The transformation of the NRC: 50 years of commissioners
The dust is beginning to settle following the whirlwind of changes at the Nuclear Regulatory Commission over the past year, and 2025 ultimately may be viewed as a transformative year, as well as the year the NRC celebrated its golden anniversary. The 12 months of that milestone year brought more change to the agency in its composition, its mandate, and its relationship to the executive branch than any comparable period in the preceding four decades.
Now at 51 years and counting, the NRC is working with a full commission and issuing new rulemakings to both regulate and support the next round of nuclear deployments. With the turbulence of 2025 still fresh in our minds, Nuclear News decided it was a good time to revisit the professional backgrounds of all 42 NRC commissioners who have served over the agency’s 50-year history to see how the composition of the commission has evolved over time.
Dr. Thomas L. Sanders joined the American Nuclear Society (ANS) in 1987, joining the Fuel Cycle and Waste Management, Nuclear Criticality and Nuclear Nonproliferation Divisions. Since the start of his membership at ANS, he has served as Vice President, President, and Board Executive.
Currently, he is the Associate Laboratory Director for Clean Energy Initiatives at the U.S. Department of Energy’s (DOE) Savannah River National Laboratory (SRNL), operated by Savannah River Nuclear Solutions (SRNS), LLC, where he is responsible for developing new opportunities in energy technology development.
Dr. Sanders is a recognized expert on international relations and has been working on rebuilding the U.S. nuclear export industry through the development of small modular. Prior to working at SRNL, he spent 27 years at Sandia National Laboratory (SNL).
He was appointed to a second term on the Civil Nuclear Trade Advisory Committee (CINTAC), which serves the Secretary of Commerce on trade issues facing the U.S. civil nuclear industry. Additionally, Dr. Sanders was selected as a U.S. member of Russian President Medvedev’s Global Energy Prize Committee and was the cofounder and former Vice President of the American Council on Global Nuclear Competitiveness (ACGNC).
His many accomplishments include testifying to Congress, the Blue Ribbon Commission, and Secretarial Officers from DOE, the Departments of State and Defense, the Nuclear Regulatory Commission (NRC), and other agencies. He also developed a complementary partnership initiative between seven U.S. and nine Russian Lab Directors.
Dr. Sanders earned a BS, MS and PhD from the University of Texas – Austin in Nuclear Engineering. He has authored more than 100 journal articles and papers on subjects from fusion and fast fission breeder reactor systems, to criticality safety of spent fuel transport, storage, and disposal systems. He is a member of ACGNC, American Society of Mechanical Engineers and the Institute of Nuclear Materials Management.
He also served as a nuclear operator and supervisor on U.S. Navy nuclear submarines.
