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.

The radionuclides in the gaseous effluent, in the water coolant from the research reactor, and in the surroundings were detected with gamma-ray spectrometry with and without using the Compton suppression technique, depending on the activity levels detected. All gamma-ray spectra were taken at various reactor power levels to investigate the relationship between the gamma-ray activities and the power levels. The linear proportionality between the activities and the power levels is valid to a certain extent. Activity in the water coolant was quite high, so in situ measurement was replaced by the sampling technique. The radionuclide 24Na in the coolant was specifically determined as a function of reactor operating time, and it tended to saturate over time. No manmade radionuclides were present in the surroundings except for 137Cs as fallout.
