Description

Technical Field

[0001] This utility model relates to the field of marine organism removal technology for cold sources in nuclear power plants, and in particular to a device for intercepting, filtering and removing marine organisms from cold sources in nuclear power plants. Background Technology

[0002] The marine organism interception scheme for the cold source of a nuclear power plant involves using equipment such as oil booms, alloy interception nets, fine-mesh interception nets, and herringbone-patterned debris nets to intercept marine organisms. Multiple nets are typically installed along the water intake path. Theoretically, after the second net, marine organisms larger than 5mm in diameter can be intercepted. However, due to the influence of high and low tide levels and the flexible nature of the nets, debris and marine organisms larger than 5mm often accumulate at the end of the nets, along with the accumulation of tiny marine organisms. In such cases, manual retrieval of the net ends is necessary, which is inefficient and carries operational risks. Utility Model Content
