A Novel Marine Organism Trap for Important Plant Water Systems in Nuclear Power Plants

Abstract

As a safety-grade filtration device within the Important plant water systems of nuclear power stations, the marine organism trap bears the vital responsibility of ensuring reactor heat removal. Any blockage would trigger unit fault signals, leading to shutdown and loss of the safety-grade heat trap, with severe consequences. This paper introduces a novel multi-cartridge marine organism trap featuring planetary gear self-cleaning capability. It outlines the structure, operating principle, and design methodology, determining inlet/outlet pipe diameters, cartridge parameters, and filter area based on design specifications. This innovative filter offers reference for selecting and designing filters within Important plant water systems for nuclear power plants.
