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.
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.

Metz on Harold Denton: Memories of a life in nuclear safety
A number of years ago, historian and writer Chuck Metz Jr. was at the Bush’s Visitor Center in Tennessee’s Great Smoky Mountains when he ran into former Nuclear Regulatory Commission official Harold Denton and his wife. Metz was at the visitor center, which opened in 2010 and is now a tourist hotspot, because, as he explained to the Dentons at the time, he had overseen the development of its on-site museum and had written a companion coffee-table history book.
The chance meeting turned into a friendship and a fruitful collaboration. Denton, who in 1979 was the public spokesperson for the NRC as the Three Mile Island-2 accident unfolded, had been working on his memoir, but he was stuck. He asked Metz for help with the organization and compilation of his notes. “I was about to retire,” Metz said, “but I thought that exploring the nuclear world might be an interesting change of pace.”
Denton passed away in 2017, but by then Metz had spent many hours with his fast friend and was able to complete the memoir, Three Mile Island and Beyond: Memories of a Life in Nuclear Safety, which was published recently by ANS. Metz shared some of his thoughts about Denton and the book with Nuclear News. The interview was conducted by NN’s David Strutz.
As vice president of nuclear strategy & development for Exelon, Marilyn Kray leads major initiatives on current and advanced reactor designs to create growth opportunities that leverage Exelon’s nuclear operations competency. These initiatives include pursuing operational service agreements, both domestically and internationally, as well as engaging with advanced reactor developers in order to evaluate potential business opportunities and future technology deployment.
She served as president of NuStart Energy Development LLC, an industry consortium formed to develop the process for preparing the combined construction and operating license applications for the first new nuclear plant construction in the United States in over 30 years.
Her in-depth knowledge of the global nuclear industry comes from years of experience including as vice president of Exelon Nuclear Partners. In this role, she led international business development. Prior to this, she served as Exelon’s vice president of nuclear acquisition support, where she pioneered internal processes for due diligence and plant transitions. The result was the successful purchases of the Three Mile Island, Clinton, and Oyster Creek generating stations. More recently, she led the acquisition of the FitzPatrick nuclear power plant.
Marilyn began her career with Exelon in the licensing organization for the Peach Bottom Atomic Power Station. Prior to joining Exelon, she was a reactor engineer and project manager for the U.S. Nuclear Regulatory Commission. She has testified in front of Congress on multiple occasions regarding nuclear development in the United States. Throughout her career Marilyn has served in leadership roles as Exelon’s representative to the Nuclear Energy Institute and the Electric Power Research Institute.
Marilyn has been a member of ANS since 2007 and serves in the Education, Training, and Workforce Development Division as well as the Operations and Power Division. In 2007, she received the American Nuclear Society’s Utility Leadership Award. Other recognitions Marilyn has received include the World Nuclear Association award for Distinguished Contribution to the Peaceful Use of Nuclear Technology, and under her leadership the NuStart organization was one of four finalists for the 2012 Edison Award.
Marilyn is a graduate of Carnegie-Mellon University, with a Bachelor of Science degree in Chemical Engineering.
