Heat transfer study of nanofluids as coolant in SCWRs core has been performed at Helwan University. A thermal hydraulic code has been produced to study the effect of TiO2 nanofluid water based as a coolant with comparison with pure water as a coolant. Various volume fractions of nanoparticles TiO2 (2%, 6% and 10%) were used in order to investigate its effects on reactor thermal–hydraulic characteristics. Based on Parameters of a SCW Canadian Deuterium Uranium nuclear reactor (CANDU), the fuel assembly was modeled to study the effect of nanoparticles volume fraction on thermos-physical properties of basic fluid and the temperature distribution of fuel, cladding surface and coolant in axial direction. The theoretical results showed that the density, viscosity and thermal conductivity of the coolant increases with the increase of nanoparticles volume fraction. Contrasting to specific heat, which decreases with the increase in nanoparticles volume fraction. Thermal conductivity increases with 2%, 6% and 10% volume fraction of nanoparticles by 5.5 %, 18.1%, 32.1% respectivly, at constant pressure 25 (MPa). 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. On the other hand, using nanofluid with 10% volume percentage of nanoparticles as coolant has significant effect on fuel temperature that the maximum fuel temperature reduced by 26.2%, 23.8% and 18.9% at constant pressure 25, 30, and 35 (MPa) respectivly.
