Monitoring and early-warning method and system for reactor

Abstract

The invention provides a monitoring and early-warning method and system for a reactor. The method comprises the following steps: S1, constructing a reactor core model and rebuilding a reactor core graph according to the reactor core model; S2, acquiring the first data file of a three-dimensional fuel assembly, constructing the first reactor core numerical model of the reactor according to the first data file, and monitoring the reactor in real time by using the first reactor core numerical model; and S3, acquiring the second data file of the three-dimensional fuel assembly, constructing the second reactor core numerical model of the reactor according to the second data file, and carrying out early warning of the reactor by using the second reactor core numerical model. The monitoring and early-warning method and system provided by the invention can improve the on-line monitoring and early warning precision of the reactor, simplify the modeling process of the reactor, reduce artificialerror rates and improve the reliability of monitoring and early warning of the reactor.

Description

technical field [0001] The invention relates to the technical field of reactor operation support, in particular to a reactor monitoring and early warning method and system. Background technique [0002] The safe operation of the reactor is the main concern of nuclear power operation engineers and power plants. By installing the reactor monitoring and early warning system in the main control room, the power plant can realize real-time monitoring of the reactor status and provide guarantee for the safe operation of the reactor. [0003] The main functions of the current reactor monitoring and early warning system include: using the real-time measurement information of the reactor, online calculation of the important safety parameters of the reactor and displaying it on the human-computer interface for the operator's reference; virtual operation of the reactor in a certain operation mode, Provides the expected future state of the reactor; periodically (usually once a month) dra...

Problems solved by technology

This tracking mode discards part of the information of the fuel assembly (especially the three-dimensional assembly information). At the same time, the discarded information will also lead to the deviation of the system when numerically simulating the reactor, which indirectly leads to the deviation of the real-time monitoring accuracy of the reactor, which leads to the monitoring accuracy not tall
