Education and training to support Canadian nuclear workforce development
Along with several other nations, Canada has committed to net-zero emissions by 2050. Part of this plan is tripling nuclear generating capacity. As of 2025, the country has four operating nuclear generating stations with a total of 17 reactors, 16 of which are in the province of Ontario. The Independent Electricity System Operator has recommended that an additional 17,800 MWe of nuclear power be added to Ontario’s grid.

Rigorous and consistent formulations of basic equations of interfacial area transport were derived using correlation functions of the characteristic function of each phase and velocities of each phase. The turbulent transport term of interfacial area concentration was consistently derived and related to the difference between the interfacial velocity and the averaged velocity of each phase. Constitutive equations of turbulent transport terms of interfacial area concentration were proposed for bubbly flow. New transport model and constitutive equations were developed for churn flow. These models and constitutive equations are validated by experimental data of radial distributions of the interfacial area concentration in bubbly flow and churn flow.
