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.

While nuclear security and nonproliferation efforts have been important to the stability and the peaceful use of nuclear energy around the world, the 2022 Russian invasion of Ukraine may be an inflection point in these efforts. From the occupation and ongoing operating conditions at the Zaporizhzhia Nuclear Power Plant to recent comments by several world leaders regarding the acquisition nuclear weapons, the existing nuclear security and nonproliferation order appears to be at a crossroad. Join our panelists for a discussion on the current state of nuclear security and nonproliferation and where they could go in the future!
