Problems solved by technology

[0004] At present, the risk monitors of most power plants are not real real-time systems. Information such as equipment failure / out of service needs to be manually input by power plant personnel, and the existing electronic logs, data collection and processing database platforms of power plants are not fully utilized. Reliance on power plant personnel more sexual

Abstract

The invention discloses a nuclear plant safety evaluating system and method. Firstly, field data information of a power plant system / equipment is collected through a field information collecting device, and the collected field data information is processed; then the performance state of the power plant equipment is judged according to the processed field data information, and then the safety level of a power plant is evaluated according to the performance state of the power plant system / equipment and power plant system / equipment information recorded in a power plant system / equipment failure database. By means of the nuclear plant safety evaluating system and method, the safety level of the power plant can be evaluated in real time, the defect that a current risk monitor is more relied on personnel operation is overcome, safety of the power plant is ensured, and the availability ratio and the economical efficiency of the power plant are improved effectively.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant safety management, in particular to a safety assessment system and method for nuclear power plant safety and health management. Background technique [0002] Probabilistic Safety Assessment (PSA) is a risk quantitative assessment technology based on probability theory, and it is an effective tool for evaluating risks, understanding risks, and helping people manage and reduce risks. At present, through years of practice in the nuclear industry, PSA technology has been widely used in various fields such as design, operation and maintenance of nuclear power plants. PSA technology has played an important role in ensuring the safety and economy of nuclear power. Risk Monitor is a plant-specific real-time analysis tool used to determine the instantaneous risk based on the actual state of the system and components, and to provide dynamic risk information for nuclear power plants. [0003] In...
