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.
Meeting Spotlight

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.
