Distance Education

  • Zoom is the web conferencing tool for distance ed.
  • It is highly recommended that you review the Physics refresher / prerequisite material for this course and the general Math refresher / prerequisite to ensure you are ready for UN0804. See the Refresher / Prerequisite Material page for further information.


Although the level of physics and math required for UN0504 is relatively modest, it is highly recommended that you review the Physics refresher / prerequisite material for this course and the general Math refresher / prerequisite to ensure you are ready for UN0504. See the Refresher / Prerequisite Material page for further information.

Course Description

The course describes the role of the Small Modular Reactors (SMRs) in electricity generation and for special applications in developed and developing countries. Selected types of SMRs that are relevant and considered for implementation in Canada are described in the course.  The course covers the most important design features of selected SMR reactors in each group. The course summarizes the physics, thermalhydraulics, fuel and safety characteristics of the selected SMR designs. Comparison of safety improvements, inherent and passive safety features, and reactor safety margins for different SMR designs are included. 

Attendees must register in advance with Areti Tsiliganos (unene@mcmaster.ca). A reminder will be sent leading up to the dates for the courses.
