摘要：

To update PSA (probabilistic safety assessment) model this paper presents a computer based living probabilistic safety assessment (LPSA) method named as online risk monitor system (ORMS). The essential features and functions of ORMS have been described in this research. A case study of emergency diesel generator (EDG) of Daya Bay nuclear power plant (NPP) has been done; operational failure rate and demand failure probability of EDG has been calculated with the help of ORMS. The results of ORMS are well matched with data obtained from Daya Bay NPP. ORMS is capable of automatically update the online risk models and reliability parameters of equipment in time. ORMS can support in decision making process of operator and manager in nuclear power plant. (C) 2013 Elsevier B.V. All rights reserved.
