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.
Norman Hilberry was the 11th president of the American Nuclear Society and a charter member of the Society. He was also the first recipient of the Arthur Holly Compton Award in Education in 1967.
Norman Hilberry was born on March 11, 1899. He began his career as an Assistant in Physics at the University of Chicago in 1922, after getting his bachelor’s degree. In 1925, he moved to New York University, where he was first an Instructor in Physics at Washington Square College and then moved on to the College of Arts and Sciences.
In 1942, he joined the Manhattan Project, and a year later, became Assistant Director.
Following the war, in 1946, he moved to Argonne National Laboratory, starting as Assistant Director, and then moving on to Deputy Director. Between 1955 and 1956, he also served as the Director for Argonne’s International School for Nuclear Science and Engineering. From 1957 to 1961, he served as Director, and in 1961, became a Senior Scientist.
In 1964, he left Argonne to become a Professor of Nuclear Engineering at the University of Arizona, serving in that position until 1985, when he became Professor Emeritus until his death a year later.
During his career, he also held a number of directorships and advisory committee positions, including: Member, Board of Directors, Atomic Industry Forum (1961-1968); Member, Advisory Committee on U.S. Policy Toward the International Atomic Energy Agency, U.S. Department of State (1962); Member, Advisory Committee, U.S. Office of Emergency Preparedness, National Academy of Sciences (1968-1973); Member, Arizona Atomic Energy Commission (1969-1980); and Consultant, Subcommittee on the Public Understanding of Science, National Science Foundation (1977-1981).
He held a bachelor’s degree from Oberlin College (1921) and a PhD in physics from the University of Chicago (1941).
Norman Hilberry passed away on March 28, 1986.
