RAMPS: What we do

We specialize in radiation and corrosion chemistry. We investigate the chemical mechanisms of the degradation of materials under radiation. In order to do this, we need to determine the concentrations and rates of production of the reactive compounds and radical species produced by radiation in various media, under a range of environmental conditions.  We are developing a more comprehensive and quantitative understanding of the influence of these "radiolysis products" on the behaviour of materials, and in particular the corrosion of metals. We also study applications of radiation chemistry in materials science (for example, nanoparticle formation).

We are currently looking for graduate students and postdoctoral fellows with strong chemistry backgrounds to join our group. If you are interested, fill in the contact form.

  • Rose Karimihaghighi, a PhD candidate in the Wren Group, has been awarded an OGS scholarship. 
  • Dr. Joseph gave a presentation at the 2018 Information Exchange Meeting on Super-Critical-Water-Cooled Reactors in Montreal. 
  • The Wren Group visited the Nuclear Waste Management Organization's Proof Test Facility for an information-exchange session.
  • In November, Dr. Wren attended the Corrosion Prediction and Mitigation for Key Components of Fukushima Daiichi NPS conference in Japan as an invited keynote speaker. Her lecture was entitled "Effects of Chemical and Physical Properties of Solution on Radiolysis Induced Corrosion of Carbon Steel".
  • Two of our PhD candidates, Dan Guo and Joseph Turnbull, have been awarded 2018 Roy G. Post scholarships. This scholarship was established to help students develop careers in the safe management of nuclear materials. For more information on their projects, see News.
