Abstract

The aim of this study was to perform a thermal–hydraulic analysis of SCWR cooled by nanofluids at various volume fractions (2%, 6% and 10%) of Al₂O₃ nanofluid. The temperature distribution of fuel, cladding surface and coolant in axial direction are investigated. The achieved results show that density, viscosity, thermal conductivity of the coolant increases with the increase of Nano particles volume fraction. Contrasting to specific heat, which decreases with the increase in nano particles volume fraction. For 10% volume percentage of nanoparticles the coolant temperature difference with pure water is about  24.2 °C , 62.5 °C and 94°C  at constant pressure 25, 30, and 35 (MPa) respectivly. Using nanofluids with 10% volume percentage of nanoparticles as coolant has significant effect on fuel temperature that the maximum fuel temperature reduced by 26.5%, 25% and 21% at constant pressure 25, 30, and 35 (MPa) respectivly.
