Division Spotlight
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

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 serving the people of the Tennessee Valley to make life better.
Before coming to TVA, Lyash served since 2015 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 procurement and power trading operations.
Lyash joined Progress Energy in 1993. Before leading the Energy Supply division at Progress, he served 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 also held a wide range of management and executive roles in Progress Energy’s nuclear program, including operations manager, engineering manager, plant manager, and director of site operations.
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.
Lyash earned a bachelor’s degree in mechanical engineering from Drexel University, and was honored with the Drexel University Distinguished Alumnus Award in 2009. He has held a senior reactor operator license from the Nuclear Regulatory Commission, and is a graduate of the U.S. Office of Personnel Management Executive Training Program and the Duke Fuqua School of Business Advanced Management Program.
Lyash is an avid golfer and fly fisher. He and his wife, Tracy, enjoy cooking, skiing, reading and charitable work – and spending time with their two married children and nine grandchildren. The Lyashes live in Knoxville, Tennessee.
