Abstract

Aiming at the problem that marine organisms entering the water intake threaten the safety of cold source system, a fixed-point acoustic monitoring method for marine organisms in the open water intake channel of nuclear power plant is designed. Ek80 scientific fish detector is used to monitor all kinds of cold source organisms, so as to obtain the density change of juvenile fish and other marine organisms in the open water intake channel in front of the open net interception network, and the efficiency of collecting marine organisms by the open net interception network; The designed acoustic fixed-point monitoring is in front of the first mesh interception network in the seawater open channel, and the beam direction is vertical downward. The monitoring results show that under normal sea conditions: floating marine organisms will enter the interception network through acoustic beam; the larvae of swimming fish with certain swimming ability rarely enter the interception network.
