Abstract

Coastal nuclear power plants are facing the threat of plankton invasion. The large-scale outbreak of jellyfish in summer has had aserious impact on the safety of coastal nuclear power cold sources, seriously affecting the safe operation of coastal nuclear power. In addition to continuously strengthening interception and fishing measures, how to effectively detect and evaluate the quantity of marine biological resources such as jellyfish and provide real-time warning of marine biological invasion has become an important topic. This study focuses on early warning of jellyfish invasion and uses a scientific bathymeter (Simrad, Norway, EK60 model, 200kHz) to design and develop an acoustic monitoring system for cold source organisms (jellyfish). The echo integration method is used to measure and evaluate resource density, and real-time monitoring of cold source biological echoes in the sea area near the water intake is carried out to achieve the purpose of marine biological resource disaster warning. After processing acoustic data from July and August 2021 using Echoview software, the density of jellyfish resources was obtained. The monitoring results show that the maximum daily average value of SV is -52.7dB, and the minimum value is -72.3dB. According to the two month experimental monitoring results of the intake of the Hongyanhe Nuclear Power Plant, the system has good monitoring and warning functions and practical application prospects.
