Senate EPW Committee to hold Nieh nomination hearing
Nieh
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.

Session Chair:

Alternate Chair:
John Mattingly (NCSU)
Session Organizer:
Panelists from industry and government will discuss the integration of safeguards and security into advanced reactor designs. Many emergent advanced reactor designs plan to use high-assay low-enriched uranium (HALEU) fuel, which is enriched to greater than 10% but less than 20% in uranium-235. In assessments of proliferation risk, the use of HALEU fuel should be considered in conjunction with other important reactor performance metrics, including higher power density, greater fuel utilization, longer refueling cycles, and higher fuel burnup, which may reduce overall proliferation risk. Panelists will discuss assessments of proliferation risk, measures planned to mitigate it in alternative advanced reactor designs, and by-design approaches to safeguards and security. They will also discuss the role of safeguards and security in enabling the US to maintain and expand its position in the global nuclear energy market and promote its own nonproliferation agenda.
