Youyeon Choi: Innovating Small Modular Reactors
Youyeon Choi’s fascination with geometry began in high school, where she found clarity in shapes and dimensions. Now, as a doctoral candidate under Professor Koroush Shirvan at MIT, she integrates her passion into groundbreaking research on small modular reactors (SMRs). Her thesis centers around a unique helical cruciform-shaped metallic nuclear fuel, which optimizes performance by enhancing surface area and reducing heat flux, far surpassing traditional cylindrical fuel.
Having grown up in South Korea—home to a robust nuclear energy infrastructure supporting nearly a third of its electricity—Choi became acutely aware of the critical importance of nuclear technology. Her academic journey took her from an initial interest in nuclear fusion to a specialization in fission at Seoul National University, where she earned both her bachelor’s and master’s degrees in nuclear engineering.
Choi’s role at the Korea Atomic Energy Research Institute involved developing passive safety systems and nuclear security protocols, equipping her with invaluable experience in a field noted for its global impact. However, a yearning for technical modeling led her to MIT, drawn by its esteemed nuclear engineering program.
At MIT, Choi is dedicated to enhancing SMR efficiency, addressing the challenges of cost and electricity generation. Her innovative research utilizes advanced multi-physics modeling techniques, focusing on reactor physics and thermal hydraulics. With support from Lightbridge Corp. and the U.S. Department of Energy, her work promises a promising future for nuclear energy sustainability.
Rethinking Energy: The Future of Small Modular Reactors
The evolution of small modular reactors (SMRs), propelled by researchers like Youyeon Choi, holds profound implications for society and the global economy. As nations grapple with climate change and diminishing fossil fuel reserves, SMRs offer a transformative path toward cleaner energy. Their ability to deliver cost-effective, scalable power solutions aligns with the urgent need for reliable energy sources, especially in developing economies where access to electricity can be a matter of progress.
The societal acceptance of nuclear energy, historically marred by safety fears, is undergoing a renaissance as technological advancements—like Choi’s innovative helical fuel design—promise enhanced safety and efficiency. Public perception is gradually shifting, potentially paving the way for broader adoption of nuclear technologies as part of a balanced energy portfolio.
Moreover, the environmental implications of adopting SMRs are significant. Unlike fossil fuel plants, SMRs produce minimal greenhouse gas emissions.
