Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

This paper performs a detailed analysis of the optimized Ontario power mix under impending load and emissions constraints with the consideration of small modular reactor (SMR) deployment. The target of minimizing the total cost of the 2055 power mix while retaining real-world energy requirements was achieved using a semidynamic, recursive linear optimization model with hourly time resolution for the accurate consideration of wind and photovoltaic variable renewable energy. Utilizing IBM’s ILOG CPLEX Optimization Studio’s Flow Control method, dynamic factors such as forecasted demand growth, increasing capacity installations, learning curve applications, and reactor refurbishment and decommissioning schedules were applied to the modeling scenarios. Optimized scenarios have demonstrated that SMR-based capacity should play a vital role in the provincial energy mix in order to minimize cost while meeting emissions reduction goals and responding to increasing demand. Simulations show ideal cost reductions when approximately one-third of generated energy is produced by SMRs in the future energy mix and that the absence of SMRs may lead to up to 29% higher spending. Additional cases have considered the benefits of early SMR investment and direct SMR-CANDU cost comparisons.
