Abstract

The Nuclear Waste Management Organization (NWMO) has proposed the concept of an engineered barrier system for the disposal of Canada’s used nuclear fuel.  A major component is the used fuel container consisting of a steel structural core coated with copper for corrosion protection.  The NMWO is currently pursuing a program to characterize the copper coatings for performance evaluation.  Electron backscattered diffraction was performed on electrodeposited copper and reference wrought copper to characterize and compare their microstructures based on grain size/shape, grain size distribution, texture, and grain boundary character distribution. Focused ion beam microscopy was also performed on electrodeposited copper.
