ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

High-temperature plumbing and advanced reactors
The use of nuclear fission power and its role in impacting climate change is hotly debated. Fission advocates argue that short-term solutions would involve the rapid deployment of Gen III+ nuclear reactors, like Vogtle-3 and -4, while long-term climate change impact would rely on the creation and implementation of Gen IV reactors, “inherently safe” reactors that use passive laws of physics and chemistry rather than active controls such as valves and pumps to operate safely. While Gen IV reactors vary in many ways, one thing unites nearly all of them: the use of exotic, high-temperature coolants. These fluids, like molten salts and liquid metals, can enable reactor engineers to design much safer nuclear reactors—ultimately because the boiling point of each fluid is extremely high. Fluids that remain liquid over large temperature ranges can provide good heat transfer through many demanding conditions, all with minimal pressurization. Although the most apparent use for these fluids is advanced fission power, they have the potential to be applied to other power generation sources such as fusion, thermal storage, solar, or high-temperature process heat.1–3
Advanced Reactor Safety (ARS) SPeaker
Dr Han-Gon KIM is the President of Innovative SMR Development Agency.
The agency is a foundation established by Korean Government to develop i-SMR.
Dr Kim graduated from nuclear engineering department of Seoul National University in 1988 and completed his master and Ph.D. degrees in nuclear engineering at KAIST in 1990 and 1993, respectively. Dr Kim worked to develop APR1400 in Korea Hydro and Nuclear Power Co, (KHNP) since 1997. And he had major role to get the standard design approval of APR1400 at 2002. In 2006, he led the national project to develop GEN III+ PWR, APR+.
From 2015, he was the project manager for APR1400 USNRC design certification and EUR certification. From 2020, he was the president of Central Research Institute (CRI) of KHNP and he planned the innovative SMR development with the Korean government.
