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
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

Jeff Lyash is president and chief executive officer of the Tennessee Valley Authority. Appointed by the Board of Directors in February 2019, Lyash leads the nation’s largest public utility in its mission of service to the people of the Tennessee Valley region.
He is also chairman of the Nuclear Energy Institute executive committee, providing oversight to NEI on policy affairs on behalf of the U.S. nuclear industry.
Lyash is as comfortable talking with a crew in a plant as he is in the boardroom. His exceptional people skills and technical experience make him one of the top leaders in the energy industry.
Before taking the helm at TVA, Lyash served as president and CEO of Ontario Power Generation Inc., one of the largest electric generating companies in Canada with a diverse fleet of nuclear, hydroelectric, gas, biomass, and renewable generating stations.
Lyash was formerly the president of CB&I Power, where he was responsible for a full range of engineering, procurement, and construction of multi-billion-dollar electric generation projects in both domestic and international markets. He also provided operating plant services for nuclear, coal, gas, oil, and renewable generation.
Prior to joining CB&I, Lyash served as executive vice president of Energy Supply for Duke Energy, where he led engineering, maintenance, and operations of the company's 42,000-megawatt generation fleet, fuel procurement, power trading, major projects and construction, environmental programs, and health and safety programs.
Before the merger of Progress Energy and Duke Energy, Lyash was executive vice president of Energy Supply for Progress Energy. In this role, he oversaw Progress Energy's diverse 22,000-megawatt fleet of generating resources, including nuclear, coal, oil, natural
gas, and hydroelectric stations. In addition, Lyash was responsible for generating fleet fuel
Lyash joined Progress Energy in 1993, serving as executive vice president of corporate development, president and chief executive officer of Progress Energy Florida, senior vice president of Energy Delivery Florida, and vice president of Transmission.
Lyash began his career in the utility industry in 1981 and worked for the U.S. Nuclear Regulatory Commission in senior technical and management positions throughout the Northeast and in Washington, D.C. He received the NRC Meritorious Service Award in 1987.
