Design Basis Accident

A Design Basis Accident (DBA) is a hypothetical, worst-case scenario used in engineering to ensure safety measures can effectively manage emergencies. It represents an accident that plants are designed to withstand without releasing harmful levels of radiation or causing significant harm to people or the environment. DBAs consider factors like equipment failure or natural disasters, providing a framework for safety protocols. By planning for these scenarios, facilities ensure they can remain safe and contain potential problems even under extreme conditions.
