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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

Resurrecting Three Mile Island
When Exelon Generation shut down Three Mile Island Unit 1 in September 2019, managers were so certain that the reactor would never run again that as soon as they could, they had workers drain the oil out of both the main transformer and a spare to eliminate the chance of leaks. The company was unable to find a buyer because of the transformers’ unusual design. “We couldn’t give them away,” said Trevor Orth, the plant manager. So they scrapped them.
Now they will pay $100 million for a replacement.
The turnaround at the reactor—now called the Crane Clean Energy Center—highlights two points: how smart Congress was to step in with help to prevent premature closures with the zero-emission nuclear power production credit of 0.3 cents per kilowatt-hour (only two years too late), and how expensive it is turning out to be to change course.
Utility Working Conference and Vendor Technology Expo (UWC 2023)
The Honorable Annie Caputo was sworn in as a Commissioner of the U.S. Nuclear Regulatory Commission on Aug. 9, 2022, and is serving the remainder of a five-year term ending June 30, 2026. Commissioner Caputo previously served on the NRC Commission from 2018 to 2021.
Commissioner Caputo has over two decades of government and private-sector experience in nuclear energy and security policy. Caputo has a distinguished career as a nuclear engineer and, policy advisor, and has made significant contributions related to federal nuclear energy policy.
Prior to her most recent appointment as an NRC Commissioner, she consulted for the Department of Energy Idaho National Laboratory promoting international collaboration on advanced nuclear reactors. Prior to her work at INL, she served a short-term assignment with the United States Senate Armed Services Committee, where she assisted with the National Nuclear Security Administration’s portfolio.
Prior to joining the NRC, she spent over 13 years as a staff member in the United States Congress advancing key policies and initiatives related to national security, science and technology, energy, and the environment. She served as senior policy advisor for Chairman John Barrasso and then-Chairman James Inhofe on the Senate Environment and Public Works Committee. Notably, she supported the Senators’ work on nuclear energy policy and NRC oversight.
From 2005-2006 and 2012-2015, she worked for the House Committee on Energy & Commerce, overseeing a variety of nuclear energy issues. She supported then-Chairman Joe Barton and Fred Upton with oversight of DOE and NRC.
Prior to her positions on Capitol Hill, she worked for Exelon Corporation in a variety of positions of increasing responsibility in both nuclear generation and governmental affairs., notably serving as the Executive Assistant to the Senior Vice President of Fuel Procurement.
She earned a bachelor’s degree in Nuclear Engineering from the University of Wisconsin-Madison, with an emphasis in communications.
In addition to her many accomplishments, she brings ingenuity to her hobbies as an avid quilter and crafter. She enjoys sharing her talents and creating one-of-a-kind pieces for others.
