Nuclear power plant earthquake early warning and monitoring system and method

Abstract

The invention discloses a nuclear power plant earthquake early warning and monitoring system and method. The system comprises an earthquake early warning system used for sending earthquake early warning before an earthquake reaches a nuclear power plant and an earthquake monitoring system used for reflecting the actual influence of earthquake motion on the structure and equipment of the nuclear power plant. The earthquake early warning system comprises: an early warning information receiving module used for receiving earthquake early warning information sent by an earthquake station network center; an early warning information sending module which is used for sending the earthquake early warning information reaching the fortified earthquake intensity to the main control room earthquake early warning module; and a master control room earthquake early warning module which is used for sending an earthquake early warning sound-light alarm in the master control room. Compared with the priorart, the earthquake early warning and monitoring system for the nuclear power plant can effectively fuse earthquake early warning information and earthquake monitoring information of the nuclear power plant together, and the two systems are independent of each other and proof each other, so that early warning is provided for possible earthquakes, and meaningless shutdown operation is avoided.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant earthquake monitoring, and more specifically, the invention relates to a nuclear power plant earthquake early warning and monitoring system and method. Background technique [0002] According to the requirements of National Nuclear Power Plant's Seismic Design and Appraisal (HAD102-02), my country's nuclear power plants under construction and in service are equipped with a Seismic Instrument Monitoring System (KIS), which is used to monitor earthquake information in real time, issue earthquake alarms and measure 1. Store seismic data so that the necessity of inspecting nuclear power plant shutdown after an earthquake can be assessed, and at the same time, collect dynamic behaviors of structures, systems and components of nuclear power plants to evaluate analysis for seismic design and appraisal of buildings and equipment Applicability of the method. [0003] However, the earthquake moni...

Problems solved by technology

[0003] However, the earthquake monitoring system can only send out an alarm and record the vibration information when the earthquake has affected the nuclear power plant area, but cannot realize the "early warning" function. Responding in a hurry, but unable to prepare in advance
