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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Nuclear materials testing project brings U.S. and U.K. expertise together
As nations look to nuclear energy as a source of reliable electricity and heat, researchers and industry are developing a new generation of nuclear reactors to fill the need. These advanced nuclear reactors will provide safe, efficient, and economical power that go beyond what the current large light water reactors can do.
But before large-scale deployment of advanced reactors, researchers need to understand and test the safety and performance of the technologies—especially the coolants and materials—that make them possible.
Now, the United States and the United Kingdom have teamed up to test hundreds of advanced nuclear materials.

Join us for a special members-only conversation on the Netflix series, "Meltdown: Three Mile Island." ANS Executive Director / CEO Craig Piercy will talk to Lake Barrett to hear his perspective on the series and will discuss what really happened at Three Mile Island.
About Lake Barrett
Lake is an independent consultant in the energy field serving in both government and commercial capacities in the nuclear energy and nuclear materials management areas for over 5 decades. He currently actively supports the recovery of the Fukushima nuclear reactor accident serving as a senior advisor to the Japanese Government’s International Research Institute for Nuclear Decommissioning and the Tokyo Electric Power Company. In these areas he has testified before the US Congress and has provided extensive public media explanations.
At the Department of Energy, he served as the Principal Deputy (10 years) and Acting Director (5 years) of the Office of Civilian Nuclear Waste Management reporting directly to five different Secretaries implementing the Nuclear Waste Policy Act of 1982, which involved complex scientific repository site evaluations and statutory processes, utility contract management and litigation, the integration of spent fuel storage and transportation considerations for existing reactor sites and for separate central storage facilities, and international and regulatory programs. Also, he served in Defense Programs (currently NNSA) as a director to change and improve national security, safety, and environmental protection cultures and operations at the Rocky Flats nuclear weapons plant leading to the successful restoration of plutonium operations and safe decommissioning.
At the Nuclear Regulatory Commission, he served at multiple senior technical and executive positions including being the onsite Director and senior federal official for the clean-up of the Three Mile Island reactor accident in the early 1980s.
Lake also served in multiple reactor design, construction, operation, and decommissioning positions for both submarine and commercial power reactors at Bechtel Power and Electric Boat Division of General Dynamics, including the last nuclear refueling of the SSN Nautilus.
He has BS and MS engineering degrees from the University of Connecticut, a registered professional engineer, Fellow of the American Nuclear Society, served on many national and international committees, and has received various honors such as the President’s Meritorious Excellence Award, Secretary of Energy’s Gold Award, DOE and NRC Meritorious Service Awards, and the Congressional Award for Exemplary Service Finalist. He is currently active in his Christ Venice Church as a Trustee/Leader, including serving on various international humanitarian missions.
