The liquid metal cooled fast reactor has been recognized as a prominent candidate in the fourth generation of advanced nuclear energy systems, largely due to its high inherent safety and economic viability. However, the corrosive nature of liquid lead–bismuth alloy can lead to the formation of insoluble corrosion particles during pipe erosion, which may enter the reactor core and deposit in narrow flow channels, such as wire-wrapped rod bundles, posing a risk to the safe operation of lead–bismuth fast reactors. This study employs numerical methods integrated with the Discrete Phase Model (DPM) to investigate the deposition characteristics of insoluble corrosion products in a single wire-wrapped channel within a lead–bismuth environment. The analysis explores the effects of wire wrapping, flow field dynamics, inlet parameters, and particle characteristics on the migration and deposition behaviors. Our findings indicate that particle deposition predominantly occurs near the inlet region and the trailing edge of the wire rotation. Moreover, particles exceeding 20 μm significantly alter sedimentation characteristics. Inlet velocity and particle diameter emerge as critical factors influencing deposition rates, with particle diameter being the dominant factor for sizes greater than 20 μm, while inlet velocity plays a more significant role for smaller particles, especially at velocities below 2 m/s. These insights contribute valuable knowledge for the safety design and operational integrity of lead–bismuth fast reactors.
