Neutronic and Thermalhydraulic Evaluation of Annular Fuel in PWR with Three Different Nanofluids
In pressurized nuclear reactors, one of the fuel design principles is the fuel centerline temperature limit. Since the thermal conductivity of UO2 is not high, the temperature increases rapidly from the fuel surface to the fuel center.

Influence of oxide films on primary water stress corrosion cracking initiation of alloy 600 [PDF]
In the present study alloy 600 was tested in simulated pressurised water reactor (PWR) primary water, at 360 °C, under an hydrogen partial pressure of 30 kPa. These testing conditions correspond to the maximum sensitivity of alloy 600 to crack initiation.
