Abstract

The invention discloses a method and a system for diagnosing and responding and supporting a nuclear power plant severe accident. The method comprises steps of obtaining accurate information needed by accident management by combining an instrument usability database through accident-correlated-instrument monitoring and correlated important parameter evolvement, realizing simulation of server accident development and an emergency state through the combination of a sever accident simulation module, predicting the development tendency of the server accident and predicting expected effects after various possible intervention measurements, integrating and electronizing the server accident management guidance (SAMG) and giving advices on the following measurements. The invention can start up the corresponding measurement and the emergency plan on the short notice, maximally reduces the accident risk, provides the guarantee and further enhances the safety of the nuclear power plant.

Description

technical field [0001] The invention relates to the implementation of the Severe Accident Management Guidelines (SAMG) of nuclear power plants and the field of nuclear power plant emergency auxiliary decision-making, in particular to a method and system for severe accident diagnosis and response support of nuclear power plants. Background technique [0002] The Severe Accident Management Guidelines (SAMG) of nuclear power plants is an executable document used in the main control room and technical support center under severe accidents. It is a relatively complete and integrated guidance for handling severe accidents Manage files. SAMG is a set of countermeasures for possible severe accidents in nuclear power plants based on the existing systems and equipment of nuclear power plants. It is a major improvement in the management of severe accident mitigation capabilities. However, due to the When a serious accident occurs in the factory, the monitoring instrument is damaged, o...
