A research project on the impact of CCF treatment in PSA and PSA application calculations, and especially during calculation of the risk achievement and risk decrease importance measures was performed in 2005 for SKI, the Swedish Nuclear Power Inspectorate. SKI project 14.2-041049/200402008.
CCFs are dominating contributors to risk. It is therefore important with both development and correct use of CCF data. It is also important to treat CCFs in a correct and realistic manner in the calculations of the core damage frequency and when quantifying importance and sensitivity for CCF-related events, both in the basic PSA and in PSA applications....
