Max Fang has been with the group for a year as a visiting graduate student, and during this time has mostly been working on modelling the kinetics of copper corrosion. Max's work has given us new insights into copper corrosion kinetics, allowing us to refine our reaction mechanisms and predictive capabilities. He has also also made great efforts over the last few months to improve the general modelling skills of the group. Thanks for all your hard work! Max, we'll miss you, and we wish you the best of luck in finishing your Phd and whatever you decide to do afterwards.
Congratulations to our PhD candidate Ryan Morco who is the recicipient of a 2017 Roy G. Post Foundation Scholarship. The Roy G. Post Foundation is a non-profit organization that provides scholarships to students to develop careers in the safe management of nuclear materials and to participate in the WM Conference.
Ryan’s research is to assess the influence of gamma-radiation on the proposed used fuel container’s materials, and particularly that of copper corrosion under the different deep geologic repository (DGR) conditions. He is developing a chemical kinetics model on the radiolysis of humid air, pure water and saline groundwater which are conditions anticipated in a nuclear waste DGR environments. These models predict radiolytic oxidants and their concentrations which are then tested for corrosivity and compared with a radiation exposure experiments.
The R.E. Jervis Award is provided by the Canadian Nuclear Society (CNS) and recognizes excellence in research and development carried out by a full time graduate student in nuclear engineering or related fields. It is awarded once a year. Congratulations to our PhD candidate Mojtaba Momeni for winning this prestigious prize.
Mojtaba's research is in the area of corrosion of Cr-Fe-Ni alloys in nuclear reactor environments. His research on enhancing the understanding and modelling of corrosion kinetics and how water chemistry induced by gamma radiation may affect corrosion kinetics has already produced significant outcomes valuable to the Canadian nuclear industry.

Belated congratulations to Arielle on the successful defense of her MSc. thesis "Evolution of Cu2O Morphology During Copper Corrosion in the Presence of Gamma-Radiation" Well done! Details on Arielle's thesis can be found here:
Congratulations to our PhD candidate Mi Li for winning the award for the best oral presentation at the NACE southern Ontario student section.
Mi is studying the effect of γ-radiation on the corrosion of carbon steel (CS, SA36) - stainless steel (SS, Type 304L) welds under different pH and temperature conditions. These types of welds are used in CANDU nuclear reactors in regions that are exposed to water under a constant flux of γ-radiation. When exposed to ionizing radiation, water decomposes into some highly redox-active species which might affect the corrosion behaviour of metals. These factors, as well as possible changes in the temperature, can affect the rate of corrosion.
