Technical Study For Marine Biomonitoring Based On Multi-source Eterogeneous Data At Nuclear Power Plant Intake Channels

Due to its friendly contribution to the environment,nuclear power has become a priority for human energy development.However,due to significant changes in the marine ecological environment due to human activities and other factors in recent years,many marine algae and other plankton,jellyfish and shrimp Outbreak of the incident.According to a report by the World Association of Nuclear Operators(WANO)on the cold water intakes of nuclear power plants,it has been shown that more than 80% of the biohazard clogging in the intake sea affects the unit power generation and has a direct impact on safety-related systems of 20% %.Nuclear power plant response to marine outbreaks weak capacity,the lack of necessary means of detection and warning technology is one of the key factors.In this paper,the automatic monitoring technology system for establishing marine intakes of nuclear power station intake by using information processing is the ultimate goal to improve the ability of cold source to deal with sea creatures intrusion detection.Based on the biological characteristics analysis of typical invasion seawater from cold source of nuclear power plant,,Hydrodynamics and other detection technologies;re-constructing the ontology model to establish a quantitative assessment algorithm for the tendency of marine invaders;and constructing an online monitoring system to verify the multi-source heterogeneous marine biometric assessment model.This study is combined with the actual needs of current applications and has the following theoretical and technological innovations:1.Proposed multi-source heterogeneous technology route for biological monitoring of water intakes in nuclear power plants,and provided ontology extraction and ontology reconstruction methods;2.Based on the researches on the assessment of marine biological resources both at home and abroad,this paper proposes a multi-source heterogeneity monitoring model of biological acoustic at the inlet of a nuclear power plant,a composite monitoring model of acousto-optic marine life,and a marine biological monitoring model including space-time domain;3.Design and establish on-line monitoring system for water intakes of nuclear power stations,and realize and verify the multi-source isomorphism online monitoring model.
