PSA (Probabilistic Safety Assessment)

Probabilistic Safety Assessment (PSA) is a systematic method used to evaluate the safety of complex systems, like nuclear power plants. It estimates the likelihood of different accident scenarios and their potential consequences. By analyzing factors such as equipment reliability, human behavior, and potential failures, PSA helps identify risks and prioritize safety improvements. This approach allows organizations to better understand how to prevent accidents and enhance safety measures, ensuring that systems remain robust and protective against unforeseen events.
