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.

The U.S. nuclear industry is currently in the middle of a historic shift towards the utilization of risk-informed performance-based (RIPB) design and licensing approaches. Moving from a supporting role, RIPB methods are now leading key reactor decision-making. Such methods permit flexibility and encourage consistency between the plant’s risk profile and appropriate design and licensing actions. However, RIPB approaches are not without their difficulties, including the need for detailed probabilistic assessments and addressing a lack of historic precedent in many areas. This panel explores the current transition to RIPB approaches, including efforts that are currently underway, plans for the future, and hurdles to overcome.
