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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.
Workshop
Thursday, April 4, 2024|3:00–4:30PM EDT|Thomas Building Room 104
Session Organizers:
Zach Van Horn (Penn State University - Radiation Science & Engineering Center)
Jessi Altiero (Penn State University)
Join Hannah Wiseman (Penn State University), Khalil Ryan (Good Energy Collective), Emma Houston (University of Tennessee - Knoxville), and Natalie Houghtalen (ClearPath) in a discussion on how nuclear engineering and nuclear technology tie into the world of policy. Attendees will hear about how nuclear energy fits into general clean energy policy, such as the Bipartisan Infrastructure Law, the Inflation Reduction Act, current DoE programs like the Civil Nuclear Credit Program, current bills making their way through Congress, and future policy decisions. Attendees should leave the workshop with a more thorough understanding of why the clean energy policy includes nuclear energy and why nuclear energy benefits from the clean energy policy. Attendees should have a basic understanding of past, current, and future acts/bills and a basic understanding of clean energy engineering.
Speakers
Khalil Ryan
Mr. Khalil Ryan is a recent graduate of the University of Massachusetts Amherst. Born and raised in Boston, he majored in Political Science following a burgeoning interest in politics after the 2016 presidential election. Before his time in university, he spent a semester studying abroad in the Bahamas, focusing on marine life research and environmental conservation. He is passionate about foreign policy and environmental protection. Khalil serves as a policy analyst at Good Energy Collective, focusing on a project concerning nuclear diplomacy to aid in the gradual decarbonization of global energy sources. Khalil’s main area of work is introducing civil nuclear energy to nations seeking to move away from the traditional carbon-based energy infrastructure through partnerships with the United States civil nuclear export regime. Besides his main focus of work, Khalil is also working on several short papers concerning the global fuel supply chain and the current leading global nuclear export regimes.
Emma Houston
Ms. Emma Houston is a graduate student at the University of Tennessee pursuing a Ph.D. in Nuclear Engineering. She is a Nuclear Nonproliferation and International Safeguards fellow where she studies international safeguards for advanced reactors. She received her bachelor's from the University of Tennessee’s Nuclear Engineering Department in 2022. Emma is passionate about nuclear nonproliferation, international safeguards, and the technical and policy challenges associated with both. She served as the 2023 ANS Student Conference co-chair and currently serves as the 2024 Nuclear Engineering Student Delegation (NESD) chair.
Natalie Houghtalen
Ms. Natalie Houghtalen is a Policy Advisor at ClearPath. As part of ClearPath’s focus on clean energy and industrial technologies, Natalie leads the development of policies to advance advanced nuclear and hydrogen technologies as well as clean industrial heat, integrated energy systems, and spent fuel management. Natalie serves as a member of multiple industry trade associations, including the Clean Hydrogen Future Coalition, Nuclear Energy Institute, and the US Nuclear Industry Council. She first joined ClearPath in 2019 with a background in nuclear engineering.
Hannah Wiseman
Prof. Hannah Wiseman is a Professor of Law, and Wilson Faculty Fellow in the College of Earth and Mineral Sciences, and Institutes of Energy and the Environment co-funded Faculty Member. Professor Wiseman teaches and writes in the areas of Energy Law, Oil & Gas Law, Land Use Regulation, Environmental Law, and Administrative Law. Her work focuses on the mechanics and design of regulation and governance in these areas including the challenges of determining appropriate governance levels, fostering effective experimentation, and addressing expansions in the scale of regulated activities.
