| Abstract Scope |
Meeting growing energy demand and security have led to the acknowledgment of the importance of increasing nuclear energy efficiency, which requires nuclear materials can withstand increasingly extreme environments. Advanced nuclear reactors operator at higher temperatures and in more chemically aggressive environments, accelerating material degradation and posing major challenges for long-term performance. Addressing these issues demands a fundamental understanding of how materials behave under such conditions. Using examples from our research, I present strategies to overcome these challenges. Specifically, we integrate modeling with advanced experimental techniques to understand the relationship between microstructure/microchemistry, corrosion, and radiation responses in nuclear materials. In addition, I discuss strategies to design nuclear materials with enhanced corrosion resistant property, and how radiation couple with corrosion in materials. Altogether, these examples highlight the great potential of seamlessly integrating modeling and experiments into understanding and improvement of materials behavior in nuclear applications. |
