kärncontainment

Kärncontainment, also known as nuclear containment, refers to the engineering design and construction of structures and systems intended to prevent the release of radioactive materials from a nuclear reactor in the event of an accident. The primary goal of nuclear containment is to maintain the integrity of the reactor core and prevent the spread of radiation to the environment.

Nuclear containment structures are typically designed to withstand extreme conditions, including high temperatures, pressures, and impacts. They are usually made of reinforced concrete or steel, and are equipped with various safety systems, such as emergency cooling systems and pressure relief valves, to manage and mitigate the effects of an accident.

The effectiveness of nuclear containment is crucial for ensuring public safety and environmental protection. In the event of a severe accident, such as a meltdown, the containment structure is designed to limit the release of radioactive materials and prevent them from dispersing into the surrounding environment. This is achieved through a combination of physical barriers, such as the containment walls and roof, and active safety systems, such as ventilation and filtration systems.

Nuclear containment is a critical component of nuclear power plant design and regulation. It is subject to stringent safety standards and regulations, such as those established by the International Atomic Energy Agency (IAEA) and national regulatory bodies. The design and construction of nuclear containment structures are subject to rigorous testing and inspection to ensure their reliability and effectiveness in preventing the release of radioactive materials.
