System and method for monitoring risks of nuclear power plant based on cloud architecture

Abstract

The invention discloses a system and a method for monitoring risks of a nuclear power plant based on a cloud architecture. The system comprises eight functional modules. The system is built based on a cloud platform, and builds idle physical machines in the nuclear power plant into a virtual machine cluster through the Internet, the system can perform the automatic migration of fault nodes so as to ensure the stable, reliable and continuous running of the nodes; and by using the advantages of the combination of cloud computing and distributed computing, a problem that when a maintenance plan management module of the system for monitoring risks is used to carry out a large-scale maintenance plan, computing resources are dynamically distributed according to the number of state points of the maintenance plan, thereby solving the problem that too slow computing speed can not meet the demands of practical production management and saving the computing resources to the greatest extent.

Description

technical field [0001] The invention relates to a system and monitoring method for nuclear power plant risk monitoring and management based on cloud architecture design, which belongs to the technical field of safe operation and management of nuclear power plants, and the technology can also be applied to reliability analysis and monitoring in the fields of aviation, aerospace, and chemical industry . Background technique [0002] Nuclear safety is the lifeline of nuclear power development, and the risk monitor is a nuclear safety analysis and risk management software system that assesses real-time risk levels based on the actual configuration status of nuclear power plants. The risk monitor not only makes the qualitative estimation of the risk level of nuclear power plants based on operating experience become history, but also can balance the contradiction between the operating safety and economic benefits of nuclear power plants. [0003] At any point in time, the risk mo...

Problems solved by technology

In addition, in the existing risk monitoring system, there may be situations where multiple users use the system for calculation at the same time and a single user performs large-scale maintenance plan calculation, which will cause the following problems: (1) Users may need to wait for a long time during the calculation process of the system Calculation results; (2) Uncertainty in the number of system users and usage methods lead to high scalability requirements for network applications, and if the system structure design is inflexible, if the number of collaborative users is large or the maintenance plan is large, the server load The pressure is very high, which may cause the system to crash; (3) The number of concurrent users and status points of the maintenance plan is uncertain, and the number of computing resources required is uncertain; (4) Once the server fails, users cannot use the system for risk Management, calculation and query, resulting in low system reliability
