The structural integrity of these buildings is strictly monitored and tested, and they must meet leak requirements in the case of an accident.

Internal failures that must be addressed include:<ref name=iaea/>

*Loss of coolant accidents (LOCA),
*Breaks in steam or feedwater piping,
*Fires or flooding,
*Ruptured pressure tubes in [[pressurized water reactor]]s,
*Fuel handling accidents,
*etc

External events that must be addressed range from earthquakes to tsunamis to volcanic eruptions. Even aircraft crashes as seen in the video above are of potential concern.

Codes and standards have been developed by various national and international organizations, covering all areas of construction (materials, manufacturing, design), maintenance (inspection and testing), and quality assurance.<ref name=iaea/>
