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.

roentgen equivalent man (REM)
Energy; Nuclear energy
One of the two standard units used to measure the dose equivalent (or effective dose), which combines the amount of energy (from any type of ionizing radiation that is deposited in human tissue), ...
risk-based decisionmaking
Energy; Nuclear energy
An approach to regulatory decisionmaking that considers only the results of a probabilistic risk assessment.
risk
Energy; Nuclear energy
The combined answer to three questions that consider (1) what can go wrong, (2) how likely it is, and (3) what its consequences might be. These three questions allow the NRC to understand likely ...
restricted area
Energy; Nuclear energy
Any area to which access is controlled for the protection of individuals from exposure to radiation and radioactive materials.
renewable resources
Energy; Nuclear energy
Natural, but limited, energy resources that can be replenished, including biomass, hydro, geothermal, solar, and wind. These resources are virtually inexhaustible but limited in the amount of energy ...
reflector
Energy; Nuclear energy
A layer of material immediately surrounding a reactor core that scatters back (or reflects) into the core many neutrons that would otherwise escape. The returned neutrons can then cause more fissions ...
reference man
Energy; Nuclear energy
A person with the anatomical and physiological characteristics of an average individual that is used in calculations assessing internal dose (also may be called "standard man").
