As one of the most promising advanced reactors, the lead-based fast reactor has drawn great attention due to economic and safety advantages. Investigating thermal hydraulics is essential for the design of a lead-based reactor.In this paper, a CFD simulation of a 19-wire-wrapped-rod bundle with leadbismuth eutectic (LBE) as coolant is carried out using the Reynoldsaveraged Navier-Stokes equation method, and four different types of axial non-uniform heat flux are applied. Excellent validation of results for thermal and hydraulic aspects is obtained first by comparing simulation results using turbulent model k-ω SST with experimental data and high-fidelity large eddy simulation data. The mechanism of transverse flow variation in subchannels and faces resulting from changing locations of wires is studied.

“…Also, analysis codes for the advanced fast reactor are developed. 20,21 In general, the thermal-hydraulic characteristics and periodical distribution in fuel assemblies were explored. First, it was found that the axial velocity would periodically fluctuate because the wires sweep regularly, and the period was diverse in different sub-channel.…”
