Course Description

This is an introductory to intermediate level course, designed to provide a solid base of understanding of the synergy between plant chemistry and material corrosion/degradation. The focus is on CANDU systems, including the objectives of chemistry control, corrosion issues, and corrosion mitigation strategies. Relevant “real-life” examples will be provided along with short-form self-assessments and ample time for Q&A to ensure maximum material retention.

 

Course Outcomes

By the end this course, the participant shall gain:

• Knowledge of the mechanisms of the major forms of corrosion that affect nuclear plant materials;
• An understanding of chemistry control objectives for various CANDU systems;
• An appreciation for the relationship between the chemistry, design, and materials of construction in major CANDU plant systems
