Compound and Cascading Hazards — Industry Experience

Compound and cascading hazards — events where two or more external hazards affect a nuclear plant simultaneously, sequentially, or through causal linkage — present distinct challenges because their combined effects can differ qualitatively from those of any single hazard. Several notable events have shown that converging hazards can simultaneously challenge multiple safety functions, producing consequences that single-hazard analyses alone would not predict.
