title = "PREDICTION OF PRESSURE DROP IN WIRE-WRAPPED FUEL ASSEMBLIES WITH BLOCKED CHANNELS USING LARGE EDDY SIMULATION",
abstract = "The thermal hydraulic behavior of wire-wrapped fuel assemblies continues to be a subject of intense research. One of the leading next-generation designs, the sodium fast reactor, relies on a hexagonal assembly of wire-wrapped fuel pins. Due to their tightly packed arrangement, the issue of potential channel blockage has been raised as a safety concern. This has lead to several recent experimental and computational studies working to quantify the potential impact on the fluid flow and heat transfer behavior of such blockages. The objective of this paper is to benchmark the high-fidelity NekRS CFD code in prediction of pressure drop for large blockages against available experimental data. A 61-pin assembly with a flow blockage configuration blocking 19.1% of the flow area has been investigated at various low to moderate Reynolds numbers. All simulated results agreed well the experimental data, indicating that the overall method is consistent.",
