Fukushima Daiichi accident shows that extreme external events may lead to extensive damage in nuclear power plants (NPPs), which may not only affects equipment, but also damage the control and monitor ability of control rooms (including human factor, habitability, control panel and so on). Accidents-related procedures of NPPs in China are Emergency Operation Procedures (EOPs) and Severe Accident Management Guidelines (SAMGs), both of them rely on control and monitor ability of control rooms. Therefore, current structure of accident management procedures can’t work effectively in the scene of extensive damage. The development of Extensive Damage Mitigation Guidance (EDMGs) may strengthen the defense in depth. In relation to this, an Integrated EDMG has been developed to deal with extensive damage resulted from fire (or explosion) or extreme hazards, while the Nuclear Energy Institute (NEI) EDMG only considers fire and explosion. Besides the extended scope, Integrated EDMG develops a comprehensive and detailed mitigation method which is applicable for extensive damage. In this paper, the characteristics of extensive damage will be analyzed first, and then the structure of Integrated EDMG is developed based on the characteristic analysis. According to the emergency response analysis and accident management research, detailed introduction of the Integrated EDMG and its sub-guidances are discussed.
