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.

Validation of thermal-hydraulic codes for system design and safety analysis is dependent on applicable and appropriately scaled experimental data. There are several scaling methodologies for justifying the use of data from small-scale facilities for simulation of large-scale reactor systems. These methods continue to be improved and extended to new situations. This panel will discuss the "art of scaling" and progress in development of scaling methods.
