A containment building is a meter-reinforced concrete container enclosing a nuclear power plant reactor. It has two main functions:
1- If all other safety systems fail, it will stop any radioactive release.
2- Protect against external influences in the form of earthquakes and plane crashes.
All reactors in the world are built with one. Only the Russian RBMK reactors (Chornobyl type) were built without such reactor containment.
Built and tested to withstand aircraft.
The reactor containments are some of the strongest man-made structures around.
It is built and tested to withstand aircraft. It was tested in April 1988 in a joint experiment between the U.S. government, Sandia Laboratories, and the Japanese Muto Institute of Structural Mechanics to test whether a reactor containment building would be able to withstand a kamikaze attack from a fully functioning F-4 Phantom jet that crashed into a 480.3-meter-reinforced thick concrete wall at a speed of 66 Mph. The test result was that the wall won while the aircraft was pulverized. The video shows the experiment.
