Reliability assessment under incomplete information: an evaluative study
Traditionally, in reliability design, the random variables acting on a system are assumed independent. This assumption is usually poor because in most real life problems the variables are correlated. The available information, most of the time, is limited to the first and second moments. Very few …

Advanced thermal hydraulic simulations for human reliability assessment of nuclear power plants
Human Risk Assessment (HRA) in the nuclear power industry has advanced in the last two decades. However, there is a lack of understanding of the magnitude of the effect of thermal hydraulic (TH) uncertainties upon the failure probabilities of the operator actions of nuclear units. I demonstrate in …
