The water intake sewage interception facilities are the important component of the cold source safety measures for nuclear power plants. To ensure the structural safety of the water intake sewage interception facilities in a nuclear power plant, a physical model test of the interception facilities in a certain nuclear power plant's water intake channel is conducted to study the force changes of pile foundation piers and main cables of the interception net under different combinations of waves, plugging rates, and elongation rates of the interception net, as well as the influence of different Enteromorpha weights and stacking forms on the force of the main cables. The experimental research results can provide input parameters and scientific basis for the structural design of sewage interception facilities and the operation and maintenance of nuclear power plants, ensuring the safety of cold source in nuclear power plants.
