Reactor Coolant Properties: liquid_sodium_SFR
Thermophysical properties of nuclear reactor coolants at operating temperatures and pressures. Covers light water (H2O) for PWR at 15.5 MPa (270-340°C) and BWR at 7 MPa (270-280°C), heavy water D2O for CANDU at 10 MPa (250-310°C), helium gas for HTGR/VHTR at 7 MPa (250-750°C), liquid sodium for SFR/LMFBR at near-atmospheric pressure (200-550°C), and molten salt FLiBe (2LiF-BeF2) for MSR (500-700°C). Properties: density, dynamic viscosity, thermal conductivity, specific heat, Prandtl number. Distinct from standard steam tables which do not cover D2O, sodium, helium, or FLiBe at reactor conditions.
