Nuclear power plant earthquake response early warning device and its construction method

Abstract

The invention provides a nuclear power plant earthquake response early warning device and a building method therefor. The nuclear power plant earthquake response early warning device comprises an earthquake instrument monitoring system which is arranged in a nuclear power plant and used for inputting earthquake intensity and frequency data, earthquake risk interval data and weight data to an earthquake motion risk data table to generate an earthquake motion risk database, and a list output module which is used for outputting a list of primary risk equipment and buildings with shock resistance lower than the earthquake intensity according to the earthquake intensity and frequency data in the earthquake motion risk database and shock resistance mid-value data in a vulnerability degree database. The nuclear power plant earthquake response early warning device and the building method therefor have the advantages of ingenious technique and high practicality.

Description

technical field [0001] The invention relates to the field of nuclear power plants, in particular to an earthquake response early warning device for nuclear power plants and a construction method thereof. Background technique [0002] Earthquakes pose a very significant safety threat to nuclear power plants; the current seismic capacity of nuclear power plants is designed to resist design basis earthquakes (that is, safe shutdown earthquake SSE, ground motion acceleration of 0.2g); the design, analysis, and calculation of this seismic capacity There is a certain amount of seismic margin in different stages of construction. However, earthquakes are difficult to predict, and the possibility exists that larger earthquakes will occur. Moreover, even within the scope of the safety shutdown earthquake (the magnitude does not exceed the safety shutdown earthquake), the earthquake may still pose a threat to the safety of the nuclear power plant. [0003] At present, nuclear power p...

Problems solved by technology

[0004] The present invention is aimed at the existing seismic instrument monitoring technology of nuclear power plants, which can only monitor the earthquake, and cannot predict the failure of the equipment in the event of an earthquake, nor can it give action instructions to the operating personnel; at the same time, the existing earthquake response action requirements are too broad, targeted and The guidance is not strong, and it is difficult to ensure that the inspection of key equipment is completed within the required time. A nuclear power plant earthquake response early warning device and its construction method are proposed
