Dr. Malcolm Griffiths has worked on various aspects of materials performance in nuclear reactor cores during his 32 years with AECL. He was instrumental in developing strategies supporting CANDU refurbishment addressing improving pressure tube performance and the degradation of Inconel X-750 components in CANDU reactors. From 2003-2013, he was on the editorial advisory board for the Journal of Nuclear Materials and was an editor from 2013-2016. In 2007, he was recipient of the Kroll medal from the American Society for Testing and Materials for his pioneering work on microstructure evolution in zirconium alloys during irradiation.While working at CRL, he was chair and project manager for the Candu Owners Group (COG) R&D program addressing Zr-2.5Nb pressure tube performance and the COG refurbishment joint project addressing Inconel X-750 spacer degradation. Since retiring in 2016, he is adjunct professor at Queens University and at Carleton University. He also consults through ANT International.
