There are various modeling techniques which are used in almost every field of science and engineering to estimate different entities on a set of parameters. These estimations contain uncertainty and imprecision due to non-ideal behavior of input data used in the modeling techniques. In risk assessment, reliability models are used in Probabilistic Safety Assessment (PSA). These models are usually based...
The most lethal role of Common Cause Failures (CCFs), which motivate the experts to investigate it, is the dependent behavior therein contained, which leads to simultaneous failure of the systems. Highly redundant systems are more susceptible to be affected by CCFs and also CCFs have been recognized as the principal contributor in the terrestrial reactor accidents. In the past, plenty of work has...
Nuclear accidents and incidents such as Three Mile Island (TMI-2) accident (1979), Chernobyl disaster (1986) and the recent Fukushima nuclear disaster (2011) have caused people to be suspicious of the safety of nuclear energy, and have reduced the level of trust among public. Common cause failure (CCF) has been a major element of such accidents in terrestrial nuclear power reactors because of high...
