The first step in common cause failure analysis is the formation of common cause component groups. This group is formed based on dependencies between components. Once common cause component groups are formed, data collection is to be initiated for the common cause component groups under consideration...

for common-cause failure, and examples are illustrated using the alpha-factor parameterization, the approach adopted by the NRC in their Standardized Plant Analysis Risk (SPAR) models. The cases of a failed component (with and without shared common-cause failure potential) and a component being ...
摘要: A newly developed generalized expression for the mean time to failure of a k-out-of-n: G system composed of repairable units and subject to common-cause failures is presented. Also, reported are some special case system reliability and variance of time to failure formulas....
Common-cause failures (CCF) are simultaneous failures of multiple components within a system due to a common-cause or a shared root cause. CCF can contribute significantly to the overall system unreliability. Therefore, it is important to incorporate CCF into the system reliability analysis. Traditio...
Now that we understand WHAT Common-Cause Failure is and WHY it’s important, we can talk about HOW it is handled in ISO 13849-1. Since ISO 13849-1 is intended to be a simplified functional safety standard, CCF analysis is limited to a checklist in Annex F, Table F.1. Note that Anne...
In the second case, sensitivity analysis has been made in order to prioritize the important parameters which have largest contribution to system reliability and also for common cause failure analysis and uncertainty analysis. For an example of phased mission system, PWR containment spray system has ...
