Lecture 1

Topic: Vitreous materials for nuclear wasteimmobilization

Lecturer: Prof. Michael Ojovan

Biography: Michael Ojovan has been Nuclear Engineer of International Atomic Energy Agency (lAEA), and Professor of lmperial College London, UK, Tohoku University, Japan and Wuhan University of Technology, China. He is the Chief Editor of Wiley journal "Science and Technology of NuclealInstallations". He is known for the connectivity-percolation theory (CPT) of glass transition, Douglas-Doremus-Ojovan (DDO) model of viscosity of glasses and melts, theoretical bases of condensed Rydberg matter (RM), metallic and glass-composite materials for nuclear waste immobilization. He has published more than 200 scientific articles and 17 books including the "Handbook of Advanced Radioactiveand Waste Conditioning lechnologies" and the 3rd editions of "An Introduction to Nuclcar Waste lmmobilization" by Esevier.

Lecture 2

Topic: Tellurite glasses to immobilize volatile iodine from pyrochemica reprocessing of spent nuclearfuels

Lecturer: Prof. Jong Heo

Biography: Jong Heo has been Professor of Pohang University of Science and Technology (POSTECH), South Korea and Wuhan University of Technology, China. He was an associate editor of Journal of the American Ceramic Society and the head of the department of MSE in POSTECH. His research interests include glasses containing semiconductor quantum dots, advanced glasses for white LED, glasses for nuclear waste disposal, etc. He has published more than 200 scientific articles and 30 patents.

Lecture 3

Topic: Rheology of complex silicates: Magmas and nuclear waste glasses

Lecturer: Dr. Luiz Pereira

Biography: Luiz Pereira is currently working at Beihang University (Hangzhou, China). He earned his PhD from MINES ParisTech and CEA in France. After his Ph. D, he was awarded an Alexander von Humboldt fellowship and conducted research at Ludwig-Maximilians-Universität (LMU) München (Germany). His research focuses on understanding the behavior of molten silicates containing bubbles, crystals, and droplets in both natural and industrial contexts. He has published more than 20 scientific articles in internationally recognized journals, received five scientific awards, and was invited to present seven keynote lectures in international conferences.

Lecture 4

Topic: A brief introduction and outlook on future colaborationin nuclear gasses simuation

Lecturer: Dr. Zhang Qiang

Biography: Dr. Zhang Qiang obtained his Ph.D. from the Karlsruhe Institute of Technology (KIT), Germany, in 2021. From 2021 to 2024, he conducted postdoctoral and visiting scholar research at the Hereon Institute, Helmholtz Research Center, in Germany. Since 2025, he has been working at China National Nuclear Engineering Corporation. His research focuses on materials-related computational modeling. This includes the screening of functionalized metal-organic framework (MOFs) materials, predicting their properties, and simulating their self-assembly processes. He also studies polymer degradation and diffusion behavior. In addition, he works on computational modeling of nuclear waste glass solidification. He has published numerous research papers in internationally renowned journals such as Nat. Com. and Angew.
