Abstract

The invention relates to a risk assessment method of an earthquake and external flooding for a nuclear power plant. The method comprises the following steps: S100, carrying out a nuclear power plant earthquake response analysis and quantification; S200, carrying out an analysis of frequency of occurrence of external flooding caused by nuclear power plant site earthquake; S300, carrying out a response analysis and quantification on a situation of an earthquake with external flooding; and S400, calculating an earthquake-external flooding risk at the nuclear power plant. According to the invention, on the basis of an earthquake probability safety evaluation method and an external flooding probability safety evaluation method, the occurrence frequency of the earthquake damage state accident sequence with external flooding is obtained based on quantification and thus correlation between the earthquake and external flooding can be treated well, thereby guaranteeing accuracy of the analytical method and result.

Description

technical field [0001] The invention relates to nuclear power plant risk assessment technology, more specifically, relates to a nuclear power plant earthquake superposition external water flooding risk assessment method. Background technique [0002] Nuclear power plant probabilistic risk assessment technology has been developed since the 1970s. For single internal and external disasters including earthquakes and external flooding, relatively mature guidelines and standards have been formed, such as ASME / ANS Ra- Sa-2009, ERPI TR-1002989, etc. For single external disasters such as earthquakes and external flooding that have an overall impact on nuclear power plants, the risk assessment process is generally divided into three parts: risk analysis, vulnerability evaluation, and system analysis (response analysis). [0003] Before the Fukushima nuclear accident, the risk assessment of superimposed external disasters of nuclear power plants did not attract enough attention, and ...
