Sadman Sakib

Graduate Research Assistant

Research Description

I am working towards my Ph.D. degree in Nuclear Engineering. My current research project proposes to enhance the scientific understanding of the mechanisms leading to high-burnup structure (HBS) formation in nuclear fuel and develop experimentally validated computational capabilities for predicting grain subdivision and associated fission products evolution. To improve the economics of commercial nuclear power production, utilities are seeking to increase the allowable burnup limit of UO2 fuel. However, exposure to extended burnup leads to the formation of a refined grain structure (i.e., HBS), which generates the risk of performance degradation and fragmentation of UO2 fuels. Therefore, understanding the HBS formation mechanisms and its impact on fuel performance is important.

Additionally, I will be working on:

• Analyzing effects of radiation on oxide nuclear fuels.
• Studying the change in the property of thermal transport due to irradiation induced defects on Uranium Oxide and Zirconium Oxide (UO2 Surrogate).

Background

I completed my BSc (Bachelors of Science) in Nuclear Science and Engineering from Military Institute of Science and Technology (MIST) which is a renowned engineering institution in Dhaka, Bangladesh. Throughout my undergraduate at MIST, I was research-wise, connected with building up a project and also my thesis and was successfully able to publish them at a reputed conference.
