Profile

Michael Ojovan joined the Department in 2002, having previously spent more than 20 years at The Moscow Scientific and Industrial Association "Radon", the leading radioactive waste research institution of Russian Federation. He is a Fellow of the Russian Academy of Natural Sciences and a Technical Expert of the International Atomic Energy Agency.

He is noted for his works on metal matrix immobilisation, powder metal fuels, self-sustaining vitrification, glass composite materials, the study of the long-term behaviour of cementitious, bituminous and glassy wasteforms, configuron percolation theory of glass transition and the viscosity of amorphous materials. He has published 340 peer-reviewed scientific papers, 19 IAEA documents, 42 patents and 12 books, including three editions of monograph "An introduction to nuclear waste immobilisation" by Elsevier (2005, 2014 and 2019).

Research interests

Main research activities:
Structure and properties of amorphous materials, Viscosity, Glass-liquid transition. Crystalline and Glassy materials for nuclear waste immobilisation, Corrosion and long term performance of glasses, Waste processing technologies. Vitrification, Cementitious wasteforms.

Earlier works:
