Ho Nieh nominated to the NRC
Nieh
President Trump recently nominated Ho Nieh for the role of commissioner in the Nuclear Regulatory Commission through the remainder of a term that will expire June 30, 2029.
Nieh has been the vice president of regulatory affairs at Southern Nuclear since 2021, though he is currently working as a loaned executive at the Institute of Nuclear Power Operations, where he has been for more than a year.
Nieh’s experience: Nieh started his career at the Knolls Atomic Power Laboratory, where he worked primarily as a nuclear plant engineer and contributed as a civilian instructor in the U.S. Navy’s Nuclear Power Program.
From there, he joined the NRC in 1997 as a project engineer. In more than 19 years of service at the organization, he served in a variety of key leadership roles, including division director of Reactor Projects, division director of Inspection and Regional Support, and director of the Office of Nuclear Reactor Regulation.

An improved digital computer model DYNAM/US has been developed for predicting thermally induced instability in a once-through boiling flow with superheat. The present model includes newly developed dynamic schemes to calculate subcooled boiling, transition boiling, bulk boiling, as well as superheat. Numerical results revealed that this digital model compared well with existing experimental data and was able to predict lower natural frequencies as well as the system frequency response at higher frequencies.
