QRA uses logic models depicting combinations of events that could result in<br />

severe accidents and physical models depicting the progression of accidents<br />

and the transport of a hazardous material to the environment. The models are<br />

evaluated probabilistically to provide both qualitative and quantitative insights<br />

about the level of risk and to identify the design, site, or operational<br />

characteristics that are the most important to risk. QRA is distinguished from<br />

the qualitative approach by the analysis depth and integration of detailed<br />

assessments.<br />
