Probabilistic Safety Assessment (PSA)

Published: Oct 12, 2018

Probabilistic Safety Assessment (PSA) is a reliability assessment method which analyses engineering or management systems where safety is critical. The technique is used to determine the reliability of a component, or system of components, based on the probability of a component or system failure. The technique is used extensively in the nuclear industry and usually forms a major part of Safety Cases. It is used less in the small user (non-nuclear) sector where more conventional Risk Assessments usually suffice.
