The Senate Environment and Public Works Committee will hold a nomination hearing Wednesday for Ho Nieh, President Donald Trump’s nominee to serve as commission at the Nuclear Regulatory Commission.
Trump nominated Nieh on July 30 to serve as NRC commissioner the remainder of a term that will expire June 30, 2029, as Nuclear NewsWire previously reported.
Nieh has been vice president of regulatory affairs at Southern Nuclear since 2021, though since June 2024 he has been at the Institute of Nuclear Power Operations as a loaned executive.
A return to the NRC: If confirmed by the Senate, Nieh would be returning to the NRC after three previous stints totaling nearly 20 years.
2022 International High-Level Radioactive Waste Management Conference Speaker
Dr. Robert Ledoux currently serves as a Program Director at the Advanced Research Projects Agency—Energy. His areas of interest include the intersection of nuclear physics and non-proliferation, energy production, and transportation. He is the program director of the ARPA-E ONWARDS program, which aims to reduce the disposal impact of advanced reactor waste.
Prior to joining ARPA-E, Dr. Ledoux served as the Founder, President, and CEO of Passport Systems, a technology company in non-intrusive cargo inspection. At Passport Systems Dr. Ledoux co-invented powerful new technologies with the US Department of Homeland Security Domestic Nuclear Detection Office to aid in the non-intrusive inspection of cargo and co-authored over 20 US and international patents. Prior to founding Passport Systems, he served as Vice President of Pyramid Technical Consultants, developing hardware and software for the control of magnetic scanning systems and accelerator control used in semiconductor manufacturing equipment. Previously as an Associate Professor of Physics at the Massachusetts Institute of Technology, he studied high-energy nuclear interactions in search of new phases of hadronic matter.
