Nicolas Reynier, PhD

Research Scientist

Actinide Hydrometallurgy

Natural Resources Canada

Current research and/or projects

Biography:

After completion of my Chemistry degrees in France and a work experience in actinide separation for military nuclear applications, I completed a PhD at the INRS, Québec on contaminated soil remediation. I am working at CanmetMINING on nuclear & mine wastes reprocessing for metals recovery. I am developing innovative process to improve valuable metals recycling, decrease environmental liabilities of radioactive wastes & avoid proliferation of fissile materials in Canada.
