The probabilistic risk assessment method does a poor job of anticipating accidents in which a single event, such as a tsunami, causes failures in multiple safety systems. Catastrophic nuclear ...

Probabilistic-risk-assessment techniques are necessary because black-box systems are inherently resistant to deterministic fault analysis, and complex accident sequences require systematic risk ...

Dynamic Probabilistic Risk Assessment: An evaluative framework that integrates system dynamics and probabilistic uncertainties to assess risks in environments where system states evolve over time.

"We have to know what's plausible," said retired Army Maj. Gen. Richard Engel, who headed a recent National Intelligence Council assessment of the national security risks posed by climate change.

At the CoE meetings, the experts and FAA leadership discuss areas such as human reliability analysis and training in probabilistic risk assessment and the use of risk assessments in continued ...

The Nuclear Regulatory Commission (NRC) should examine the benefits of mandating that nuclear plants in the U.S. add probabilistic risk assessment (PRA) to methods used to evaluate and prepare for ...

Probabilistic risk assessment models do not account for unexpected failure modes during many accidents. At Japan’s Kashiwazaki Kariwa reactors, for example, after the 2007 Chuetsu earthquake some ...
