Description

technical field

[0001] The invention relates to the implementation field of the Severe Accident Management Guidelines (SAMG) of a pressurized water reactor nuclear power plant, and mainly relates to a method for diagnosing and treating a serious accident of a pressurized water reactor nuclear power plant. Background technique

[0002] As we all know, the events and accidents of PWR nuclear power plants can be divided into two categories: The first category is the normal operating conditions defined by the emergency shutdown of the reactor. Specifically, for such accident conditions, the technical specifications require that the plant be able to reach a certain fallback mode, where some equipment is not available due to failure. For such events and accidents, the priority is the integrity of the safety barrier, which ensures the integrity of the core and prevents core damage. The second category is severe accidents, in which a significant deterioration of the core performanc...
