The quality of Probabilistic Safety Assessments (PSA), frequently named as probabilistic risk assessment (PRA), is one of the core issues in advanced nuclear power plant applications. Although numerous guidance and regulations have been provided to enhance the PSA quality, the inherent uncertainty of current PSA and project management process still make it to be puzzled. Based on the implementation of current PSA development status and limitation, a new integral model accounting for interrelated economic, health, security, quality, environmental and economic matters as well as quality attributes is proposed in this article. We aim to provide a new idea for other investigators and hope it can be help to further enhance the quality of PSA in industrial applications.
