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.

ANS Chicago-Great Lakes Local Section Event
December 5, 2024|7:00–8:00PM (8:00–9:00PM EST)
Available to All Users
On September 20, 2019, the Three Mile Island Unit 1 generating station shutdown for economic reasons, despite being one of the best performing plants on the grid. Exactly five years later, Constellation Energy Generation (CEG) announced the unit would re-start as the Crane Clean Energy Center (CCEC), including a 20-year power purchase agreement with Microsoft to power Microsoft’s growing artificial intelligence (AI) and data center portfolio.
During an ANS Chicago-Great Lakes Local Section hybrid event, Trevor Orth, Plant Manager of Crane Clean Energy Center, and Darani Reddick, Director, Nuclear Regulatory Strategy & Policy, Constellation Energy Generation, LLC, discussed the technical aspects of the restart including the material condition and improvements, and touch on the still-evolving relicensing and regulatory environment.
