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 opening plenary will reflect on the profound and lasting impact of the landmark Reactor Safety Study (WASH-1400), published in 1975. Widely regarded as a foundational milestone in the development of probabilistic safety assessment (PSA), WASH-1400 transformed nuclear safety analysis and inspired generations of research and practice. The session is dedicated to the memory of two of its principal architects, Norman Rasmussen and Saul Levine, and will feature reflections and insights from former contributors to the study, as well as students, colleagues, and experts who have built upon its legacy. Through personal memories and technical perspectives, the session will honor the study’s enduring influence on the PSA discipline.
