The project is led by Dr. Kristen R.... MoreWednesday, August 24, 2022Addressing nuclear power’s social challenges to increase deploymentNuclear power could provide large amounts of low-carbon electricity that would help us deeply decarbonize the global energy system. However, it often faces societal challenges that dampen its deployment prospects. What are these challenges and how do we resolve them in the next generation of reactors? As part of his work on the U.S.... MoreThursday, May 26, 2022PhD position in the modelling of separation processes and negative emissions technologiesA PhD position in the modelling of separation processes and negative emissions technologies is open in the Alternative Pathways for the Energy Transition (APEX) laboratory at Carleton University.
