On the use of the Balancing Method for calculating component RAW involving CCFs in SSC categorization

In this paper, it is revived and suggested that the method called ‘Balancing Method’ could be used in deriving a component risk achievement worth (RAW) from the basic event RAWs including common cause failure RAW, and the Balancing Method is compared with the other methods. Since the component RAW value generated by the Balancing Method very closely resembles the real component RAW value, the Balancing Method could be widely used in the calculation of the component RAW which plays a key role in the risk informed regulation and applications.
