A simplified CREAM prospective quantification process and its application

Cognitive reliability and error analysis method (CREAM), with a sound cognitive model and framework with an emphasis of the whole characteristics of context, is a representative method of the so-called second generation human reliability analysis (HRA) methods and can be used in both retrospective and prospective analysis. For prospective analysis in the context of PSA/HRA, the need of CREAM to provide the results in quantitative terms is seemingly unavoidable. One remaining problem of CREAM as HRA is how to provide an easily practicable process to get the numeric results. This paper provides a simplified CREAM prospective quantification process including the basic method and extended method and their applications in the SGTR event of Qinshan 1 NPP. A comparison is made between the CREAM and THERP in the quantification and a data collection system is proposed to provide a more validated data source for future application of CREAM method.
