Risk
The combined answer to three questions that consider (1) what can go wrong, (2) how likely it is to occur, and (3) what the consequences might be. These three questions allow the NRC to understand likely outcomes, sensitivities, areas of importance, system interactions, and areas of uncertainty, which can be used to identify risk-significant scenarios. For additional detail, see Risk Assessment in Regulation and the Fact Sheet on Nuclear Reactor Risk.
