Lire la suite >In the frame of severe accident topic for pressurized water reactor, the physical-chemistry of Ru fission products were experimentally studied to better understand their behavior inside the reactor coolant system in air or air/steam atmospheres. The tests consisted in vaporizing RuO2 at 1200 °C and the ruthenium oxides are transported through a controlled thermal gradient tube made of quartz or pre-oxidized stainless steel. Results show that the major part up to 95% is deposited along the tube, the remaining part being transported almost under gaseous form attributed to RuO4. Impact of carrier gas, temperature profile and nature of the tube are discussed.Lire moins >
