Containment vs. Confinement
The International Atomic Energy Agency (IAEA) defines the Confinement as a prevention or control of releases of radioactive material to the environment in operation or in accidents.
Confinement is closely related in meaning to containment, but confinement is typically used to refer to the safety function of preventing the ‘escape’ of radioactive material, whereas containment refers to the means for achieving that safety function.
The Containment refers to methods or physical structures (e.g. the containment building) designed to prevent as low as reasonably achievable the dispersion of radioactive substances.
- Confinement. Confinement of radioactive material in operational states and in accident conditions.
- Protection. Protection of the power plant against external natural and human induced events
- Shielding. Radiation shielding in operational states and in accident conditions.
