generator can produce (from the mechanical energy of the turbine), adjusted for ambient conditions. Generator capacity is commonly expressed in megawatts (MW).
Exposure to ionizing radiation when the radiation source is located outside the body.
The area surrounding the reactor where the reactor licensee has the authority to determine all activities, including exclusion or removal of personnel and property.
A material, such as ordinary water, heavy water, or graphite, that is used in a reactor to slow down high-velocity neutrons, thus increasing the likelihood of fission.
(1) An atom that has too many or too few electrons, causing it to have an electrical charge, and therefore, be chemically active. (2) An electron that is not associated (in orbit) with a nucleus.

The ratio of the net electricity generated, for the time considered, to the energy that could have been generated at continuous full-power operation during the same period.
The Federal agency established by Congress to advance the national, economic, and energy security of the United States, among other missions.
The difference in pressure between two points of a system, such as between the inlet and outlet of a pump.
The gross maximum dependable capacity of the main generating unit in a nuclear power reactor, minus the amount used to operate the station. Net maximum dependable capacity is measured in watts unless otherwise noted.
In a pressurized water reactor, the coolant flow path through piping from the reactor pressure vessel to the steam generator, to the reactor coolant pump, and back to the reactor pressure vessel. Large PWRs may have as many as four separate loops.
A reactor that uses heavy water as its moderator. Heavy water is an excellent moderator and thus permits the use of unenriched uranium as a fuel.
An unit of energy equal to one watt of power steadily supplied to, or taken from, an electrical circuit for one hour (or exactly 3.6x103J).
A radioactive element that is one of the heaviest gases known. Its atomic number is 86. It is a daughter of radium.
A quantum (or packet) of energy emitted in the form of electromagnetic radiation. Gamma rays and x-rays are examples of photons.
A radionuclide that upon radioactive decay or disintegration yields a specific nuclide (the daughter).
