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.

Kenneth Petersen is an executive consultant to the nuclear power industry, providing strategy, management, and technical consulting related to nuclear fuel and special nuclear material. Prior to his retirement in November 2021, Petersen was Exelon Generation Company’s (EGC’s) vice president for nuclear fuels. In this role, he provided governance and oversight for all aspects of the nuclear fuel cycle for Exelon’s fleet of 21 operational reactors and three retired reactors. He led Exelon’s fuel purchasing, nuclear core design and related safety analyses, and spent fuel management.
Petersen has nearly three decades of experience purchasing nuclear fuel, and during his 12 years as ECG’s vice president for nuclear fuels, he oversaw the company’s $1 billion annual budget for nuclear fuel procurement and managed a nuclear fuel contract portfolio valued at over $5 billion. His fuel supply responsibilities included the development of risk management metrics and strategic decisions related to fuel, inventory levels, and pricing mechanisms. In addition, he developed nuclear core design and safety analysis skills. He played a key role in the technical aspects of utilizing fuel in the reactors and was a major industry advocate for accident tolerant fuel designs, including coated fuel rods, high burnup, and high enrichment.
Petersen’s long history with spent fuel and special nuclear material includes his involvement with executing the U.S. Department of Energy’s (DOE’s) Standard Contract and, subsequently, EGC’s litigation and eventual settlement with the DOE. He also had governance and oversight over the installation of EGC-constructed independent spent fuel storage facilities. Petersen earned his bachelor’s and master’s degrees in nuclear engineering from the University of Wisconsin and began his career Commonwealth Edison upon graduation in 1988.
